cornercase is a terminal multiplexer for running coding agents in parallel. Every agent gets its own git worktree and tab. The sidebar shows which are working, waiting or done, and the diff sits next to each one. Free and open source, Linux and macOS. usecornercase.dev

Starting ten coding agents is easy. Keeping up with them is the hard part. cornercase is a terminal multiplexer built for that. It runs inside the terminal you already use, over SSH too. Free and open source, Linux and macOS. What it does, in five posts:

4. Close the window. Nothing stops. A background server owns the shells. Run cornercase again to reattach, from any terminal or from your phone over SSH. Or keep the agents on a bigger machine with cornercase remote <host>.

5. Everything is also a command, so one agent can run the others: cornercase start claude --worktree fix-login --prompt '...' cornercase wait --pane $pane cornercase read --pane $pane --last-message Rust, MIT or Apache-2.0. github.com/usecornercase/cor…

La gracia de @usecornercase es que es un server que corre detrás y puedes engancharle lo que quieras. Ahora mismo estoy haciendo pruebas con GPUI pero podría ser otra electron, tauri o lo que sea. A la izquierda es la TUI de cornercase y a la derecha la prueba con GPUI.

New in cornercase: stage or discard a file from the changes panel. Hover a file. + stages it, ↺ restores it to the last commit. If an agent changed the file after the panel showed it, nothing happens and a message says so. From a script: cornercase changes stage PATH

GPUI es una maravilla, estuve probando cositas haciendo una prueba de versión desktop de cornercase y nada que ver con Electron. Qué rapidez.
