Keploy generates API tests and stubs from real production traffic, catching regressions without writing test code.

Overview

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.

Key Features

  • Test generation from recorded API traffic
  • Automatic mock/stub creation for dependencies
  • AI-suggested edge cases beyond recorded flows
  • Language- and framework-agnostic instrumentation
  • CI/CD integration for regression gating
  • Open-source core with hosted platform options

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.

Pricing

Keploy’s core is free and open source. Hosted plans add AI test generation, team features, and enterprise support.

Who Is It For

Backend teams that ship frequently and want regression coverage without the cost of hand-writing integration tests.

FAQ

Is Keploy free to use?

Yes, the open-source version is free; the hosted platform charges for advanced AI and team features.

Does Keploy offer an API?

Keploy integrates through its CLI and agents into CI pipelines; the platform exposes APIs for enterprise workflows.

How does Keploy compare to alternatives?

Unlike traditional test frameworks, Keploy derives tests from real traffic, so coverage reflects production behavior, not assumptions.

Does Keploy require code changes?

No, Keploy works as a wrapper or agent without modifying application source code.

Which languages are supported?

Keploy is language-agnostic, supporting services written in Go, Java, Node.js, Python, and more.

Can Keploy generate edge cases?

Yes, AI-assisted edge case generation extends coverage beyond recorded traffic.

Is Keploy open source?

Yes, the core platform is open source with a hosted offering for teams.

Is Keploy suitable for microservices?

Yes, service-level recording and mocks fit microservice architectures well.

Does it work with CI?

Yes, CI integration makes recorded tests part of your regression gates.

Does Keploy need access to production?

No, recorded traffic can be captured safely in staging or production mirrors and replayed in isolated test environments.
