Why Folder
One folder on your Mac, your iPhone and the web. Kept with us, or in your own Cloudflare.
It's Just a Folder
Folder sits in Finder's sidebar and in the Files app, and opens at folder.dev in any browser. Files download when you open them. Drop one on the menu bar icon and its link is on your clipboard.
With Us, or in Your Cloudflare
Start on ours and move a folder to yours whenever you want.
Nothing Is Lost
Every overwrite and every delete is kept, on the Mac, the iPhone and the web. Each version says who made it, and putting one back keeps the one it replaces. R2 has no history of its own; Folder adds it.
Agents Work on Something You Can Undo
Before each Claude Code session, Folder copies the project on your Mac, then lists what the session changed for you to keep or put back. ChatGPT and Claude reach only the folders you pick, and ask before they share anything.
Projects That Don't Choke Dropbox
Add a project that lives in Dropbox to Folder. node_modules and the other build folders stay out of Dropbox and Time Machine, and new ones are left out as they appear.
