Your editor,
your layout.

Kosmos is a Linux-only code editor where every view is a tab you can place anywhere. Split panes in any direction, rearrange freely, and switch between workspaces without losing a thing.

Everything is a tab.

No fixed sidebars. No locked panels. File trees, terminals, previews, and settings all live as tabs, so you can put them where they make sense.

Flexible Layouts

Split panes horizontally, vertically, or nest them however you want. Drag any tab into any pane. Your workspace adapts to your workflow, not the other way around.

Persistent Workspaces

Switch between projects instantly. Kosmos restores your layout and editor state right where you left them, while terminals can keep running.

Native Performance

Built in Rust with GPUI for a fast, native interface. Kosmos stays responsive while managing complex layouts, terminals, previews, and editors.

Open source. MIT licensed.
