Instant Mock API
Design a resource, get a live REST endpoint in seconds - serving realistic fake data with pagination, filtering, sorting and search. Perfect for prototyping a front end before the real backend exists. No signup, and the same mock always returns the same data.

How it works
When you create a mock, the server stores only your schema - never the data. Each response is generated on demand from a seed derived from your mock's id, so the dataset is fully deterministic: the same record always has the same values, yet nothing sits in a database. The API supports real querying (?page, ?limit, ?sortBy, ?order, ?search, and equality filters on any field), plus simulated POST/PUT/PATCH/DELETE that echo back like JSONPlaceholder. CORS is wide open, so you can call it from any app.
It's part of a suite of developer tools on this site, all served by the same documented API - you can browse the live docs.
