Mock Server

Serve canned responses for requests you mark as mocks — handy for developing a frontend against an API that doesn't exist yet, or demoing without a live backend.

Any request can act as a mock: open its Mock tab, check Enable mock response for this request, and set a status code, headers, delay (ms), and a response body. The tab shows the method + path (derived from the request's URL — {{var}} prefixes, host, and query string are stripped, e.g. {{baseUrl}}/users/:id?x=1 → /users/:id) that the mock server will answer for.

Click Mock Server in the topbar to open the mock modal, which lists every request with mocking enabled across all collections. Pick a port (default 5875) and click Start to launch a local HTTP server that answers each enabled mock at its method + path — :name path segments match any value, so /users/:id matches /users/42. Headers and body support {{variable}} interpolation against the active environment/globals. Click Stop to shut it down.

The route list is a snapshot taken when you click Start — if you enable/edit a mock while the server is already running, click Stop then Start again to pick it up.
