README

Run claude / codex / any CLI agent in daemon-owned sessions, and drive them from wherever you are: a minimal TUI at the desk, a tap-friendly web client on your phone. Sessions survive detach, replay scrollback on reattach, and can be watched from both clients at once. The daemon + wire protocol are designed to be reused unchanged by a future native iOS client.

Quickstart

1. Set up Tailscale first

agenton reaches your phone over Tailscale, so configure that before running agenton — the default agenton publishes over your tailnet and has nothing to bind to without it (why). One-time, on both devices:

1. Computer — install Tailscale (brew install tailscale, or the download), open the app, and log in.
2. Phone — install Tailscale from the App Store / Play Store, log in with the same account, and flip the VPN toggle on.

Both devices are now on one private network; day to day you just leave the toggle on. (Local-only, no phone? Skip this and use agenton up --lan.)

2. Install agenton

./install.sh

It asks where to put the binary, defaulting to /usr/local/bin:

Install agenton to [/usr/local/bin]:

Press enter to accept, or type any directory (~ works). It fetches a prebuilt release, or builds from source if Go is present and no release matches. To skip the prompt — for scripts, or curl … | bash, which never prompts — name the directory up front:

./install.sh -d ~/.local/bin        # or AGENTON_INSTALL_DIR=~/.local/bin

3. Run it

From anywhere (with the Tailscale app running from step 1):

agenton

That starts everything: the daemon (if not running), the web server (if not running), and drops you into the TUI. It publishes the phone bridge over your tailnet and prints a QR — no extra config, nothing to approve. Quitting the TUI leaves the daemon, web server, and all sessions running — agenton again to come back. Logs land in ~/.local/state/agenton/.

Headless (a server that only needs daemon + web): agenton up -no-tui.

Prefer to build by hand? go build -o agenton ./cmd/agenton still works; run it as ./agenton.

Phone access (Tailscale)

Why Tailscale

agenton speaks plain HTTP and exposes nothing to the internet. Instead it rides your tailnet — a private Tailscale mesh VPN (WireGuard) that puts your computer and phone on the same encrypted network no matter where either one physically is. On the couch, on cellular, or across the country, the phone reaches your daemon exactly as if both were on your home Wi-Fi. The tailnet is the security boundary: only devices logged into your account can reach the port, and the wire is encrypted for you.

agenton uses the system Tailscale app already on the computer — it registers no tailnet node of its own, so there's nothing to approve, no login link, and it works on the free plan. Install it once on both devices (Quickstart step 1).

Connect (every day)

agenton up -no-tui      # binds the computer's tailnet IP and prints a connect QR

On the phone, open the agenton iOS app, tap ⚙︎ → Scan QR, and scan the block it printed. Reprint any time with agenton qr.

No app? The server also hosts a web client. Open the printed http://… URL in any browser on your tailnet, or run agenton qr --web for a QR of that URL you can scan with the phone's plain Camera (it opens straight in the browser — no scheme, no app). To make it feel like an app, use the browser's Share → Add to Home Screen for a full-screen launcher icon.

Modes:

• agenton up (default) — over the tailnet via the system Tailscale app.
• agenton up --lan — localhost only, no tailnet publish.

Using the TUI

The TUI is a minimal terminal wrapper: at the desk you type to the agent directly, and the TUI just adds session switching on top.

Entry screen (session list): enter attach · n new session · d delete · r refresh · q quit. n opens a plain shell in the directory you launched the TUI from — you run claude/codex (or anything) inside it, cd-ing wherever you like first. The list auto-refreshes, so sessions you start or kill from the phone/web client show up on their own, and each row's path tracks where its agent is actually running (the shell's live working directory), not where the session was first opened.

Session view: a full-screen raw terminal with no chrome — every key goes straight to the PTY, exactly as if you'd launched the shell here. The one reserved key is ctrl+t, which returns to the session list to switch sessions (the session keeps running, so it doubles as detach). The on-screen button pad and custom-key rebinding live on the phone/web clients, where there's no physical keyboard to type with.

Using the web client

Mobile-first mirror of the TUI: session list (tap to attach, ✕ to kill, new sessions via a command + cwd form), live terminal, a 4×3 button pad (accept / reject / mode / stop · ▲ ▼ ◀ ▶ · esc / rewind / 2 custom), and a text bar. The Pad/Term button switches between Terminal (the phone owns the PTY size, terminal renders correctly) and Controller (the desk owns it; the phone becomes a full-screen button pad instead of a shrunk frame) — the phone parks itself into Controller automatically when you start typing at the desk.

• New-session suggestions: chips above the form — sessions currently running under the daemon, agent processes discovered elsewhere on the host (claude/codex/cortext/ollama run, clonable but not attachable), your recent commands (per-device), then starters. Tap to fill, edit, go.
• Rebind custom buttons: long-press Custom 1/2 → tap-to-compose picker (chips for keys/combos, text field for literal strings) — no combo typing on a phone.

Shared sessions

The TUI and web client are two views of the same daemon: create a session in either, attach from both at once — output streams live to every attached client. Exactly one client owns the PTY size at a time (the "active" device): it renders the live terminal, and everyone else parks into a purpose-built role instead of showing a mis-sized frame — the desk TUI freezes its last frame behind a "press any key to take over" hint, and the phone clients (web and iOS) flip to Controller mode. Buttons and text still work while parked; they drive the agent without stealing the size.

Configure (optional)

Presets pin an agent + cwd + custom buttons under a name:

mkdir -p ~/.config/agenton
cat > ~/.config/agenton/config.toml <<'EOF'
[preset.api-refactor]
agent   = "claude"
cwd     = "~/repos/api"
command = "claude"

# Only the two custom buttons are configurable; accept/reject/mode/
# interrupt/rewind are fixed per agent (claude/codex/shell), detected
# from the session's command line. Each custom button holds one value:
# a key name / combo (Ctrl+O, Shift+Tab, Esc, ...) or a literal string.
[preset.api-refactor.buttons]
custom_1    = "Ctrl+O"
custom_2    = "/compact"
EOF

Commands

agenton                 # start everything (daemon + web if needed) and open the TUI
agenton up -no-tui      # start daemon + web only (headless/server)
agenton tui             # just the TUI (daemon must be running)
agenton web             # just the web server (default 127.0.0.1:9787)
agenton daemon          # just the daemon (socket at ~/.agenton/agenton.sock)
agenton qr              # publish over Tailscale + print the iOS connect QR

Test

go test ./...             # unit + e2e (local, simulated-remote, WS bridge)

Hacking on it? ./dev.sh rebuilds, restarts the daemon + web, and installs a fresh iOS build on a simulator pointed at it. The steps are independent — ./dev.sh ios leaves your running sessions alone, ./dev.sh -h lists the rest. Note the web client is embedded in the binary, so editing internal/web/static/ needs a rebuild + restart, not just a browser reload.

Architecture

TUI (Bubble Tea) ────Unix socket────┐
phone browser ⇄ WS ⇄ agenton web ───┴──> daemon (owns PTYs) ──> claude / codex / …

Wire frame: [1 type][4 session_id][4 len][payload]; 0x01=control JSON, 0x02=raw PTY bytes. One WS binary message = one frame. The daemon listens on a Unix socket only and never opens a public port; remote access rides your tailnet (the web server binds the machine's tailnet IP, never 0.0.0.0). Sessions persist across detach (daemon-owned PTYs + scrollback ring buffer); reattach replays scrollback then streams live output.
