Overview

Our mission is simple: to build an open platform for simulating Payment Service Providers (PSPs).

By "open platform", we mean two things:

  • Hosting mock PSP APIs that are publicly accessible and open source.
  • Providing the tools you need to build and run custom mock PSPs.

We understand how complex and challenging it can be to mock PSPs. Drawing from our hands-on development experience, we are committed to delivering the right tools to simplify this process for you.

If you have any questions, suggestions, or even criticism, feel free to raise a Github Issue or click Contact the developer in any of our API documentation.

Typical Use Cases​

  • Testing payment orchestration services without relying on real PSP environments.

  • Automating CI/CD integration testing for payment flows and webhook handlers.

  • Mocking PSP backends for sales demos, customer onboarding, or product showcase environments.

  • Conducting training sessions and workshops that require predictable PSP behavior.
