ZestSSH
Product· Version 3.2.7
One SSH client on five platforms, with sync we cannot read.
The problem
People who look after servers use a different app on every device, and syncing passwords and keys between them usually means trusting someone else's cloud.
What we built
A full SSH client for Android, iOS, Windows, macOS, and Linux: terminal, file transfer, port forwarding, and a live server monitor. Credentials sync end-to-end encrypted, to our cloud or to storage the user runs, so we never see them.
How it turned out
- On Google Play and the App Store, with installers for Windows, macOS, and Linux
- A published security whitepaper that explains the full sync cryptography
- A free tier and a one-time purchase, with no subscription
What it means for your business: The same habits go into client work: encryption where it matters, real testing, and software that actually ships.
