Tempest.app's answer

Tempest started as a mobile-first SSH client, born from the frustration of on-call fixes requiring a laptop, and grew into a full cross-platform remote-access workspace. The guiding idea has stayed the same: your servers shouldn't care which device you're holding, and your credentials shouldn't be readable by anyone but you — hence zero-knowledge sync from day one. The AI agent came later, from a simple observation: most terminal errors end with copy-pasting into a search engine, so the terminal itself should be able to read the error, propose the fix, and run it under your supervision.

Developers, SREs, and sysadmins who manage more than a couple of machines — mixed Linux/Windows estates, Kubernetes clusters, homelabs, and game servers. Teams use the shared encrypted vaults, session recordings, and SSH-CA access; enterprises with strict compliance run the entire backend self-hosted. The mobile apps make it a favorite for on-call engineers who want to fix a server without opening a laptop.

Against PuTTY: you get tabs, an SFTP editor, synced profiles, and point-and-click jump hosts instead of a single bare window plus WinSCP. Against Termius: Tempest goes beyond SSH — RDP, VNC, Kubernetes, Serial, RCON — and offers a one-time lifetime license plus a fully self-hosted backend, not subscription-only cloud. Against MobaXterm: the same multi-session workflow, but native on macOS, Linux, and mobile, not Windows-only. And the free plan is genuinely usable: SSH, Mosh, SFTP, FTP, S3, and WebDAV, forever, licensed for professional use.

Tempest.app's answer

Tempest treats "remote access" as one problem instead of five. A single app speaks SSH, Mosh, SFTP, FTP, S3, WebDAV, Telnet, RCON, Serial, RDP, VNC, and Kubernetes — and its grid workspace lets you split a remote desktop next to the terminal that's debugging it and the config file you're editing over SFTP. Three things competitors don't combine: a built-in AI agent that reads failing output and runs reviewed multi-step fixes (with parallel agents on desktop, each driving several servers); zero-knowledge end-to-end encrypted sync across Windows, macOS, Linux, Android, and iOS; and continuous sessions you can start at a desk and hand off to a phone.
