Cosmil 1.0 launched with a gorgeous interface and real performance problems. So I rewrote it. New Svelte 5 frontend, Rust backend—now a folder of 40,000 files now opens instantly. Multi-pane layouts (dual, tri, quad — as many as your screen fits), real cut and paste, workspace restoration, advanced search filters, native icons, all the Finder annoyances fixed, and more. Same interface people bought it for, none of the jank. No telemetry, no subscription — one payment, free updates forever.

The Finder alternative from the future. An all new file explorer with a beautiful customizable appearance, new features, and a flexible, intuitive interface.
