Keploy generates API tests and stubs from real production traffic, catching regressions without writing test code.
Keploy is an open-source testing platform that records real API traffic and converts it into test cases and mocks automatically. Developers get regression suites that reflect actual usage, plus AI-generated edge cases that humans tend to miss. It works across languages and frameworks without code changes, integrates with CI pipelines, and uses production-traffic digital twins to make testing safe and realistic.
Keploy’s recording approach sidesteps the classic testing bottleneck: instead of writing tests for hypothetical behavior, it captures what production actually does, then replays it safely against isolated dependencies. Teams report large jumps in coverage without adding test code.
The digital-twin approach also simplifies flaky-test problems: recorded dependencies replay deterministically, removing network variability. Teams adopting Keploy typically start with their most painful integration suite and expand from there.
Keploy’s core is free and open source. Hosted plans add AI test generation, team features, and enterprise support.
Backend teams that ship frequently and want regression coverage without the cost of hand-writing integration tests.
Yes, the open-source version is free; the hosted platform charges for advanced AI and team features.
Keploy integrates through its CLI and agents into CI pipelines; the platform exposes APIs for enterprise workflows.
Unlike traditional test frameworks, Keploy derives tests from real traffic, so coverage reflects production behavior, not assumptions.
No, Keploy works as a wrapper or agent without modifying application source code.
Keploy is language-agnostic, supporting services written in Go, Java, Node.js, Python, and more.
Yes, AI-assisted edge case generation extends coverage beyond recorded traffic.
Yes, the core platform is open source with a hosted offering for teams.
Yes, service-level recording and mocks fit microservice architectures well.
Yes, CI integration makes recorded tests part of your regression gates.
No, recorded traffic can be captured safely in staging or production mirrors and replayed in isolated test environments.
