Claude, Codex & friends keep coding on your PC at home — and you watch the whole classroom live, from any browser, anywhere.

Dear parent or guardian,
You kick off a long agent run, and then life happens — you leave the desk, you leave the house. Meanwhile a very enthusiastic child is alone at your computer: maybe finishing the refactor, maybe stuck on a permission prompt for forty minutes, maybe writing tests nobody asked for. You simply cannot tell from the bus.
So I built them a classroom. Every agent on your PC becomes a student you can watch live — a real terminal you can type into from your phone. When a dev server appears it goes on the Show & Tell shelf. When somebody stalls, errors out, or raises a hand to ask permission, you get a note. And if you'd like, I will personally read their scrollback and send home a report card.
One thing I insist on: the relay between us stores nothing — no database, no logs, just passed notes. And the children's credentials never leave your house. They use the CLIs you already installed and logged in yourself.

Every feature, graded the only fair way: by the teacher.
Every agent session (Claude Code, Codex, any CLI) streams as a real terminal you can watch and type into from any browser. Phone included.
Your terminal, your browser, and your phone are three windows into one session living on your PC. Start at the desk, continue on the couch — it never forks, and closing a window never kills it.
Dev servers your agents start (localhost:3000 and friends) are spotted automatically and can be opened live through the tunnel — see the actual app, not a description of it.
Stalled for ten minutes? Hit an error? Waiting on a permission prompt? The student's hand goes up and your phone gets a push notification. No more discovering the 40-minute nap at midnight.
Miss Clanker reads each student's scrollback and writes an actual report card — grade, highlights, concerns, next step. Bring your own OpenRouter key, or she just borrows the claude CLI you already have.
"B+ for grading herself. Shows initiative."
Which machines are connected and which students are awake, at a glance — with avatars, because every class needs a photo wall.
Three parts. The important arrow points the wrong way on purpose.
Anyone holding your access token can drive your machine — that is literally the product. So the rules are strict.
Your PC opens no public ports. The daemon dials out over WSS and that's the only door — and it only opens from the inside.
Cookies are derived from your access token. Rotate the token on the relay and every logged-in browser everywhere is out. Instantly.
With --lock-commands the daemon only ever spawns its built-in presets — even a fully hijacked relay can't launch arbitrary commands.
With --view-only the daemon drops all keystrokes arriving from the relay. The web can watch; only your local terminal may type.
# install the daemon > npm install -g agentkindergarten # point it at your relay, then leave it running > agk init --relay wss://your.relay --token <pairing> > agk start
# type this instead of `claude` > agk claude # born in the classroom AND in your terminal. # phone, browser, terminal: one session, three windows. # Ctrl+] leaves quietly — the kid keeps playing.
The relay is one small Docker container on any VPS — Compose file and Let's Encrypt included. Then open it in a browser, log in, and take attendance.
