You can use Excel as a CMS and while cool why use it for Prod? Especially because you are locking yourself into a company that may sunset or change pricing on the "feature" at anytime.
The public API is extremely important to the future of Notion. We maintain date-versioned backwards compatibility similarly to Stripe.
When it comes to your content, you can export your entire Notion workspace (or just the part of it that’s your CMS) as Markdown/CSV or semantic HTML, including all your uploaded assets and files. The HTML export is read to host as-is or post-process with BeautifulSoup, etc.
Investors will want an exit event, sooner than later. IPO (unlikely in next 2 years, macro issues) or flipping it to ... someone.
Just the normal cycle, nothing Notion-specific.
What is the "free" stuff you think would go away? The public API? But, we need to have a public API for many of our customers to be willing to pay us. It's an essential feature.
I’m happy this use case works, it’s a great showcase for how to get data in/out of Notion with their API. But I wouldn’t use it for anything that I couldn’t migrate to a different CMS quickly.
(And yes, I use Notion)
