ZestSSH launches a five-platform SSH client built mostly with Claude Code
Cybersecurity student and infosec professional Ryan Lavery has released ZestSSH, a free SSH client for Android, iPhone, Windows, Mac and Linux. The developer says it offers end-to-end-encrypted synchronization for hosts, keys and snippets, SFTP, port forwarding, split panes, jump-host chains, team vaults and a recording mode that hides hostnames and IP addresses. It requires no account or subscription, with one-time upgrades available. According to the developer, Claude Code implemented features from detailed specifications and checklists, while Lavery tested the results, reviewed its proposed encryption design and used it to audit the project. The audit reportedly identified a mismatch between the security documentation and the backend before any production synchronization occurred. The product’s security, encryption and cross-platform capabilities have not been independently verified.
The developer’s account illustrates a spec-driven AI-assisted workflow in which Claude Code built features, the developer tested and reviewed them, and an AI-assisted audit found a gap between documentation and implementation. It also highlights the developer’s finding that smaller specifications worked better than large UI changes.
| So basically I’m a cybersecurity student and I work in infosec full time. My capstone was supposed to be a small SSH app just for funsies which then turned into ZestSSH, a full SSH client for phone and PC with end-to-end encrypted sync, built mostly with Claude Code. Why I built it: JuiceSSH died, and Termius wanted a yearly subscription just to sync my hosts between my phone and my PC. What it does now: How Claude Code helped: What didn’t work: Drag-to-detach windows on desktop. Claude tried a bunch of approaches, Flutter just isn’t there yet. Honestly thought about just making my own fork of it at this point lmfao Huge UI changes in one go drift. Smaller specs work way better. It’ll agree with a bad idea if you let it, so now I ask it to argue against me first. Try it: free to use with no account needed. Google Play, App Store, Microsoft Store, or zestssh.com for Mac and Linux. Upgrades are one time, no subscription. https://zestssh.com/ Tell me what you think, or roast it, either works. I plan on open sourcing it once I’m happy with everything! submitted by /u/ISpeakTheLie [link] [comments] |
