Jelly

A web terminal for your own servers. Open a project on your phone or computer, run Codex or Claude Code, and come back to the same session later.

• Persistent sessions. Closing the tab or restarting Jelly keeps your shells running.
• Local and SSH projects. Remote servers only need SSH, a POSIX shell and tmux.
• Phone-friendly input. Touch scrolling, Unicode input and a floating keyboard for key combinations.
