I'm not sure what do you mean nothing real behind. Can you elaborate?
the script is not hosted under script.faqpopup.com thats why you cannot resolve the subdomain. The script url is visible after you purchased. Happy to share it though if you have doubts. Thanks
ut is a little bit smarter than f0. they provide ui components and server-framework bindings for file uploads.
I feel like f0 is a more minimalistic take on file management. More comparable to Vercel blobs than ut. I don't feel these two are comparable though. ut is a nice product if you are looking for those functionalities though.
The file0 package is relying on the presence of an evironment variable F0_SECRET_KEY that you can obtain from the dashboard. The example code is fully functional and secure, the authentication is happening in the background.
If you use env variables for the F0 secret you should do the same for S3? You’ve written the auth there out explicitly, but a new S3 client will pick them up from the environment as well.
