I built MyFoldy, a tiny (~1.6 MB) native macOS rule-based file organizer. Free & open source

Hey everyone!

My Downloads and Desktop folders always end up as a dumping ground for installers, screenshots, zips and PDFs. The organizers I tried were either subscription-based or heavy Electron apps, so I built my own: MyFoldy, a native SwiftUI app for macOS. I'm the developer, and it's completely free and open source (MIT).

What it does

• File name pattern rules: wildcard matching like *Invoice* → Invoices/ or IMG_* → Photos/, evaluated first
• 14 built-in presets: one-click rules for 100+ extensions (images, RAW, video, audio, documents, spreadsheets, archives, code, fonts, installers)
• Folder rules and exclusions: sort messy subfolders and uncheck any folder you want left alone
• Dry-run preview: shows every planned move (source → destination) before anything touches your disk
• Safe collision handling: never overwrites; duplicates become file (1).ext
• Auto-organize: runs in the background when a folder changes (FSEvents), with Open at Login support
• Dark, minimal UI with spring animations that respect Reduce Motion

Privacy and size

• ~1.6 MB download, pure Swift/SwiftUI
• 100% offline: no telemetry, no analytics, no network requests
• Uses security-scoped bookmarks, so it only accesses folders you add

Note: the build is self-signed, not notarized, so on first launch you'll need to right-click → Open. If macOS still blocks it, you can run xattr -cr /Applications/MyFoldy.app. The full source is on GitHub if you'd rather build it yourself.

I'd love feedback, bug reports, or ideas for rules you'd want (size/date-based rules, undo, menu bar mode?). What would make this useful for your workflow?
