API Echo

See API calls as they happen. A clean, focused view of XHR and Fetch requests with formatted responses for developers.

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.
