Merge API documentation across iterations
Maintain API documentation inside each iteration, then merge into the project by microservice. Fewer gaps between services and less manual copy-paste when releases land.

Open-source API management for
microservices and delivery teams
ApiChain is a free REST client and API testing platform: keep API documentation with each iteration, automate microservice requests, and run database-backed assertions before you merge to production—without juggling separate tools.
API management built for real delivery workflows
One open-source app for API documentation, REST client debugging, automation testing, and regression across microservice APIs—so your team spends less time on glue work and more time shipping.
Repeatable API testing without brittle fixtures
Use built-in random strings, timestamps, and helpers to refresh test data automatically. Rerun the same automation testing flows every sprint without hand-editing payloads.
Database assertions alongside REST responses
Validate HTTP responses and query your database with SQL to confirm side effects. Pair API testing with real data checks and teardown steps that reduce stale test data risk.
Project-wide regression for microservice APIs
Export iteration suites into a shared project and run regression in one click. See how changes ripple across microservice APIs before you promote a release.
