How it works
Name your project
Give it a name. We generate a unique slug and your base API URL is ready.
POST /api/projects
→ { slug: "my-store-api-x7k2" }Add endpoints
Pick a method, set a path, write your JSON response. Add delays to simulate real latency.
GET /products → 200 POST /orders → 201 DELETE /users/:id → 204
Use your live URL
Your mock API is live. Copy the URL, drop it in your frontend. Zero deploy, zero config.
fetch('https://mockapi.dev
/api/mock/my-store-api-x7k2
/products')Built for developers who ship fast
Any JSON shape
Arrays, nested objects, dynamic fields — write the exact response your frontend expects.
