Your AI lives on your machines. BrainBoxx keeps it within reach, wherever you are.
Leave the desk and your coding agent comes with you — open the app and you're back exactly where you left off. Built for developers who live in the CLI.
The AI you rely on shouldn't depend on the machine you're sitting at.
You don't need a command centre.
You just need to leave the desk.
BrainBoxx isn't mission control for a fleet of agents. It's for one person, mid-flow, who just wants to keep going after they step away from the desk.
Your AI never loses its place.
An agent runs for hours. You don't sit and watch it. You move — to a meeting, to bed, to the other side of the world. The work should still be right there when you get back. With everything else, it isn't.
- Dig out the laptop
- Connect the VPN
- SSH into the right box
- Find the session (tmux? which pane?)
- Reconnect the dropped shell
- Resize the mangled terminal
- Finally — continue
- Open app.
- Continue.
Reconnect, resume, resize — all of it, gone. It just opens onto the conversation, mid-thought.
Fair warning.
Three days in, you'll hate going back.
Once your AI can follow you, a bare session feels broken — walk away and the conversation is marooned at the desk. That's not a line we wrote; it's what happened to us.
Put the laptop down.
Keep the momentum.
Same Brain. Same conversation. Same context. No reconnecting, no finding sessions, no restoring anything — and if it needs you while you're away, your phone quietly says so.
Machine → Folder → Brain
One clean model. A machine is a Mac, server or droplet. A Folder on it is a place you keep work. Each project inside is a Brain — a live or dormant AI session, not a dead folder.
Pair a machine
Get the app — it mints your one code — then run a single line on any Mac, server or droplet. It sets itself up and joins your fleet. No account, no dashboard.
Your agents show up
Every Claude, Gemini, Codex or Grok session becomes a Brain on your phone — with a live status you can read at a glance: working, needs you, or waiting to continue.
Tap in from anywhere
A real terminal in your pocket, with comfortable typing. Type, take control from the desk, throw it a screenshot — or just watch it work.

Never blocked by
your hardware again.
Mac asleep? Server offline? Away from your desk entirely? Pick a GitHub repo and BrainBoxx builds a fresh machine from it — set up and already signed in to your AI. Jump in, fix what's broken, throw it away when you're done. A whole dev machine, made in a tap and gone when you don't need it. Right from your phone.
+
Pick a repo and a whole machine builds itself onto your Home Screen — ready to drive in about a minute.
You sign in once, ever — every machine you spin up after that arrives already you. And because it's your own private box, you drive at full speed: no "allow?" on every edit. A workstation on demand, from your pocket.
Claude, Gemini, Codex, Grok — every agent you run, in one place.
Made for your phone.
Not squeezed onto it.
A real terminal that feels right one-handed. Something breaks on your phone? Screenshot it, drop it into the Brain, ask "what's wrong here?" — your coding agent, debugging from a park bench.
- › Sign a headless server in through your phone — it's the browser the box doesn't have.
- › Take control from the desk with a tap; hand it back just as fast.
- › Autocorrect-friendly typing — you're writing to an AI, not fighting a shell.
Stop checking.
Your Brains will tell you.
The best notification is the one that lets you look away. A Brain finishes, needs approval, or is waiting on you — your phone says which, and a tap drops you in. You stop watching the terminal. The work comes to you.
1 needs you
The Fleet Status widget keeps your whole fleet a glance away — and when one Brain needs you, the Dynamic Island wraps the camera, a tap from dropping in. No unlocking.
Locked and pocketed — the one Brain waiting on you, as a tappable Live Activity card. A push gets you there, and nothing idle ever shows up here.
No account. No cloud.
No login.
The work runs on your machines — BrainBoxx just connects you to it. Nothing to sign up for, nothing in a database. One code pairs your phone to your machines, and it's the only credential there is.
Download and go. No email, no onboarding funnel, no "verify your account."
Your agents run on your machines. The relay only brokers the connection — blind, byte for byte.
No account means no database of you to breach or sell. There's simply nothing there.
Free is the app. Pro reaches out to you.
Everything's there the moment you open it — free, forever, in one Folder. Pro means you can stop opening it: it pings you when a Brain needs you, runs every Folder on every machine, spins up a fresh machine from any repo, and lives on your Home Screen.
- One Folder — all the Brains inside it
- Every AI — Claude, Gemini, Codex, Grok
- The full terminal, continue where you left off
- Files & photo upload — throw a screenshot at your agent
- See what every Brain's doing at a glance
- Everything in Free
- Spin up a cloud machine from any repo — a dev box in a tap
- Push the moment a Brain needs you — or finishes
- Every Folder, on every machine — no limit
- Home Screen widgets, Dynamic Island & needs-you alerts
- Everything in Pro
- One payment, yours for good
- Every future update included
- Founding-member badge
- For people who hate subs — us too
Built by someone who uses it.
I built BrainBoxx because I needed it.
I use it every single day — every feature, fix and release built on the exact workflows you will. My Brains keep running when I leave the desk; I pick them up on my phone and carry on mid-thought.
If something feels awkward I feel it immediately, because I rely on it. I genuinely wouldn't want to work without it now. It isn't a project I work on — it's the tool I work with.
Pick up exactly where you left off.
On any device.
Get the app — it mints your fleet code — then paste one line on each machine. You'll be continuing a Brain from your phone in about two minutes.
No account. No cloud lock-in. One fleet code links your devices, end to end.
