keploy
Open-source platform for creating safe, isolated production sandboxes for API, integration, and E2E testing.
Open source tools like Keploy help streamline this process by creating stable, deterministic test cases and mocks, reducing external dependencies and human error. In modern testing environments where CI/CD pipelines are the norm, reducing test flakiness should be a top priority. Not only does it ensure trust in your automation suite, but it also boosts confidence in every release, leading to better software and happier users.
