Show HN: ColliePWA, a self-hosted mobile terminal for coding agents, with alerts

Sharing the PWA[1] I built over the last couple of weeks to access my terminal sessions/agents when not in front of my computer. This started off as a weekend experiment right when herdr[2] (terminal multiplexer) released the functionality to write custom plugins and it's been quite helpful to me ever since. The general idea is that this runs a web app on the host machine which is then exposed through a front door implementation like tailscale/netbird/cloudflare tunnels etc.

A lot of devs/teams are building sth very similar to this right now so there are many options out there already but I wanted: A PWA (no app store dep), better keyboard support than termux, the ability to manage multiple machines and easy integration with my existing tailnet via headscale.

Some of the other features - Push notifications - Support for tmux and zellij (experimental) - Voice transcriptions (Codex sub or API) - Custom commands for cc/codex/pi etc (add your own) - Visual cues for when token cache goes stale

You can check out a live demo with dummy data on the website[1] or look at the implementation on Github[3] (PRs welcome).

Looking forward to receiving some feedback or learning more about how people access/work with their agents on the go. Also if you encounter any bugs please report them on Github, if a feature is missing you'd really want to see, open a discussion.
