FlameWM
A window manager and desktop shell for Linux, written in Rust, with its UI in HTML and CSS compiled to native code.
Extremely efficient. Two sessions: X11 and Wayland.

Why FlameWM
- Native and small. The shell is HTML and CSS, compiled at build time. There is no embedded browser. Idle figures are in Performance.
- One desktop, one owner per job. The window manager, shell, settings, lock screen and apps are separate crates. The layering rules are in
docs/ARCHITECTURE.md.
- Honest status. Open work is tracked in
docs/TODO.md. Known issues are listed below, not hidden.

The screenshots come from an isolated FlameWM session on a private Xvfb display, with the default wallpaper, sample files and a neutral profile.
Features
Status key: Shipped is in the current source and used in the screenshots. Partial is present with stated gaps. Planned is not yet built.

Status
FlameWM is a source-level release. It does not claim parity with the historical IceWM or C implementations. Release history is in CHANGELOG.md. The current version is printed by ./scripts/version.
Both sessions are supported. The Wayland session is owner-reported working on a real laptop; that report is not re-verified by CI or in the build sandbox. See docs/INSTALL.md and docs/PACKAGING.md.
Sessions
| Session | Entry | Notes |
|---|
| FlameWM (X11) | /usr/share/xsessions/flamewm.desktop | Default. |
| FlameWM (Wayland) | /usr/share/wayland-sessions/flamewm-wayland.desktop | Native DRM/KMS. A nested window backend exists for testing inside another session. |
The Wayland compositor is crates/flamewm-wm-wayland, built on Smithay. It runs native Wayland clients and XWayland. The shell, desktop and settings run as XWayland clients. Install from a working X11 session first. If the Wayland session fails, choose FlameWM at the login screen. The wrapper does not fall back to X11 by itself.
