Starting the build — why I'm making a native Mac SFTP client

Hey IH 👋

I'm Abdelhak, solo founder building Quarry a native macOS SFTP tool for developers.

The problem is simple: every time you upload a file to a remote server, existing tools give you a blind "Overwrite? Yes/No" with zero context. No diff. No rollback. No idea what you're about to break.

I've made that mistake enough times on production servers to finally do something about it.

What Quarry will do:

• Show a visual diff before every upload — see exactly what lines change

• Auto-snapshot the original file for one-click rollback

• Store credentials in macOS Keychain, not config files

• Native SwiftUI — no Electron, fast and lightweight

Building this as a side project. Will share progress here — the real numbers, the hard parts, and the decisions along the way
