AGPLOPEN SOURCE, SELF-HOSTED, WRITTEN IN RUST
Run every agent, on every machine, from one tower.
Firetower is a control plane for coding agents, on a server you own. It installs a worker on every machine you can SSH into, decides where each agent runs, gives it its own branch and worktree, and supervises all of them until one needs a human.

[ ANY DEVICE ]
Start On One. Finish On Another.
The agent runs on your server, not on the device you started it from, so every device picks up exactly where another left off. The same conversation, the same diff, the same branch — on a phone on a train.

[ HOW IT WORKS ]
Four-layer architecture
Top to bottom, this is the whole of it. Each layer is a separate thing that can stop without taking the others with it.
LAYER 04
Your Devices
Mac, Windows, iPhone, Android. Start a session on one, pick it up on another. Closing any of them stops nothing.

Firetower Server
The control plane, about 200 MB. It tracks every workspace, and if it goes down it catches up by replay.

Workers
One per machine you own, reached over SSH. A worker never opens a port and writes its own log before reporting.

Agents
Any coding agent, in tmux, on its own git worktree and branch. This is where the work happens.

[ TOKEN WATCH ]
Watch what every provider burns, by project, issue and teammate.
Claude Code, Codex, Kimi, Grok and the rest each burn tokens their own way, and none of them can see the others. Firetower watches all of them at once, and keeps the running total.

[ SETUP ]
Set Up In Three Steps
STEP 01
Install the server
One command on any Linux box. The control plane runs in about 200 MB, and there is no account to create.
$ curl -fsSL https://usefiretower.com/install.sh | shSTEP 02
Add a machine
Any machine you can SSH into: a VPS, a Mac mini, a box in your closet. Firetower starts a worker there. It never opens a port.
host hetzner-01 reach ssh state worker connected
STEP 03
Connect GitHub, pick an issue
Start from a GitHub issue or a Linear ticket. The agent gets its own branch and worktree, and keeps going when you leave.
ENG-142 Retry webhook deliveries branch eng-142 agent running
No. Firetower runs on your own machine, and there is no account to create.
Give It A Server. Close The Laptop.
Open source and self-hosted, with no account. Clients for macOS, Windows, iOS and Android.
