Build and test API endpoints without touching a backend. Define your routes, set your responses, and instantly get a working endpoint that returns real-looking data. No server setup, no configuration — just start building and let your frontend move at its own pace.

A clinic appointment system where patients book appointments by selecting a department and available doctor. Doctors can review incoming requests and accept or reject them. Admins manage the platform by adding or removing doctors, keeping up to date.

A real-time chat app where each conversation runs in an isolated room. Messages persist in MongoDB, so history loads on refresh. Auth is handled with HTTP-only cookies, and online presence plus typing indicators update instantly via Socket.io.

A student management system where admins and staff can add, update, and manage student records through a clean dashboard. Includes search and filter to quickly find students, with JWT-secured endpoints and role-based access to keep data protected.
