Create a mock REST API in minutes
Define endpoints and JSON responses in a visual editor. Your API goes live at a public URL the moment you save.
Any method, any path
GET, POST, PUT, PATCH and DELETE with path parameters like /users/{id}.
Dynamic responses
Use placeholders such as {{params.id}}, {{uuid}} and {{random.email}} to return realistic data.
Simulate real conditions
Set status codes, custom headers and artificial delays to test loading and error states.
Share with your team
Protect with API keys, restrict origins and IPs, and review every request in the log.
