Box vs FileUp

Box is an enterprise content-management platform offering secure file storage, sharing, and collaboration, with a REST API and SDKs for building custom document workflows. A live GET against the real gateway, api.box.com/2.0/users/me, returned a 401 without a token, reconfirming OAuth 2.0 bearer auth over HTTPS, and a follow-up OPTIONS preflight returned Access-Control-Allow-Origin: *, resolving cors from unknown to yes. Personal accounts get 10GB free, while paid Business and Enterprise plans (plus metered Box Platform usage) unlock larger storage and API-driven workflows.

FileUp is a self-hosted, open-source temporary file-upload and sharing service built on .NET, offering a public REST API for anonymous uploads with configurable expiry times and view limits. A live OPTIONS preflight with an Origin header against the maintainer's own running instance, upload.sinasnp.com/api/public/upload, returned a 204 with no Access-Control-Allow-Origin header, resolving cors from unknown to no; the public upload endpoint requires no auth (only the separate admin panel uses Basic Auth), and HTTPS was reconfirmed. It's a free, open-source project with no paid tier.
