Hosted API Mocking
Built for Modern Devs
Stop blocking frontend developers or hardcoding temporary JSON data. BuildIt lets you define custom endpoints, simulate latency or error codes, and generate mock data with AI instantly.
The Fastest Way to Mock REST APIs and Unblock Your Team
Stop sharing JSON files over Slack or hardcoding mocks in your repository. BuildIt handles hosting, latency simulations, and versioning.
Zero Local Setup
Get a live HTTPS URL in 10 seconds. No local config files, no local packages, and no node_modules bloating.
AI Response Generator
Type a brief prompt like 'e-commerce shopping cart' and get complete, realistic mock JSON data instantly.
Live Request Inspector
See every request hitting your mock — method, query, headers, and body. Debug frontend calls in real-time.
Everything You Need to Mock APIs Seamlessly
Features designed to match production API behaviors so your frontend looks, feels, and behaves like the real thing.
Mock Endpoint Builder
A clean visual editor to configure GET, POST, PUT, PATCH, DELETE paths, headers, and status codes.
Live Hosted URLs
Instantly get a public, shareable mock API endpoint accessible from curl, frontend applications, or QA test runner scripts.
AI Response Creator
Describe the schema in plain English, and the integrated AI will generate a realistic, valid JSON payload in seconds.
Delay & Latency Simulation
Add custom response delays (up to 5000ms) to test loading states, skeleton screens, and timeout handling.

Their experiences speak louder than words
BuildIt completely unblocked our frontend team. We designed our API contract, mocked all the endpoints in 10 minutes, and kept coding while the backend team built the database.
Sarah Johnson
Lead Frontend Engineer at Canva
The AI schema generator is pure magic. I typed 'mock e-commerce shopping cart logs' and got a perfect mock payload in seconds. The delay simulator let us test all our loading skeletons before production.
Daniel Kim
CTO at NextLaunch
We decoupled our QA test runner suites from live staging APIs using BuildIt. The ability to return status codes like 401 Unauthorized or 500 Server Error dynamically is a lifesaver.
Emily Chen
QA Automation Lead at HubSpot
Local tools like Mockoon can't be shared easily, and Postman is bloated. BuildIt is exactly what we needed: quick, hosted, and shareable.
Raj Mehta
Frontend Developer at Zomato
The real-time request logs are phenomenal. I can see exactly what query params my frontend is passing without reading terminal logs.
Aisha Patel
Software Engineer at Swiggy
I prototype multiple web applications every month. BuildIt is my go-to tool for getting mock endpoints up and running instantly without writing server boilerplates.
