Try NotionDog if you have no custom domain and no money. 😉

I believe it's the easiest way to build simple, powerful websites with nothing but Notion.

Hey there, Really appreciate this script, I am struggling with changing it with how Notion has changed their public site link options. I've used the FruitionSite Script could anyone help with this?

Notion errors out with "Mismatch between origin and baseUrl (dev)." during the worker preview. Any thoughts?

Generate again the worker script from the fruition site and paste into the Cloudflare worker script.
It worked for me.

"Hello, we've noticed an issue with your iOS app. Please delete this app and re-install it from the App Store."

There is an error when the site is opened through Safari on MacOS or iPhone. Has anyone managed to resolve it?
