Create an unlimited number of mock API with unlimited number of routes and run them in parallel. Use the CLI to run your mock APIs in any headless or automated environment: CI, GitHub Actions, Docker containers, etc. Mock API import / export with Swagger/OpenAPI format support. Route regex supported (/.*, /[a-z]{3}, ...), based on ExpressJS syntax. Serve multiple rules-triggered or random responses with any headers body, or HTTP status codes. Serve your mock API over TLS with self-signed certificate. Add any response headers to your routes and mock API. With auto-completion. Add latency at environment or route level or even both. All incoming requests and outgoing responses are logged for easier debugging. Redirect all non-defined routes to the specified host with Mockoon's proxy mode. File serving with automatic mime type detection and templating support. Rich text editor for body content supporting multiple languages (JSON, HTML, etc). Templating supported in body, file content and header, with many helpers: url params, query params, JSON body lookup, etc. Real-time auto save as you type. Never worry again about saving! Run the CLI directly as an NPM package or use the provided Docker image. No account, no sign-up, no cloud deployment required.
