A native Mac terminal that keeps projects, sessions, and attention organized.
Run shells, dev servers, tests, and coding agents across several projects while Saggar tracks what is working, waiting, finished, and failed. Sessions that need a decision stay visible without pulling you away from the terminal you are using. Pair the Companion to check in and respond from your phone while you are away.
Mac only. Requires macOS 26 Tahoe or later on Apple silicon.
Running one agent is easy. Running five is supervision.
One agent is editing while another runs tests. A third has quietly stopped at a permission prompt, and a fourth finished ten minutes ago with changes to review. In a normal terminal, they all look like tabs. You find the blocked one when you happen to look.
Saggar keeps every state visible, folds away the quiet work, and builds one queue from everything that needs a decision.
The intro
The supervision loop
Start work across projects
Run agents, shells, dev servers, and tests across every codebase. Each session stays attached to its project, branch, and worktree.
Leave working agents alone
Sessions classify themselves as needs you, working, idle, finished, or failed. Quiet work folds away while the claims on you stay visible.
Clear the human queue
Waiting prompts and finished work form one ordered queue. Answer from the attention card, or press ⌘J to walk it from loudest to quietest.
Step away without losing the thread
Pair the Companion to see what your sessions are doing while you are out. Inspect a terminal, answer its prompt, interrupt a runaway, or type into it.
Tending from anywhere
- Sign in on both. The same Marginal Utility account on the Mac and on the phone. That match is what pairing allows, and the Mac checks it again on every request.
- Scan the QR code. Saggar → Settings → Remote control shows it, carrying an opaque Mac identifier and the live code, so nothing is transcribed. The account check runs first, then the Mac asks you to approve the device.
- Once, and then not again. Grants do not expire on their own — a phone in a pocket for six weeks is still paired. Signing the Mac out revokes every device at once, and any device can be revoked on its own.
Security that says no by default
Remote control ships on, because a feature you have to find and arm first is one nobody has armed by the time they need it. What says no is the account: nothing pairs that is not signed in as you.
A device pairs only while it is signed in as you — checked on every request.
The Mac dials out to the relay. It opens no port on your network.
One scan, and it holds. Signing the Mac out revokes every device at once.
Terminal requests and responses are encrypted end to end through the relay.
