SplashSplash over SSH
Agents on your workstation. Splash in any browser.
Run splash-server on the machine that has your repositories and agent logins, then open it through an SSH tunnel. Files, git, terminals and agents stay together on that machine. Close the laptop; the agents keep working.
Start the server where the code lives
No window or display needed. Install and sign in to your agents on the same machine.
splash-server --name devbox ~/code/my-project Tunnel to it from your laptop
The server listens on loopback only. SSH carries the browser connection.
ssh -N -o ExitOnForwardFailure=yes -o ServerAliveInterval=30 \
-L 127.0.0.1:4780:127.0.0.1:4780 devbox Sign in with the token
Open http://127.0.0.1:4780 and paste the token from the server's server.token. Startup prints where the file is, never what's in it.
Built for flaky connections
Reconnects without surprises
When the tunnel returns, Splash refreshes sessions, the open transcript, permissions, files and terminal views.
Drafts stay put
Unsent text stays in the open tab and sending is disabled while offline. Commands are never replayed automatically, because a failed response doesn’t prove the server missed them.
Loopback and a token
The server binds to loopback and requires a token. Login uses an HttpOnly, SameSite cookie; foreign origins and non-loopback Host headers are rejected.
Keep it running
A systemd user service ships in packaging/server/, with a launchd example for macOS. Several hosts can use different local tunnel ports.
mkdir -p ~/.config/systemd/user
cp packaging/server/splash.service ~/.config/systemd/user/
systemctl --user daemon-reload
systemctl --user enable --now splash Full setup, including the launchd example and rotating the token, is in the README.
