HTTP Lens
Network request debugger for HTTP and GraphQL
A Chrome DevTools extension that captures, analyzes, and provides deep inspection tools for all HTTP and GraphQL network traffic. Debug requests with formatted JSON trees, replay calls, diff responses, and export as cURL or HAR — all from a dedicated DevTools panel.
Features
Everything you need, built right in.
Real-time Network Capture
Captures all HTTP and GraphQL requests in real-time with auto-detection of GraphQL operations, displaying method badges, status codes, and domain info.
GraphQL Intelligence
Automatically detects GraphQL operations, extracts operation names, formats queries with variables, and includes a full introspection schema viewer.
Request Diffing
Select any two requests and compare headers and bodies side-by-side with color-coded diffs to quickly spot differences.
cURL & HAR Export
Copy any request as a ready-to-paste cURL command or export your entire capture session in HAR format for sharing and analysis.
Request Replay
Re-send any captured request with its original headers and body, then inspect the new response — all without leaving DevTools.
Advanced Filtering
Filter by URL, operation name, domain, HTTP method, status code, and request type. Include or exclude specific domains with precision.
