The original consumer cloud-storage + file-sync name — Dropbox Basic gives 2 GB of free storage with cross-device syncing, file sharing, and a polished app on every platform. The old 3-device sync limit was lifted in 2025, so Basic now syncs unlimited devices. Paid Plus from ~$9.99/mo for 2 TB; the deep third-party-app integration ecosystem is Dropbox’s real moat.
