Production traffic turned into API and integration tests
Reviewed by the the30top research team · Last reviewed 2026-10-27
Overview
Keploy builds a digital twin of production behaviour from real API traffic, mocks and dependencies, then uses it to verify AI-written or human-written changes in CI. It generates API, integration and regression tests with AI, offers an open-source option, and integrates with VS Code, Slack and tools such as Postman and WireMock. A free Playground tier and a Pro plan are published, with limits on test suite generation and runs per month. It centres on backend and API testing, so UI-heavy teams will need another tool.
Our verdict
A strong, developer-friendly pick for API and integration testing. Confirm the exact Pro price and limits before budgeting.
