A desktop HTTP and HTTPS proxy for macOS, Windows, and Ubuntu. It lets developers, QA engineers, and testing specialists inspect and modify network traffic from their own browsers, mobile apps, and devices.

The Base tier is free with no time limit, but limited in functionality. You can start using it right away, no account needed. The Pro subscription lifts all limits; it needs an account.

Does it work with HTTPS?

Yes, by installing a local root certificate for decryption. Fully optional — you choose what to decrypt, and can remove the certificate any time.

The proxy runs locally on your machine: captured data stays on your device and nothing is sent to external servers. HTTPS is decrypted only after you install a local certificate yourself. You remain responsible for whose traffic you debug.

What must Solpuga not be used for?

It is a tool for debugging your own systems. It must not be used to intercept the traffic of third parties without their consent, to bypass protection on services that are not yours, to covertly monitor other people’s devices, or to reach resources restricted by the law of the Russian Federation.

Anyone with lawful access to the system whose traffic they're debugging: a regular user on their own machine, an employee within company policy, or a contractor under agreement.

Can I use it with iOS / Android devices?

Yes. Point the device's Wi-Fi proxy setting to the proxy address, then install and trust the Solpuga certificate. Android also supports proxying over USB.

What protocols does it support?

HTTP/1.1, HTTPS, Server-Sent Events (SSE), and WebSocket — plaintext or encrypted, with full visibility into headers, bodies, and timing. Streaming responses show event by event as they arrive, without waiting for the connection to close.

Public Offer for the Grant of the Right to Use the "Solpuga" Computer Program

Revision: 1.0
Date of publication on the Site: 23.09.2026

Convenience translation. This document is an English translation of the Russian-language Public Offer published at https://solpuga.pro/ru/oferta, provided for information purposes only. In the event of any discrepancy between the English and Russian versions, the Russian version prevails.

This document constitutes an official proposal (public offer) to enter into a license agreement on the terms of a simple (non-exclusive) license with any natural person having full legal capacity, as well as with any legal entity or individual entrepreneur acting through an authorized representative (the "Licensee"), in accordance with Clause 2 of Article 437 of the Civil Code of the Russian Federation.

Acceptance of this Offer is equivalent to concluding an agreement on the terms set out below and means full and unconditional acceptance of all of its terms without any exceptions or reservations. The agreement is deemed concluded under the simplified procedure provided for computer programs by Clause 5 of Article 1286 of the Civil Code.

If the Licensee is a Consumer, the terms of the Offer apply to the extent they do not conflict with the mandatory provisions of Law of the Russian Federation No. 2300-1 of 07.02.1992 "On Protection of Consumer Rights" and Chapter IV of the Uniform Rules. Terms that infringe Consumer rights are void (Article 16 of the Law on Protection of Consumer Rights) and do not apply.

1. The Licensor

1.1. Licensor: Novikova Daria Sergeevna — a natural person, a citizen of the Russian Federation, applying the special "Professional Income Tax" regime (Federal Law No. 422-FZ of 27.11.2018).

1.2. Taxpayer identification number (INN): 637211237896. VAT is not applicable.

1.3. Contact email: support@solpuga.pro.

1.4. Site: https://solpuga.pro, including subdomains and language versions (the "Site"). The current revision of the Offer is available at https://solpuga.pro/en/oferta. Previously effective revisions are available at addresses of the form https://solpuga.pro/en/oferta/1.0, where the last element of the address is the revision number

1.5. The Licensor is the author and holder of the exclusive right to the Program and is entitled to grant licenses.

2. Definitions

2.1. Program — the "Solpuga" computer program: a cross-platform desktop HTTP/HTTPS proxy for debugging network traffic. In Russian-language materials on the Site the Program may be referred to as "Сольпуга"; both spellings denote the same Program.

2.2. License — a simple (non-exclusive) license to use the Program within the limits established by the Agreement.

2.3. Tariff — the terms on which the License is granted, as published on the Site at the moment of Acceptance: term, number of devices, set of features, price.

2.4. Subscription — a Tariff with automatic renewal (clauses 5.6–5.9).

2.5. Account — the Licensee's account, identified by the Licensee's email address. The Account provides access to the License in the Program and in the personal cabinet on the Site, and allows the Subscription to be managed.

2.6. Remuneration — the license remuneration, equal to the price of the selected Tariff.

2.7. Payer — the person paying the Remuneration: the Licensee or another person acting in the Licensee's interests.

2.8. Payment Aggregator — the legal entity that accepts payments in the Licensor's favor under a contract with the Licensor. Details of the Payment Aggregator handling a particular payment are shown to the Payer on the payment page.

2.9. Consumer — a Licensee who is a natural person acquiring the License solely for personal, family, household or other needs unrelated to business activity.

2.10. Uniform Rules — the Uniform Rules in the Field of Consumer Protection approved by Decree of the Supreme State Council of the Union State No. 6 of 06.12.2024. They treat the Program and the License as a digital product.

3. Subject Matter of the Agreement

3.1. The Licensor grants the Licensee, for Remuneration, the right to use the Program under a simple (non-exclusive) license, and the Licensee undertakes to pay the Remuneration and to observe the limits of use.

3.2. The Program is intended for the interception, inspection, filtering, modification and debugging of HTTP and HTTPS traffic of applications, browsers and mobile devices. It is installed and executed on the Licensee's device; intercepted traffic, sessions and rules are stored locally and are not transmitted to the Licensor. The Program is not a cloud service.

3.3. The list of features, the supported platforms and the system requirements are published on the Site and constitute information about the Program. The order and the confirmation sent to the Licensee record the Tariff chosen and the term of the License; the number of devices included in the Tariff is stated when the order is placed and is available in the personal cabinet. The system requirements and the documentation are available on the Site at permanent addresses.

3.4. Permitted means of use: reproduction by installing and recording the Program in computer memory; launching and using it for its functional purpose; making a backup copy to replace a lawfully acquired copy — within the number of devices provided for by the paid Tariff.

3.5. Territory — worldwide, unless the Tariff provides otherwise. The term of the License is stated in the Tariff; for a Subscription the License is renewed for each subsequent paid period.

3.6. The right to sublicense is not granted unless expressly agreed in writing. The exclusive right, the source code, trademarks, domain name, design and documentation of the Program are neither assigned nor granted to the Licensee.

3.7. If the Tariff includes updates, the Licensor provides access to them for the paid period of the License on an "as is" basis, without any obligation to release particular features by a particular date. After that period the previously installed version remains with the Licensee and may be used on the free tier (clause 11.6).

4. Conclusion of the Agreement (Acceptance)

4.1. The Offer takes effect upon publication on the Site and remains in force until withdrawn by the Licensor. Withdrawal does not affect agreements already concluded.

4.2. Acceptance consists of the Licensee performing all of the following: selecting a Tariff; signing in to an Account or creating one; ticking the box "I accept the terms of the public offer" or taking another unambiguous action on the Site; and paying the Remuneration in full.

4.3. The Agreement is deemed concluded at the moment the Payment Aggregator confirms successful payment.

4.4. By accepting, the Licensee confirms that it has the requisite legal capacity (and, where acting on behalf of a legal entity or individual entrepreneur, the requisite authority), has provided accurate data, has reviewed the description of the Program, the Tariff, the procedure for granting the License and the refund terms — and, where a Subscription is selected, the amount and frequency of subsequent charges and how to cancel them — and understands that it is acquiring the right to use a computer program rather than a tangible good.

4.5. Where the Payer and the Licensee are different persons, the Payer warrants that it is authorized to pay in the Licensee's interests. The License is bound to the Account in which the order was placed.

5. Remuneration and Payment

5.1. The Remuneration equals the price of the selected Tariff as stated in the order at the moment of payment. The price is stated in Russian rubles and includes all mandatory payments of the Licensor connected with performance of the Agreement.

5.2. The Licensor may change Tariff prices. A new price applies only to orders paid after the change is published; Remuneration already paid is not subject to recalculation. The price on renewal of a Subscription is determined by clause 5.6.

5.3. Payment is made by cashless means through the Payment Aggregator using the methods available on the payment page. For a Subscription only those payment methods that allow subsequent automatic charging are available. The payment obligation is deemed performed at the moment successful payment is confirmed.

5.4. The Licensor does not receive or store the Payer's bank card details: they are processed by the Payment Aggregator and by credit institutions.

5.5. After payment, a receipt generated in accordance with Federal Law No. 422-FZ is sent to the Payer at the email address given at payment.

5.6. Subscription. By selecting a Tariff with a Subscription, the Licensee instructs that the Remuneration for each subsequent License period be charged to the payment instrument used for the first payment, without further instruction. Each charge equals the Tariff price agreed when the Subscription was taken out and does not change when prices on the Site change. The charging frequency equals the License term under the Tariff. No later than three days before each charge the Licensor notifies a Consumer Licensee of the upcoming charge and of how to cancel it.

5.7. Cancelling automatic renewal. The Licensee may cancel automatic renewal at any time and without giving reasons — in the personal cabinet or by writing to the address in clause 1.3. Cancellation stops subsequent charges and does not interrupt the period already paid for: the License remains in force until that period ends. Cancellation is not in itself a withdrawal from the Agreement and does not deprive the Licensee of the rights under Section 9.

5.8. Failed charge. If a charge fails, the Licensor may retry for 14 (fourteen) calendar days from the end of the paid period. The new paid period runs from the day the charge succeeds. If the Remuneration is not received within that period, the Subscription terminates and the Licensee is notified at the email address of the Account.

5.9. The Licensor declining to renew. The Licensor may stop accepting new Subscriptions and may decline to renew existing Subscriptions, having notified the Licensee at the email address of the Account no later than 30 (thirty) days before the end of the paid period. Declining to renew stops subsequent charges and does not interrupt the period already paid for: the License remains in force until that period ends.

6. Grant of the License

6.1. The License is granted by binding it to the Licensee's Account, after which it is available in the Program and in the personal cabinet on the Site upon signing in to the Account. No separate activation codes are used. The Program's distribution package is freely downloadable from the Site.

6.2. The moment of delivery of the License — and, for a Consumer, also the moment access to the digital product is provided — is the moment the License is bound to the Account and becomes available upon signing in. The Licensor notifies the Licensee of this at the email address of the Account; the moment of delivery does not depend on receipt of that notification.

6.3. Time for granting. Clause 1 of Article 43 of the Uniform Rules permits a procedure other than immediate provision where the contract provides for one. The Agreement establishes the following procedure: the License is granted automatically after payment is confirmed, and where automatic granting is temporarily impossible (technical failure, manual payment review, anti-fraud checks) — within no more than 5 (five) business days from confirmation of payment. Where the Licensor has notified the Licensee of the delay by email, that period is no more than 10 (ten) business days from confirmation of payment.

6.4. The Licensee downloads the distribution package, installs the Program, signs in to the Account within it, and ensures that its hardware and operating system meet the system requirements published on the Site. The License is effective on the devices on which the Account has been signed in to, within the number of devices provided for by the Tariff.

6.5. Access to the License is restored by restoring access to the Account or, where that is impossible, by writing to the address in clause 1.3 with confirmation that the Account belongs to the person making the request. Confirmation of payment alone does not give access to the Account: the Payer and the Licensee may be different persons (clause 2.7).

6.6. Number of devices. A slot within the number of devices provided for by the Tariff is freed by releasing the device in the Program or in the personal cabinet, or — where the Licensee cannot do so itself — on request to the address in clause 1.3. Reinstallation of the operating system and the replacement or loss of a device are not grounds for refusing to free a slot.

7. Limits of Use and Prohibitions

7.1. The Licensee may use the Program only by the means listed in clause 3.4 and only on the number of devices provided for by the Tariff.

7.2. The Licensee is prohibited from:

a) distributing, selling, renting out or transferring to third parties copies of the Program or access to the Account. Where the Licensee is a legal entity or an individual entrepreneur, the Program is used by its employees within the paid number of devices, and such use is not treated as a transfer to third parties;

b) providing the Program as a remote access service to unauthorized persons without the Licensor's separate written consent;

c) circumventing, disabling or forging licensing mechanisms, or using forged or generated licenses or other persons' Accounts;

d) decompiling, disassembling or otherwise attempting to obtain the source code of the Program, except as expressly permitted by Article 1280 of the Civil Code;

e) removing or altering copyright notices, the "Solpuga" name or information about the rightsholder;

f) using the Program for unlawful activity, including unauthorized access to the information systems of others, breach of the secrecy of communications, and distribution of malware.

7.3. The Licensee is solely responsible for the lawfulness of traffic interception within its own infrastructure, for the decision to install the local root certificate and to remove it after use, and for notifying the users of the devices it controls where such notification is required by law. This clause does not release the Licensor from liability for defects in the Program itself (section 8).

7.4. A breach of clause 7.2 is a material breach of the Agreement.

8. Quality of the Program. Defects

8.1. In relations with a Licensee who is not a Consumer, the Program is provided on an "as is" basis: the Licensor does not warrant that it will meet that Licensee's subjective expectations, operate without interruption on any hardware configuration, or achieve any commercial result.

8.2. The Licensor warrants that it is entitled to grant the License and that use of the Program within the limits of the License does not infringe any third-party exclusive rights known to the Licensor.

8.3. A defect means a failure of the Program to conform to the functional purpose declared on the Site as at the date of payment and/or to mandatory requirements, which prevents the Program from being used for its purpose on a supported platform where the system requirements are met. In relation to a Consumer, the notion of a defect of a digital product is determined by the Uniform Rules and the Law on Protection of Consumer Rights and cannot be narrowed by this Offer.

8.4. The following are not recognized as defects: the absence of a feature not declared in the description as at the date of payment; errors caused by the Licensee's actions, by malware or by modification of the Program; and the behavior of third-party applications and servers. Known compatibility limits — including those affecting particular VPNs, antivirus software and corporate proxies — are stated in the system requirements on the Site, against which conformity of the Program is assessed under clause 8.3.

8.5. On discovering a defect the Licensee sends an enquiry to the address in clause 1.3. The Licensor asks that, where possible, the enquiry describe the defect, the version of the Program, the platform and the steps to reproduce it: this speeds up consideration and is not a condition of accepting the enquiry.

8.6. A Consumer who discovers a defect that was not disclosed by the Licensor may assert the claims provided for by Article 44 of the Uniform Rules.

8.7. In relation to a Licensee who is not a Consumer, the Licensor may at its option: remedy the defect by an update, provide a workaround, reduce the Remuneration proportionately, or refund the Remuneration and terminate the License.

9. Withdrawal from the Agreement. Refunds

9.1. Until the License has been delivered (clause 6.2) the Licensee may withdraw from the Agreement and demand a full refund of the Remuneration paid.

9.2. A Consumer may withdraw from a License of proper quality, without giving reasons, and demand a full refund of the Remuneration within 7 (seven) days, not counting the day of payment (clause 4.3), in accordance with Article 48 of the Uniform Rules. After that period the Remuneration for a paid period that has begun is not refundable, except in the cases provided for by clauses 9.3 and 11.5, where the refund amount is determined by the applicable clause.

9.3. After delivery of the License, a refund beyond clause 9.2 is made where: the Program has a defect (clause 8.3); the License was not granted on time through the Licensor's fault; a refund is mandatory under other imperative provisions of law; or the Licensor decides to refund voluntarily.

9.4. A refund request is sent to the address in clause 1.3. The Licensor asks that it state the email address of the Account, the date and amount of payment and the payment identifier (if known): this speeds up consideration and is not a condition of accepting the request. No ground need be stated for a withdrawal under clause 9.2.

9.5. The refund is made by the same means as the payment, within the periods established by the Law on Protection of Consumer Rights and the Uniform Rules. No Payment Aggregator commission is withheld from a Consumer. Actual crediting to the Payer's account may take additional time at the issuing bank.

9.6. The License terminates and is revoked, and the Subscription terminates with no further charges, from the moment the Licensor sends notice that the request has been granted to the email address of the Account. The Program continues to work on the free tier (clause 11.6).

9.7. A Licensee who is not a Consumer does not have the right provided for by clause 9.2: for such a Licensee a refund is made on the grounds set out in clauses 9.1 and 9.3 or under a separate written agreement.

10. Personal Data

10.1. The Licensee's personal data are processed in order to conclude and perform the Agreement, grant the License and send the receipt, communicate about the order, comply with obligations under tax legislation, protect against fraudulent payments, and handle enquiries.

10.2. The categories of data processed, the legal grounds, retention periods, recipients, and the rights of data subjects together with the procedure for exercising them are determined by the Personal Data Processing Policy: https://solpuga.pro/en/privacy. Where this Section and the Policy differ, the Policy applies.

11. Term of the Agreement. Amendment and Termination

11.1. The Agreement takes effect upon Acceptance and remains in force for the term of the License.

11.2. The Licensor may amend the Offer unilaterally. A new revision takes effect upon publication on the Site unless it states a later date. It applies to agreements already concluded only to the extent that it does not worsen the Licensee's position in respect of the Tariff already paid for. In relation to a Consumer, unilateral amendment of the terms of a concluded agreement is permitted only in the cases and within the limits provided by law.

11.3. Use beyond the License. Use of the Program beyond the rights granted under the Agreement — including on more devices than the paid Tariff provides for, and with any circumvention, disabling or forgery of the licensing mechanisms (clause 7.2) — entails the liability provided for by clause 3 of Article 1237 of the Civil Code; termination of the Agreement is not required for this. The rights belonging to the Licensee by virtue of Article 1280 of the Civil Code (sub-clause d) of clause 7.2) are not affected by this clause, and use of the Program on the free tier (clause 11.6) is not use beyond the License. The Licensor may apply technical means that confine use of the Program to the limits of the paid Tariff; refusing use beyond the License is not a failure by the Licensor to perform its obligations and gives rise to no claims under sections 8 and 9.

11.4. Unilateral withdrawal by the Licensor. The Licensor may withdraw from the Agreement unilaterally and out of court only in the cases provided for by law, including where the Remuneration has not been paid and where a payment is declared invalid by the issuing bank or classified as fraudulent by the Payment Aggregator. The Agreement terminates upon the expiry of 30 (thirty) days from the day the Licensee receives the notice of withdrawal, if the Remuneration has not been received within that period (clause 4 of Article 1237 of the Civil Code).

11.5. Discontinuation of support. The Licensor may discontinue the release of updates and support for the Program, having notified the Licensee at the email address of the Account no later than 30 (thirty) days in advance. The paid period is not interrupted: until it ends the License continues to operate. Where that cannot be ensured, the Licensor refunds the part of the Remuneration proportionate to the unexpired paid period.

11.6. The free tier after the License ends. Expiry of the term of the License, cancellation of the Subscription, a refund of the Remuneration and termination of the Agreement on any other ground do not oblige the Licensee to delete the Program: only the features that the paid Tariff added to the free one become unavailable, and the Program itself continues to work on the free tier. Use of the Program on the free tier is not governed by this Agreement — it is governed by the User Agreement (https://solpuga.pro/en/terms), which also determines the composition of the free tier, including its amendment and discontinuation.

12. Liability

12.1. In relations with a Licensee who is not a Consumer, the Licensor is not liable for indirect damages, lost profit, loss of data on the Licensee's side, business downtime or third-party claims, nor for failures of communication networks, banks, the Payment Aggregator or operating systems; and the Licensor's aggregate liability for claims connected with a particular order is limited to the amount of Remuneration actually paid under that order. This does not apply in cases of the Licensor's intent or gross negligence, or where such a limitation is void by law.

12.2. Clause 12.1 does not apply to a Consumer.

12.3. The Licensee shall compensate the Licensor for losses caused by a breach of Section 7 and by unlawful use of the Program.

12.4. The Parties are released from liability for non-performance caused by force majeure, provided the other Party is notified within a reasonable time.

13. Dispute Resolution

13.1. Governing law — the law of the Russian Federation.

13.2. Disputes with a Consumer are considered under the rules of jurisdiction established by Article 17 of the Law of the Russian Federation "On Protection of Consumer Rights", at the Consumer's choice. Where no period for a reply is set by law, the Licensor answers within a reasonable time.

13.3. For a Licensee who is not a Consumer, the pre-action claim procedure is mandatory; disputes are considered by the competent court in accordance with the jurisdiction established by the procedural legislation of the Russian Federation.

14. Final Provisions

14.1. The invalidity of any single provision of the Offer does not entail the invalidity of the remaining provisions.

14.2. Correspondence at the email address of the Account and at the address in clause 1.3 is recognized as written form. Legally significant messages are deemed delivered from the moment they reach the relevant email address, including where the addressee has not read the message for reasons within the addressee's control (Article 165.1 of the Civil Code).

14.3. Terms of the Offer that allow more than one reading are interpreted in the Consumer's favor.

14.4. The Offer is addressed to persons located in the territory of the Russian Federation and the Republic of Belarus; settlements under the Agreement are made in roubles of the Russian Federation, and the Licensor does not direct its activities to the territory of any other state. A Licensee located outside the Russian Federation is solely responsible for ensuring that the acquisition and use of the Program comply with the law of the country of its location (stay), including rules on the import and use of cryptographic (encryption) means and on traffic interception, and for paying any taxes and duties that may be due in that country.

14.5. The Offer is drawn up in Russian. Translations into other languages are for information only; in the event of any discrepancy between the Russian version and a translation, the Russian version prevails.
