**Tempest** is a modern SSH client for **macOS, Windows, Linux, and the web** — with native support for SFTP, jump hosts, port forwarding, OpenSSH certificates, FIDO2 / YubiKey, post-quantum algorithms, and a built-in AI assistant. Beyond SSH, Tempest also handles Kubernetes, Telnet, Serial, RCON, S3, WebDAV, and FTP — all with the same tabbed terminal experience.
