Collie
Collie is a mobile client for Herdr, tmux, and zellij that lets users monitor and reply to terminal agents.
ColliePWA is an open-source, self-hosted web app that mirrors terminal agent panes from Herdr, tmux, or zellij to your iPhone or Android phone. It allows you to read screens, send keystrokes, reply to interactive prompts, or use voice input transcription. The app groups workspaces into a single list and places panes requiring attention at the top. It supports agents like Claude Code, Codex, OpenCode, and pi, displaying cache countdown timers and git worktree workspaces. It runs locally on hardware you own, connecting securely via Tailscale, Cloudflare Tunnel, Caddy, or other reverse proxies.
