Google Drive and Microsoft 365 as real Finder volumes. You decide per folder: hoarded — kept fully offline and synced both ways — or only on demand. No macFUSE, no system driver, no gigabyte sitting in the background.
Connect an account, pick your folders. From then on you work in column and list view as always — all Hamster ever is, is a mark on the folder corner and an icon in the menu bar.
Several Google Drive and Microsoft 365 accounts at once, each with its own sign-in, each its own entry in the Finder sidebar. Personal and work no longer have to take turns.
Right-click, “Hoard folder” — the folder then sits fully on disk and is synced both ways. Everything else stays online and arrives when you open it. Subfolders inherit the decision.
Three statements, three marks — and the same marks everywhere: on the folder, in the menu bar, in the window. No percentage bar to interpret.
Accounts on the left, the folder tree with each folder’s mode in the middle, everything about the selection on the right. If all you want is to hoard, you will not come back here after setup.
Because the rest either wants a lot of machine or is not Finder. Every number below was measured on a MacBook with an M4, not estimated — same data set, same rclone build.
Test setup: Mac16,12 · Apple M4 · 32 GB · macOS 26.5.2, rclone 1.74.4 on both paths, data set of 4,000 files × 512 KB. A note on fairness: Mountain Duck was running with the machine’s real configuration (connected accounts, active volumes) and was deliberately not restarted or reconfigured — the number shows the everyday steady state, not the theoretical minimum. Even with that caveat, the gap in memory stays at a factor of 10–15.
Not a marketing word. Hamster is at version 0.3 — it works, but it has not been in other people’s hands long enough.
Hamster is meant to cost money eventually — whether once or as a subscription is not settled. Anyone in the beta tests for free and keeps their build; we will name a price only once we can stand behind it. No credit card, no trial period, no automatic slide into some subscription.
