Beeceptor

Beeceptor is an API mocking service. It helps you mock a hosted rest API and manipulate responses with rules.

Create a mock of an existing rest API in seconds. Route traffic via proxy, record the requests/responses and replay with rules. Customizable responses to simulate API response and failures.
Fastest way to build fake API endpoint without any coding.
Use this for load testing an API, without load testing the downstream APIs.
Simulate latencies or slow-responses, and timeouts of downstream APIs. This helps in validating rarely reachable code paths in upstream APIs.
Switching the target API endpoints anytime. Compare two versions without any redeployment or coding. E.g. how does production or shipped code behave vs the new code.
Don't block your UI devs when backend APIs are still in development. Just mock it!
Create webhook endpoints and inspect the payloads send via other services.
