Use Keploy to capture real API paths and build repeatable tests around behavior that already matters.
Skip if your service interfaces are not stable enough for recorded tests to stay useful.
Keploy can reduce the work needed to test APIs that depend on databases and external services.
Skip if your test strategy requires fully hand-authored acceptance scenarios only.
Captures API calls and dependencies, then converts them into repeatable test cases that reflect real system behavior.
Creates mocks from recorded dependencies so tests can run without every external service or database path live.
Fits backend CI workflows where recorded tests should catch behavior changes before deploy.

Keploy records API traffic and dependencies, then generates test cases and mocks for regression testing.
Local-first API client for HTTP, REST, and GraphQL
AI-powered CLI for automated API testing with natural language
Open source Postman alternative for REST and GraphQL testing
Local-first API client for HTTP, GraphQL, and WebSocket
A coding agent that lives in your terminal.
Run repeatable multi-step coding workflows from CLI or desktop
Backend teams know they need regression tests, but writing and maintaining them by hand is slow. API behavior changes across services, databases, queues, and third-party calls, and mocks drift away from how the system behaves in production.
The result is a testing gap: teams either ship with too little coverage or spend heavy engineering time updating test fixtures after every integration change.
Keploy and Postman both touch API testing, but they start from different workflows. Postman is a request client and collaboration platform; Keploy records real traffic and turns it into regression tests and mocks.
Keploy is better when the goal is automated backend regression coverage from existing behavior. Postman is still better for exploratory API calls, documentation, and manual team collaboration around collections.
Postman is a broad API client and collaboration platform. Keploy focuses on turning real backend traffic into automated tests and mocks.
