FileUp vs OneDrive

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.

OneDrive's API, served through Microsoft Graph, lets applications read, write, and share files and folders in a user's personal or organizational OneDrive. A live GET against the real gateway, graph.microsoft.com/v1.0/me/drive, returned a 401 without a token, reconfirming OAuth 2.0 auth over HTTPS, and a follow-up OPTIONS preflight returned Access-Control-Allow-Origin: *, resolving cors from unknown to yes. Personal Microsoft accounts get 5GB free, with paid Microsoft 365 subscriptions raising the storage cap substantially.
