Why TERYON

Separate the shell from the connection.

A small per-user service on your Mac mini or Linux host owns the terminals. Your laptop connects over the OpenSSH you already trust. No new ports, no new accounts.

Persistent

Real PTYs on the host

Disconnect, sleep, or quit the client. Reconnect to the same live shells.

Plain SSH

Your keys, your config

Ports, jump hosts, agents and aliases stay in your existing OpenSSH setup.

Themes that repaint ANSI

Colors 0–15 follow the theme, so ls, git and editors look right.

Persistent by design

Close the laptop. Your shells stay.

The daemon owns the terminals, not your connection. Try it.

🖥️

Mac miniteryon daemon

4 shells running. A build is at 63%.

Native desktop

One slim bar. Everything else is terminal.

A GPU window over the same persistent shells. Drag splits, navigate by keyboard, search scrollback, and open the command palette for the rest.

Built for coding agents

See which agent needs you.

TERYON watches each pane's foreground command and shows a status chip for Claude Code, Codex, Gemini, aider, Cursor and OpenCode.

Own worktree

Start an agent on its own Git branch, so its edits stay out of your checkout.

Sandboxed on request

teryon sandbox -- claude limits writes to the repository and hides ~/.ssh.

MCP server

teryon mcp gives MCP clients durable panes, local or over SSH. Reads are always on.

# give Claude Code a terminal that survives
$ claude mcp add teryon -- teryon mcp --allow-write

# run an agent where it can only write to this repository
$ teryon sandbox -- claude

A guard against mistakes and leaked credentials, not a boundary against a hostile program.

A Finder in your terminal

Press ⌘B. Browse anything.

A sidebar follows cd, previews files with Quick Look (code is syntax-colored, with find), and works the same on a remote host over your SSH connection. Nothing is deleted: items go to the Trash.

A link that explains itself

Laptops sleep. TERYON tells you why.

When the link is down you get the real reason and the next step, not a spinner.

● SSH refused your key · mini.local
ACTION NEEDED
Check ssh -o BatchMode=yes mini true in a
terminal and that ssh-add -l lists your key.
ssh said: user@mini: Permission denied (publickey).
Your shells keep running on the host and
reconnect as soon as this works.

Screen diffs, not screenshots

Over SSH the app asks for a scroll plus the rows that changed, checksummed, with an automatic full resync. In one scrolling-output test the screen bytes were about 17× smaller and the whole reply stream about 7×.

Take control

Another device holding the seat on a half-dead link? One command takes it over; the old controller keeps watching, read-only.

Wi-Fi / DNS · host asleep · key refused · changed host key · teryon missing

The 17× and 7× come from one test, not a benchmark against other tools; see the test report.

Themes

23 themes. One WezTerm export.

Mac27, Apple, Tokyo Night, Catppuccin, Dracula, Nord and more. teryon themes --export wezterm NAME gives your terminal the same palette.

An engineering preview, honestly. TERYON has real tests, including a real daemon and real shells, but not every feature has been exercised on every machine, and it makes no claim to beat tmux, Zellij, WezTerm or Mosh. Read the known limits and the test report before you rely on it.
