Relay – Intercept Modify

Relay is an open-source Chrome extension that lets you capture, edit, and test HTTP requests directly in your browser. No account needed—just install and start using.

Key Features 🔧
Capture HTTP Traffic in Real Time 📡
Relay intercepts HTTP and HTTPS requests as you browse, making it easy to filter by method (GET, POST, etc.) or URL so you only see the requests that matter.

Modify Requests Instantly ✏️
Edit every aspect of a captured request, from the base URL and HTTP method to headers, query parameters, and body content. You can even adjust response details for flexible testing.

Run API Requests in the Browser ⚡
Send and test API requests directly in your browser with immediate feedback—no need for external tools. You can also export requests as cURL commands if you need them for other uses.

Save Your Sessions 📂
Organize and revisit your sessions, so you can easily review and analyze past requests when needed.
