Requestly

Requestly is a comprehensive developer toolkit designed to streamline the entire API lifecycle, from initial development and testing to debugging and frontend integration. It combines a powerful API client with an unmatched HTTP interceptor and robust mocking capabilities, all within a unified, lightweight platform. This integrated approach eliminates the need to juggle multiple disparate tools, allowing developers and teams to build, inspect, and refine their web applications and APIs with unprecedented speed and control.

API Client & Playground

At its core, Requestly offers a seamless API Client experience that accelerates development and collaboration. It provides a clean workspace for crafting, organizing, and executing requests.

✨ A full-featured API Playground for interactive testing and exploration.
🎯 Organized API Collections to keep your endpoints structured and accessible.
🤝 Local & Team Workspaces for smooth collaboration across projects.
🔬 Built-in API Tests to validate behavior and ensure reliability.
🔄 Easy import from popular tools like Postman & Bruno to migrate your workflow effortlessly.

HTTP Interceptor & Debugging

Requestly's HTTP Interceptor is a game-changer for debugging web applications. It acts as a proxy, giving you the power to inspect and manipulate network traffic in real-time, directly from your browser.

✨ Redirect URLs or Switch Domains to test different environments or staging servers.
🎯 Modify API Responses, Request Bodies, HTTP Headers, and Query Parameters on the fly.
🔧 Insert Custom Scripts to inject logic or alter page behavior dynamically.
⏱️ Delay Requests to simulate poor network conditions and test loading states.
🚫 Block Network Requests to understand dependencies and improve performance.
📱 Enable Cross-Device Testing by sharing session rules across your ecosystem.

API Mocking & Frontend Development

To build the frontend fast, independent of backend availability, Requestly provides sophisticated API Mocking. Developers can simulate complete API endpoints with custom responses, status codes, and headers. This decouples frontend and backend workstreams, enabling parallel development and allowing teams to prototype user interfaces, test edge cases, and demonstrate features without waiting for live APIs to be ready.
