Upload
Drop a file on the window. bateri asks where it should go, then sends it to your folder on the server.
The mockup terminal, now real.
The terminal everyone draws in their mockups: a command line with its own place at the bottom, a gliding caret, programs that survive a crash. This time, the GPU draws it.
A terminal that edits, remembers, and knows where you are.
The command line, now an editor.
The line you type sits at the bottom of the window: several lines, the mouse, a caret that glides.
Your programs keep running.
Updates, crashes, even ⌘Q: vim, your dev server and your ssh session are still there when bateri comes back.

Update “Install and Relaunch” ends nothing. A file transfer in progress makes the update wait.
Crash If bateri crashes or is force-quit, the same processes come back, with whatever they printed meanwhile below.
Quit With one setting, even ⌘Q ends nothing; a notification names what's still running. ⌥⌘Q ends them.
Where you are, always in plain sight.
On a server, in a database, inside a pod: the bar at the bottom says where you are. Production is red.

The machine's name, your remote folder and the server's load. Nothing to install on the server.
The server and database you're connected to — never your password. psql, mysql, sqlite3, redis-cli and mongosh.
The cluster's context, the namespace and the pod. docker and podman name the container you're in, too.
Which interpreter, from where: venv, conda, uv, pyenv, nvm… for Node, Ruby, Bun and Deno too.
After sudo -i or su the shell is red, whatever your marks say. A nested shell names itself too.
Splits as cards, moved by hand.
Hold ⌥⌘ and the panes lift: carry one beside another, or swap two. The program inside keeps running.
Files on the server, as close as Finder.
Preview
⌘-click a name in ls output and a read-only copy opens on your Mac.
Download
Drag a file or folder into Finder. It lands where you drop it.
Server load
CPU and memory sit in the status bar. Click for cores, disk, uptime and the busiest processes.
-
Everything clickable
Hold ⌘ and URLs, files and folders are underlined; ⌘-click opens them, right-click reveals them in Finder.
-
Zero idle frames
When nothing on screen changes, the GPU does nothing at all; your battery and fans notice.
-
International keyboards
Dead keys work, ⌥← ⌥→ jump by word, and ⌥-letters still type what your layout says.
-
Live settings
One TOML file that applies the moment you save. Or open the settings window with ⌘,.
Drawings
On paper first, then in Metal.
Every surface in bateri began as a written decision. See how a window is drawn, layer by layer.
