Documentation

Firetower is a control plane for coding agents. Give it a machine you can SSH into and a repository, describe some work, and it cuts a branch, opens a worktree, starts tmux and keeps the agent running — then tells you the moment it stops being useful without you.

Two ways to run it:

Host it yourself — the app on a machine you control, and a worker on every machine that should run agents.
Firetower Cloud — the app runs for you. Coming soon.

Start

Getting started→Two ways to run Firetower — host it yourself today, or the cloud when it arrives. What each one asks of you.How it works→The two things you run — the app, once, and a worker on every machine that should run agents — and the shapes that work.

Install

Overview→Three setups — on your computer, on a server over SSH, or on a server with a custom domain — with a drawing of each, and what the control plane and the worker each do.Install on your computer→Install the app on the machine in front of you: every question firetower install asks, what it writes, and what it leaves on loopback.Install on your server, through SSH→The same loopback install, on a machine that stays awake, reached from your laptop with firetower tunnel. Which port to pick, and what the tunnel does and does not carry.Install on your server, with a custom domain→A real name and a real certificate over Tailscale, with nothing reachable from the internet: how DNS-01 does that, the two DNS records, the certificate wait, and every failure it can hit.Add a machine→Run sessions on a server you already own: install the worker with the CLI, then add the host over SSH.DNS providers→Every DNS provider Firetower can obtain a certificate through: which credential each one needs, which take a single token, and which need a block written into the Caddyfile.

Upgrade

Upgrade the app→firetower upgrade backs up the database, pulls the new release, and names every machine left running an older worker.Upgrade the worker→Drain the host, recreate the container, resume it — and what a worker that has drifted behind the app stops being able to do.

Operations

Daily operations→Backups, the commands you reach for, running behind a proxy you already have, and who is allowed to use your Firetower.

Using Firetower

Connect repositories→Paste a URL, or authorize GitHub with an OAuth app so you can pick from a list. Both, and why it is an OAuth app.Secrets→Every credential Firetower holds is sealed with envelope encryption. Where the root key lives, and why it is backed up apart from the database.

Getting started is the short version of the choice. If you already know you want to host it yourself, how self-hosting works explains the two things you run, and Install is the two-minute version.
