Features
From traffic to answers.
Everything follows the real debugging loop: capture first, isolate the request, then replay or rewrite it. No account. No cloud console.
Dynamic certificates and HTTPS
Issue certificates on demand. Create, install, export, or reset the Oxypaw Root CA without leaving the app.
Inspect and replay
Read complete requests and responses, then replay any captured request directly from session history.
Traffic rules
Control traffic with Block, Allow, and Map Remote. Map Local and Breakpoint are ready in the rules workspace.
Local session storage
Sessions and rules stay in a local SQLite database. Search and review traffic without a cloud account.
A native desktop workspace
Built with Tauri 2, Rust, and React for a focused three-pane workflow that stays fast under real traffic.
Workflow
