Describe an API in plain words or paste an OpenAPI spec. MockAI returns realistic REST endpoints on a sandbox URL you can call right away — with latency, errors and auth you control.
A local preview of the response templating engine. Sign in to generate real, hosted endpoints from the same prompt.
Runs in your browser. No account needed.
Built for frontend work that cannot wait on a backend.
Describe the API in plain words. You get routes, status codes, query params and Faker-backed response templates.
Paste openapi.yaml or swagger.json. Schemas are converted to dynamic mock responses, matching routes updated in place.
Inject latency, force a random error rate, cap the rate limit, require a bearer token. Test the unhappy paths on demand.
Every call to your sandbox is recorded: method, path, status, latency, headers and body — readable live from the console.
Each project gets its own reachable prefix. Point your frontend at it and drop the fixtures from your codebase.
Invite by email, share every project in the workspace, and decide who does what with owner, admin and member roles.
