Collie

ColliePWA is an open source, self hosted web app that puts terminal coding agents on your phone. It mirrors agent panes running in a terminal multiplexer, with Herdr as the primary backend and experimental support for tmux and Zellij, so developers can see which agents are waiting, read the screen and reply from anywhere without installing anything from an app store. It is built for developers who leave Claude Code, Codex, OpenCode or pi running for long stretches on a desktop, home server or spare machine. The dashboard lists every pane grouped by workspace, with those that need input at the top. From the phone users can read output, reply by text or voice, send keystrokes through a keypad for Esc, Ctrl combinations and arrows, pick plan options, run configured quick actions and slash commands, search output beyond normal scrollback and attach images or code files. Push notifications fire when an agent asks a question, finishes, or its prompt cache is about to go cold, and each pane shows a cache countdown. Crews let several machines sit behind one URL, with a deputy taking over if the lead goes quiet. ColliePWA is free under the MIT license. It runs as a single user binary, installed with a shell script, and there is no paid tier. Security is local by design: the server binds to loopback, is reached over Tailscale or a custom ingress, and requires paired devices, with each write authorised by the paired device's token and no cloud intermediary involved.
