warp

warp provides a command‑line interface for sharing a terminal session over a network with a single command. A host can start a “warp” that spawns a new shell; other users connect to the same warp ID to view the terminal output in read‑only mode, and the host may grant write access to selected participants. The tool establishes TLS‑encrypted connections between the host, clients, and the supporting warpd server, and warp IDs are generated cryptographically to reduce the risk of phishing.

The primary audience is developers who need to collaborate on a command line without configuring SSH or a shared server, such as remote team members or new engineers being onboarded to a codebase. Because the session is multiplexed at the stdin/stdout level rather than using a terminal multiplexer, it works with any interactive program, though visual reconstruction may be slower for full‑screen applications.

Unlike tmux or screen over SSH, warp focuses on minimal setup and secure, temporary sharing. It supports commands to list connected users, authorize or revoke write permissions, and cleanly terminates when the host shell exits. The project is stable at version 0.0.3 and can be installed via Homebrew on macOS or built from source with Go.
