Rex from Superlogical

Rex is a terminal multiplexer built by Superlogical. It keeps terminal blocks organized in long-lived sessions that can be accessed from a native macOS app or from other devices. It is in beta, with the macOS application and the Linux and FreeBSD servers available to testers.

What It Is

Rex is a terminal multiplexer that keeps multiple terminal blocks inside a durable session. You can close the application, reconnect from another device and pick up where you left off. Superlogical describes it as a drop-in replacement for the terminal you use today, with persistent sessions, responsive remote connections and program activity status. Sessions can be reached through the web and native macOS/iOS applications, and sharing a live session with others is built in. The team also says it is addressing common papercuts such as scrollback, selection and scrolling.

Customization and Automation

The documentation covers a configuration file, keyboard shortcuts, key sequences, key modes and custom actions. For automation it documents a CLI, agent skills, Lua scripts and events, shell scripting and a server API. Developers can build for Rex through a Program Status Protocol, and a community MCP integration is listed under beta.

Setup Path

The macOS client is self-contained and includes a local server. Invites go out to the mailing list, and testers log in with Discord to download it. Linux and FreeBSD are available as server-only installs, with install commands shown after Discord login. Superlogical says Windows servers and iOS, Linux and Windows clients exist at varying stages of readiness but are not yet part of testing.

Current Status

Rex is in public beta testing, with invites going out in waves from the mailing list. Superlogical states that Rex is and will always be free, requires no account, can be fully self-hosted, and that it does not see or share user data.

Product Direction

Superlogical frames the terminal multiplexer as the first step toward a multiplexer for all work, spanning interactive, automatic and production work. The stated plan is to build an excellent multiplexer, make everything in it composable, and make it safe to operate in production.
