Debug
Understand what's happening under the hood. Timing breakdowns, connection details, headers, and sizes - everything you need to diagnose and optimize your API calls.
Millisecond Precision
Every phase of the request lifecycle measured and visualized. Know exactly where time goes.
Security Insights
TLS version, HTTP protocol, security headers - verify your connections are secure.
Size Monitoring
Track payload sizes across requests and responses. Catch bloat before it becomes a problem.
Timing Breakdown
See exactly where time is spent in every request. From DNS lookup to TLS handshake, from server response to download - every millisecond is accounted for. Identify bottlenecks instantly with the visual waterfall chart.
Size Analysis
Monitor request and response sizes down to the byte. See how much data your headers contribute versus your body. Optimize payload sizes and catch unexpected bloat before it affects performance.
Headers Inspector
Examine every header sent and received. Content-Type, Cache-Control, Security headers, CORS - everything is organized and searchable. Understand exactly what your server is telling you.
Connection Details
Deep dive into the connection layer. See TLS version, HTTP protocol (HTTP/1.1, HTTP/2, HTTP/3), resolved IP address, and DNS cache status. Everything you need to debug network-level issues.
What You Can Debug
Timing Phases
- DNS Lookup, TCP Handshake
- SSL/TLS Handshake time
- Server Response (TTFB), Download
Connection Info
- HTTP/1.1, HTTP/2, HTTP/3 protocol
- TLS version (1.2, 1.3)
- Resolved IP, DNS cache status
Headers
- Request and response headers
- Security headers (CSP, CORS, etc.)
- Caching headers (Cache-Control, ETag)
Size Metrics
- Request headers and body size
- Response headers and body size
- Total transfer size
