Coming soon

For x64 and ARM64 PCs.

Lumber for Windows is in review at the Microsoft Store. Once it's approved, you'll get it there or with winget.

For x64 and ARM64.

Other distributions

An AppImage, which runs on most distributions without installing anything and keeps itself up to date. Make it executable, then open it.
