#4 [Roadmap] macOS / Linux port via Avalonia

[Anonymous]

Originally created by: phantasmat2018

Status: Planned, contributor-friendly.

The Windows app uses Win32 APIs that have no cross-platform analog in .NET:

• RegisterHotKey - global hotkeys
• SendInput - synthesized Ctrl+C / Ctrl+V
• Windows Credential Manager - encrypted API key storage
• H.NotifyIcon - tray icon

A cross-platform port would require:

• UI: Avalonia (XAML-compatible alternative to WPF, cross-platform)
• Hotkeys: SharpHook or platform-specific (X11 XGrabKey on Linux, Carbon EventHotKey on macOS)
• Tray: Avalonia.Controls.TrayIcon
• Credentials: keyring on Linux, Keychain on macOS, DPAPI on Windows - abstraction over ICredentialStore
• Clipboard: Avalonia's IClipboard

Essentially a from-scratch rewrite of the chrome (UI + platform integrations); business logic (Services/TextProcessor, prompt management, LLM clients) stays portable.

For contributors

If you have Avalonia experience or macOS / Linux desktop dev background and want to take this on - please comment. Happy to chat about architecture and split coordination work.

Acceptance (when started)

• [ ] Separate repository capy-bro-avalonia (avoid mixing WPF-specific code)
• [ ] Feature parity with Windows: hotkey, prompts, history, providers
• [ ] CI builds for all 3 platforms
