Why Flounder
Atomic & rollback-safe
Built on bootc: image-based updates that apply in one transaction and roll back just as cleanly.
Homebrew baked in
Thousands of CLI tools and fonts a `brew install` away — no layering, no rebuilds.
Flathub by default
Full Flathub access out of the box. Install any Flatpak on the net, instantly.
Images & flavors
Pull any flavor directly, or rebase an existing bootc system onto it.
