This repository is an unofficial, community-maintained Microsoft Teams desktop client for Linux (and cross-platform). It wraps the Microsoft Teams web application in an Electron shell, providing native desktop integration features that the web client lacks on Linux, such as system tray notifications, custom backgrounds, screen sharing with preview, WebAuthn/FIDO2 hardware security key support, MQTT integration for home automation, multi-account profiles with isolated sessions, and configurable themes. The architecture follows a typical Electron main/renderer process split with heavy use of IPC for communication. The main process manages windows, configuration, menus, tray, auto-updates, and integrates with system services (D-Bus for KDE/GNOME, Flatpak portals, Snap confinement). The renderer process uses preload scripts to inject browser tools that intercept WebRTC constraints, monitor DOM mutations, and patch Teams' internal React services for features like meeting start detection, speaking indicators, and token caching. The codebase is well-structured with a modular design, extensive unit and E2E tests, automated CI/CD pipelines, and formal architecture decision records (ADRs). It is actively maintained with frequent releases, responsive issue triage, and a strong focus on Linux compatibility, though it also supports Windows and macOS.
