I'm looking for some kind of File Drop / File Upload service.

I'd like to be able to create a folder, and create a share / upload link for that folder that I can give to a customer to use to upload their documents.

I've been using nextcloud but I don't use nextcloud for any other purpose and it's a behemoth so I'd like to transition to something else.

Some of these requirements are essential (!):

• no login for customers uploading (!)
• optional password protection for uploads
• can't see / download files already present in the shared folder
