Termalin
Termalin is an SSH client for people and AI agents, combining terminal sessions, file tools, database access, and agent connections. Its terminal offers xterm-256color sessions, browser-style tabs, a hosts sidebar, snippets, and session restoration with scrollback. File tools include SFTP, FTP, and S3 browsers, an editor, and a dual-pane transfer manager. The database client supports 13 engines, including PostgreSQL, MySQL/MariaDB, SQLite, MongoDB, Redis, and SQL Server. Its MCP server lets agents open sessions, run commands, work with files over SFTP, and join live sessions while users watch. A web cabinet provides terminal, file-browser, and recording-replay access without installing the app. Termalin lists API, iOS, Linux, macOS, web, and Windows platforms. The free plan includes SSH and SFTP; Pro costs $8/user/mo (annual), and a 14-day trial is listed. The Windows .exe is not code-signed and may show an unknown-publisher warning; the Microsoft Store build is signed.
