Debug anything.
Capture, inspect, and replay HTTP/HTTPS traffic. Debug web APIs, reverse-engineer mobile apps, or let your AI agent query everything.
npx @rvanbaalen/roxyproxy Intercept Every Request
Your dashboard makes 47 API calls on load. Three of them fail intermittently. RoxyProxy captures every request with full headers, body, and timing. Filter by status, method, or path to find the culprit in seconds.
Read docs: CLI Reference →HTTPS Interception
That iOS app doesn't have public API docs. Point your device at RoxyProxy, trust the CA, and watch every encrypted request in cleartext. See exactly what endpoints it hits, what tokens it sends, what data it returns.
Read docs: HTTPS Setup →AI Agent Integration
Tell your AI agent "the user update endpoint returns 422." It queries RoxyProxy, inspects the request body, sees the validation error, fixes your code, replays the request, and confirms the fix. You watch.
Read docs: AI Agent Plugin →Request Replay
Captured the failing request in staging. Replay it against your local server with one command. Modify headers, change the body, hit it again. Iterate until the fix works without touching the frontend.
Read docs: API Reference →Built for developers. Ready for AI agents.
Every captured request is available through a visual web dashboard for manual inspection and a structured CLI for AI-powered debugging. Same data, your choice of interface.
Web Dashboard
Real-time traffic streaming, sortable columns, host and status filters, and a detail panel showing full headers and response bodies. Grab a captured request and send it to the Repeater to edit and resend it. Proxy state syncs live between the dashboard and CLI.

CLI + AI Agent Plugin
Query captured traffic from the command line or let your AI coding agent do it. The --format agent flag returns structured JSON your AI can parse, diagnose, and act on without switching context.
