API Echo

About

API Echo gives you a focused, distraction-free view of API calls happening on any page. No more digging through hundreds of network entries in DevTools just to find the API requests that matter.

What it does:
- Captures all XHR and Fetch requests automatically
- Displays requests in a clean, sortable table inside a new DevTools panel
- Color-coded HTTP methods (GET, POST, PUT, DELETE, PATCH) and status codes
- Shows request duration, response size, and timestamps at a glance

Powerful filtering:
- Search across URLs, headers, and request/response bodies
- Filter by HTTP method (GET, POST, PUT, DELETE, PATCH, OPTIONS, HEAD)
- Filter by status code range (2xx, 3xx, 4xx, 5xx)

Detailed request inspector:
- View request and response headers
- Formatted JSON with syntax highlighting (keys, strings, numbers, booleans)
- Timing waterfall showing DNS, connection, TTFB, and download phases
- Copy any request as a ready-to-use cURL command
- Copy response body to clipboard with one click

Privacy first:
- All processing happens locally in your browser
- No data is collected, stored, or transmitted
- No external servers or analytics
- No account required

Built for frontend developers who want a cleaner way to inspect API traffic without the noise of the full Network tab.
