Terminalz vs TUIOS
Both stand on terminal multiplexers. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan iPhoneLinuxMac+2
Choose Terminalz if you want a free, self-hosted way to access terminal sessions from multiple machines in a browser, with tmux support and Herdr mirroring. Look elsewhere if you need more than 500 lines of phone scrollback or 2,000 lines on desktop.

Pick TUIOS if you want a free terminal workspace that tracks coding agents and can reconnect to sessions on local or remote machines. Look elsewhere if you need running programs and scrollback restored after a daemon restart or reboot, or cannot use a true-color terminal.

Terminalz: what it does well
- Connect any number of uniquely named machines to one web account.
- Mirrors Herdr sessions and layout, or exposes local tmux sessions.
- Supports bidirectional terminal streaming with focus-based writing and resizing.
- Agents use outbound authenticated WSS, without an inbound machine port.
- Terminal output and replay checkpoints remain bounded and memory-only.
What to know first
- The control plane must be self-hosted using Docker Compose.
- The native iPhone and iPad client requires building with Xcode.
- Phone scrollback is limited to 500 lines; desktop scrollback to 2,000.
- Public hostnames require Google OAuth configuration and an allowed email.
TUIOS: what it does well
- Free and MIT licensed.
- Tracks coding-agent states in panes and a shared Inbox.
- Supports multiple pane layouts, or turning tiling off.
- Sessions can stay available after detaching, including over SSH.
- Remote hosts can run sessions or individual panes.
What to know first
- Requires a terminal with true-color support.
- After a restart, running programs and scrollback do not return.
- Building from source requires Go 1.26.6 or newer.
- Security response times are not guaranteed.
