FileFast vs Lufi

FileFast is a file-transfer service from Primo for sending large files by link or email and collecting incoming files through request links. Senders can see when transfers are opened and files downloaded. Recipients normally download in a browser without an account or app. Transfers may be public, limited to email-verified visitors, or restricted to an allowlist, and folder transfers preserve the selected folder structure. Verified recipients can preview supported work, comment on pages or timestamps, and approve or request changes. The service offers web, iPhone and iPad, Android, macOS, Chrome, and Firefox access, plus an API for uploads, tracked transfers, collections, verified submissions, and recipient activity. Free users get 5 GB per transfer and 10 GB storage at $0 per month; no credit card is required, though email verification precedes upload. Paid plans add larger limits, branding, review tools, team administration, and security controls.
