Compose a full mock API response - status code, headers, JSON body - and copy as a fetch handler, MSW handler, or curl command.
This api mock response generator runs 100% in your browser. Nothing you paste, drop, or generate ever leaves your device - no analytics on your input, no uploads, no logs.
MSW handlers, fetch wrappers, or curl scripts in your tests.
Same browser-only philosophy. Free, no signup, no upload.
Send GET/POST/PUT/PATCH/DELETE requests with headers and JSON body.
Generate realistic fake JSON for tests, mocks, and seed data.
Generate a curl command from URL, method, headers, and JSON body.
Beautify, validate, and minify JSON with sortable keys, exact error positions, and a one-click copy.
Validate JSON syntax with exact line and column for every error.
Strip whitespace from JSON to produce a single compact line.
