sshoosh

sshoosh is a minimalist, self-hosted workspace chat designed for users who prioritize security, simplicity, and a terminal-centric workflow. Unlike traditional chat platforms, it operates directly inside an SSH session, providing a dense, text-based UI for channels, direct messages, threads, notifications, and more. Built as a single Rust binary with SQLite/libSQL support, sshoosh ensures quick startup times and efficient resource usage, making it ideal for sysadmins, developers, or teams seeking a private, lightweight communication tool without reliance on third-party cloud services. Its emphasis on SSH key authentication and optional app-level encryption enhances security, while its open-source nature invites customization and self-hosting. Overall, sshoosh stands out as a niche solution for terminal enthusiasts who want a seamless, integrated chat environment within their SSH workflow.
