Conmux vs Ferrix

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.

Conmux

Free plan Windows

Conmux combines supervised Windows terminal panes with a reconnectable daemon and local control interface. Its early development status and the loss of all panes when the daemon stops are important operational limits.

Ferrix

Free plan LinuxMac

Choose Ferrix if you want a free terminal multiplexer with remote transport options, snapshots, recording, and multi-client sessions. Look elsewhere if you need a packaged Homebrew or crates.io install now, or require non-experimental crash recovery or plugins. For mission-critical use, the project recommends independent security validation.

  • Offers session snapshots and compressed recording with replay.
  • TOML configuration supports hot reload and custom keybindings.

What to know first

  • Homebrew and crates.io installation are marked as coming soon.
  • Crash recovery and the plugin feature are experimental.
