Keploy
Generate API tests and mocks from real traffic
Keploy is profiled here as a Testing tool for engineering teams. Read about features, pricing, and how it compares to related options in the tools directory.
Description
Keploy is an open-source testing toolkit that records live application traffic and turns it into test cases and data mocks. By capturing real API calls and their database interactions, it builds regression suites without anyone hand-writing them, which suits services where coverage lags behind the code. An AI layer extends the recorded cases into edge scenarios, and the recorder runs as a sidecar next to the application. By deriving suites from observed behavior, it gives services with thin coverage a starting test base that mirrors real production usage. The recorded mocks also let those tests run without live dependencies in continuous integration.
Key Capabilities:
Traffic capture that converts API calls into regression test cases
Automatic data mocks and stubs for dependencies like databases
AI-generated edge cases that extend recorded suites
Deduplication so redundant captured tests are filtered out
CI integration with GitHub Actions, Jenkins, and GitLab
Language-agnostic recording with support for Go, Node.js, Python, and Java
