ZestSSH is a cross-platform SSH client (Android, iOS, Windows, Mac, Linux) built on one idea: own your tools, don't rent them. No subscription, ever. One-time $9.99, free tier needs no account and unlimited connections. Sync hosts and keys with zero-knowledge encryption on storage you control (WebDAV, S3, Drive, self-host), the server only holds blobs it can't read. Server monitoring, port forwarding, SFTP, import from PuTTY. Capstone project that turned real. Still just me.
