FileUp vs Pantry

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.

Pantry is a free JSON storage service for small projects and prototypes: each Pantry is a namespaced bucket identified by an ID in the URL path, holding arbitrary JSON "baskets" read and written over a plain REST API. A live GET and OPTIONS preflight with an Origin header against the real host, getpantry.cloud/apiv1/pantry/, both returned Access-Control-Allow-Origin: *, reconfirming cors as yes; no API key is required (the Pantry ID itself is the access credential), and HTTPS was reconfirmed. The service is entirely free with no paid tier.
