Key Features
Simple Templates
Map keys directly to built-in Faker.js generators — person.fullName, internet.email — without schema verbosity.
Live Shareable URLs
Every endpoint is instantly accessible via a unique, permanent URL — share it with teammates or hit it directly from your frontend code.
Dynamic Query Params
Control array lengths, inject random seeds, simulate latency, and force arbitrary HTTP status codes — all via query parameters, no redeployment needed.
Request Validation
Optionally enforce a JSON Schema on incoming request payloads so your mock behaves exactly like a production API with strict validation.
Interactive Playground
Test every endpoint straight from the dashboard — tweak params, fire requests, and inspect live JSON responses in a built-in Monaco-powered inspector.
