MockBolt

Developers building frontends, writing integration tests, or testing webhooks often need a working API endpoint before a real backend exists or without touching production. Setting this up conventionally requires signup, installation, or configuring a server just to return canned responses, check how an app handles slow or failing backends, or inspect incoming webhook payloads from services like Stripe or GitHub. That setup overhead slows down frontend work, test writing, and webhook debugging.

MockBolt lets a user paste any JSON and immediately get a live public HTTPS mock API endpoint, with no signup, email, or install. It supports all major HTTP methods (GET, POST, PUT, PATCH, DELETE) configurable per endpoint, custom status codes from 100 to 599, custom response headers, simulated latency up to 10 seconds, simulated request failures, and conditional or round-robin responses based on query parameters or headers. A live request inspector shows the body, headers, query params, IP, and timing of every request hitting the endpoint, and open CORS makes it callable directly from browsers, mobile apps, emulators, or CI. Developers use it for frontend development against real endpoints, integration testing, webhook payload inspection, and load testing without touching production.
