TermPair is an open-source tool that lets you securely share a live terminal session directly in a web browser. All terminal input and output are end-to-end encrypted, so the relay server never has access to your data.

It supports Linux, macOS, and Windows, offers read-only or interactive sessions, and is distributed as a single binary with no Docker, Node[.]js, or Python dependencies required.
