1SessionTool
All switching guides

Stay on tmux if you like prefix. Leave if you don't.

tmux is the category. Acquisition is not 'we are better tmux'. It is first-use taste, glass, and an API.

Stay if this is you. People who already live in prefix, who want a cheatsheet they already know, and who do not want a GUI or a phone client.

Prefix, then a viewport

One client, one view. Independent scroll and select on a second glass is not the product.

Phone is not a client

tmux attach from a phone is a terminal in a terminal. 1SessionTool treats the phone as glass onto a host that stays on.

Agents speak argv, not a prefix language

1session spawn --session work --server vps1 -- claude. The agent is the command. There is no wrapper named after a vendor.

If you do switch

  • Native scroll, select and copy. Each client owns its viewport.
  • Attach from Mac, PC, browser or phone without killing the PTY.
  • Named servers with honest lid physics. Local dies. A remote host stays up.
  • CLI and HTTP API so 1DevTool and agents can drive a pane.
