The author of Ghostty has launched the public beta of his new terminal Rex, promising it will be permanently free and fully self-hosted.

Beating AI Express News: Superlogical, the new company founded by Mitchell Hashimoto – creator of terminal emulator Ghostty and co-founder of HashiCorp – has launched public beta testing for its new tool Rex. Positioned as a direct replacement for existing terminals, Rex adds key features including long-running sessions and remote connectivity: tasks continue running even after the terminal is closed, and users can resume operations when reopening the app or switching devices. Previously, Rex only completed a private beta test with around 50 users. The first public beta is limited to macOS, with invites issued in batches from a waitlist. Rex stores terminal sessions in the background, eliminating the need to keep the client window open. The macOS app saves local sessions natively and can also connect to Rex instances on other machines. It also offers CLI, Lua, and server APIs, supporting session creation, screen splitting, program launching, terminal content access, and direct terminal control via scripts. Superlogical has explicitly committed that Rex will remain permanently free, with no direct fees for clients or servers. Users do not need to create accounts and can fully self-host the tool; the company states it will not access or share user data. Linux and Windows servers are already operational, while iOS, Linux, and Windows clients are in development and not part of this beta test. Superlogical has not yet announced specific commercialization plans, which will be detailed ahead of the official full launch.
