Development Roadmap ​

Goal: Build a desktop application using Tauri, enabling developers to expose local servers via .local domains and public URLs, with traffic inspection capabilities.

Phase 1: MVP - Local Domain Proxy 🚀 ​

  • [x] Setup Tauri Workspace
    • Initialize Tauri with Svelte, TypeScript, and Vite using Bun.
    • Configure TailwindCSS (or similar) for UI.
  • [x] Local Proxy Engine (Rust)
    • Implement a reverse proxy server (using pingora, hyper, or axum).
    • Bind to port 80 (requires admin privileges).
    • Forward traffic from myapp.local -> localhost:5173.
  • [ ] DNS / Host Resolution
    • Modify /etc/hosts to map myapp.local -> 127.0.0.1.

Phase 2: Traffic Inspector 🔍 ​

  • [ ] Request/Response Capture
  • [ ] HTTPS / TLS Support
    • Generate a local Root CA.
    • Dynamically generate certificates for user-defined domains.
    • Install/Trust Root CA in the system keychain (security command).

Phase 3: Traffic Inspector UI 🔍 ​

  • [ ] Request/Response Capture
    • Implement middleware in the Rust proxy to capture HTTP metadata (Headers, Body, Status, Timing).
  • [ ] Real-time UI Updates
    • Stream logs from Rust to Frontend via Tauri Events.
    • Create a "Network" tab in UI similar to Chrome DevTools.
  • [ ] Replay Mechanism
    • Ability to resend a captured request from the backend.

Phase 4: Public URLs (Tunneling) 🌍 ​

  • [ ] Tunneling Client
    • Implement a tunneling client to expose local ports to the internet.
    • Architecture: Need a relay server (VPS).
    • Protocol: SSH Remote Forwarding, WebSocket Tunnel, or HTTP/2 Tunnel.
    • MVP: Use an existing open-source tunnel solution (like rathole or similar) embedded or re-implemented.

Phase 5: Advanced Features & Polish ✨ ​

  • [ ] Privileged Helper Tool
    • Separate binary to handle root-level tasks (binding port 80, editing hosts) to avoid repeated password prompts.
  • [ ] Persistent State
    • Save configurations to disk (SQLite or JSON).
  • [ ] Tray Icon
    • Quick access to start/stop services.

Technical Stack ​

  • Frontend: Svelte, TypeScript, TailwindCSS, Vite.
  • Backend (Tauri): Rust.
  • Proxy: hyper / tower / pingora.
  • State Management: React Query / Zustand.
