Transparent proxy for debugging network traffic
Mark complete to track your learning progress.
Route and inspect network traffic through a transparent proxy for debugging API issues.
Rust Proxy is a high-performance transparent proxy for inspecting HTTP/HTTPS traffic between your tools and external services. It sits between clients and servers, logging requests and responses without modifying them.
When debugging network issues with AI APIs or other services, Rust Proxy lets you see exactly what's going over the wire without changing your application configuration.
No app changes needed
TLS interception capable
Minimal overhead in Rust
Headers, bodies, timing
Start the proxy and route traffic through it.
# Start the proxy on default portrust_proxy start# Start on a specific portrust_proxy start --port 8080# Route curl traffic through the proxyHTTPS_PROXY=http://localhost:8080 curl https://api.example.com# View captured trafficrust_proxy logs
HTTPS_PROXY environment variable to route any tool's traffic through the proxy.Common situations where Rust Proxy helps.
# Debug API authentication issuesHTTPS_PROXY=http://localhost:8080 claude "hello" 2>/dev/nullrust_proxy logs --last 1 --headers# Measure API latencyrust_proxy logs --timing# Filter by domainrust_proxy logs --domain api.anthropic.com
A standard GET request passes through the proxy transparently. No modifications, no blocks - just logged for inspection.
