Your S3 bucket in Finder, without the local copy.

Mount Amazon S3, Cloudflare R2, Backblaze B2, MinIO — any S3‑compatible bucket — as a location in the Finder sidebar. Files stay in the cloud until you open them, and leave your disk the moment an upload is confirmed. A 200 GB bucket costs you nothing locally.

macOS 14 or later · Current beta 0.3.0‑beta.1, 28 August 2026

Your credentials stay on your Mac and talk only to the storage endpoint you configure. The one other connection it makes is a daily update check against this site.

Nothing lands on your disk unless you ask.

Browse the whole bucket in Finder; only the files you open are downloaded. After an upload is confirmed remotely the local copy is released, and a cache cap you set keeps the rest in check — with a “Free Up Space Now” button when you want it back immediately.

A real Finder location.

Built on Apple's File Provider framework, the same one iCloud Drive uses, so every app sees your bucket as an ordinary folder. Drag, rename, move folders, save from any app; large files upload in parts and interrupted transfers resume.

You can see what it’s doing.

The menu bar icon shows uploads and downloads as they happen, with a warning badge if something needs you. One click opens live transfers, cache usage per account, and any connection errors.
