Beeceptor

Beeceptor is an HTTP proxy, made for the rest APIs. It intercepts HTTP requests for you to mock in real-time.

Use-cases

Mock a rest API / Fake an API
Customizable responses to simulate API response and failures.
Use this for load testing an API, without load testing the downstream APIs.
Simulate latencies and timeouts of downstream APIs (validate rarely reachable code paths)
A/B testing by switching API endpoints or versions without any redeployment. (prod code vs new code)
Don't block your UI devs when backend APIs are still in development. Just mock it!
Create webhook endpoints and simulate responses.
