Your Claude Code. Your Codex.One place to steer them.
byt Code runs your own coding agent on your Mac, in your repo, on a branch of its own. You see every step, say yes to what matters, and review every change before it leaves your Mac.
- In byt Code, a session is your own Claude Code or Codex on your Mac, on its own branch and worktree.
- Say what you want done. Every step it takes shows as it happens.
- In Ask every time, each edit and command waits for you: Allow or Deny.
- Each turn ends with a checkpoint: see what changed, or go back with Restore to here.
- Changes shows the turn’s diff, or the whole branch so far.
- Commit checks for secrets first. Push sends your branch with your own git sign-in, only when you press it.
Bring your own AI
byt Code drives the harness you already pay for, signed in on your own Mac. Llamabyt doesn’t sell tokens for it.

How a session works
Ask
Say what you want done. Your harness works in the session’s own worktree, and every step shows as it happens.
Approve
Edits and commands wait for your Allow, as much as you choose: every time, only the risky ones, or Auto.
Changes
Each turn ends with a checkpoint. See that turn’s diff, or the whole branch so far.
Restore
Didn’t like it? Put the worktree back as any checkpoint had it, in one click.
Commit & push
Commit with your own git name, after a check for secrets. Push when you press it, never before.
Working loops
Build, review, fix, until it’s right: one harness builds, another reviews it reading only, or your Mac runs your tests until they pass. Or let Dex-llama conduct: he plans, you approve, and he starts each turn. Every question still comes to you. On paid plans.
Safe by design
- Your Mac, your accountYour own harness runs on your Mac. We never see your sign-in.
- A branch of its ownEach session works in its own worktree, never your checkout.
- Commands stay insideYour Mac’s sandbox keeps them in the worktree, with no network.
- Pushing always asksPush, publish and deploy wait for you in every mode.
- Pages can’t take overAfter it reads the web, every command and edit asks.
- Secrets stay putScrubbed from every step, and checked before every commit.
- Diffs stay on your MacRead live when you open them, never kept by us.
- Only you drive itNobody else’s message or llama starts a turn on your Mac.

Questions
Do I need a Mac?
Yes, for now: byt Code runs your harness on your Mac with Apple silicon, through the Llamabyt Mac app 0.10.0 or later. You can follow and answer from any browser or phone.
Which harnesses?
Claude Code and Codex, signed in on your Mac with your own account. Claude Code asks before each step; Codex runs inside its sandbox, so its sessions run in Auto.
Does my code go to Llamabyt?
The steps your harness takes do, with secrets removed first, so you can follow them from anywhere. The diffs are read from your Mac when you open them and never kept.
Can my team use my sessions?
No: a session is yours alone, and only you start its turns. Each person brings their own Mac and their own AI.
