OpenAPI-First
All contracts start with OpenAPI specifications, ensuring clear API definitions from the beginning.
Entente
Contract based API testing. Build reliable APIs with confidence.
What is Entente?
Section titled “What is Entente?”Entente is a modern contract testing platform that combines OpenAPI specifications with real interaction recording to provide automated contract testing between services. It helps teams build reliable APIs with confidence.
Key Features
Section titled “Key Features”Automatic Recording
CI environments automatically record real interactions of a consumer against its mocks to replay against the actual provider service.
Smart Fixtures
Ability to record and store fixtures from one consumer to re-use in others, with centralised management and approval.

Providers verify against actual consumer usage, not just theoretical contracts.

Architecture
Section titled “Architecture”Entente follows a TypeScript-first functional programming approach with a pnpm workspace monorepo structure:
- @entente/consumer - Consumer testing library
- @entente/provider - Provider verification library
- @entente/fixtures - Fixture management utilities
- @entente/cli - Command line interface
- @entente/server - Central service with Hono API + React UI
