ReqCraft - HTTP Request & Mock Tool

Intercept, redirect, rewrite REST API endpoints, mock request/response bodies, and modify HTTP headers with ease.

ReqCraft is an all-in-one network debugging and API simulation extension built for modern frontend developers, QA engineers, and backend teams. KEY CAPABILITIES: ✓ Rewrite REST API URLs: Proxy staging and production requests to your local development environment (e.g. localhost:3000) with dynamic path parameters. ✓ Redirect Requests: Forward URLs using Wildcard and Regular Expressions. ✓ Mock Responses: Instantly return custom status codes (200, 404, 500) and mock JSON payloads without waiting for backend implementations. ✓ Override Request Payloads: Modify outgoing POST, PUT, and PATCH bodies on the fly. ✓ Header Customization: Set, append, or strip Request and Response headers to easily inject auth tokens or bypass CORS limits. ✓ Environment Profiles: Group and toggle rules across development, testing, and production workflows. ✓ JSON Export & Import: Back up and share rule sets across your entire team.
