blit

Terminal multiplexer and experimental Wayland compositor for browsers and AI agents. Nothing to configure, no required dependencies.

We publish a computer agent skill.

Try it now — no install needed:

docker run --rm grab/blit-demo

Or install and run locally:

curl -sf https://install.blit.sh | sh
blit open # opens a browser

Share over WebRTC:

blit share # prints a URL anyone can open

Manage named remotes and connect to them:

blit remote add rabbit ssh:rabbit          # save a named remote
blit remote add prod ssh:alice@prod.co     # another one
blit remote list                           # show all remotes
blit remote set-default rabbit             # make rabbit the default

blit open                                  # local + all configured remotes
blit terminal list                         # lists terminals on rabbit
blit --on prod terminal list               # one-off override
blit --on ssh:newhost terminal list        # full URI also works

The default remote is stored in ~/.config/blit/blit.conf as blit.target = rabbit and can also be set via the BLITTARGET environment variable. Named remotes are stored in ~/.config/blit/blit.remotes (mode 0600). blit open reads this file and shows all remotes in the browser's Remotes dialog (Cmd+K). SSH remotes are auto-installed on first connection.

Forward ports to whatever the server can reach — ssh -L over any blit transport, plus UDP:

blit forward 8080:localhost:3000                # local 8080 → server's :3000
blit forward 8080:localhost:3000 5432:db:5432    # a list, over one connection
blit forward udp/5353:resolver.internal:53       # UDP too
blit forward add web 8080:localhost:3000         # remember it
blit forward --all                               # start every saved forward

Listeners bind to loopback unless you name a bind address. The relay reaches whatever the server reaches; restrict it with blit server --allow-forward 'host[:ports]'. Saved forwards live in ~/.config/blit/blit.forwards (mode 0600). See docs/design/net.md.

Control terminals programmatically:

blit terminal start htop # start a terminal, print its ID
blit terminal show 1     # dump current terminal text
blit terminal send 1 q   # send keystrokes

Run GUI apps — on Linux, every terminal includes an experimental headless Wayland compositor:
