Your computers. Your agents. One board.
Tethr runs Claude Code, Codex and Gemini CLI across the Macs and Linux machines you already own, and shows every agent on one board. No cloud workspaces: your agents stay on your hardware, connected over your own private network.
Working name. macOS first. Not available to the public yet.
Agents spread across machines are hard to keep track of.
One agent is waiting for approval on a Linux box, another finished on a second Mac, a third failed an hour ago. Tethr puts them all in one view, so nothing sits idle waiting for an answer.

What is in Tethr today.
One board for every agent
Claude Code, Codex and Gemini CLI sessions from every connected computer, sorted into working, waiting for you, done and failed.
Live terminals
Open any agent in a tab and work with it directly, whether it runs on this Mac, another Mac or a Linux machine.
Answer from the notification
When an agent needs a decision, Tethr notifies you on your Mac. Reply in the notification and the answer goes straight to that agent.
A manager agent
Describe a larger piece of work. The manager plans it, splits it into missions and dispatches them to agents.
Queues and schedules
Run headless tasks in the background on any machine, queue work for later and schedule recurring jobs.
Usage in one place
See agent usage across Claude Code and Codex sessions without opening each tool.
Networking built in
Computers connect over a private Tailscale network. A setup wizard adds a new machine with one command.
Dashboards from any device
Open web apps running on any connected computer in locked-down tabs, next to the agents building them.
Connect once, then work from one window.
- 1.
Add a computer
Run one command on the new machine. Tethr detects it on your private network.
- 2.
Start agents anywhere
Launch interactive or headless agents on any connected computer from the same window.
- 3.
Steer from one board
Watch progress, answer questions and review results without switching machines.
Where Tethr fits.
Good tools already run several agents on one Mac. Tethr is for people whose agents are spread across more than one machine and more than one vendor.

Based on each product's public pages in October 2026. “Not listed” means we could not confirm the feature, not that it is missing. Products change quickly; tell us if something here is out of date.

Running agents on more than one machine?
