FileUp vs Google Drive

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.

Google Drive's API lets applications create, read, update, and share files and folders stored in a user's Drive, with fine-grained OAuth scopes for personal or Workspace accounts. A live GET against the real gateway, www.googleapis.com/drive/v3/files, returned a 403 without a token, reconfirming OAuth 2.0 auth over HTTPS, and a follow-up OPTIONS preflight echoed the request Origin in Access-Control-Allow-Origin, resolving cors from unknown to yes. The url was updated to Google's current Workspace documentation hub, which the old /drive/ path now permanently redirects to. Personal accounts get 15GB free, with paid Google One and Workspace plans raising the storage cap.
