TLDR: Lookup Sveltia CMS

> The truth is, there has been no successful CMS for static-site generators because the only people that give a fuck about creating static sites would much prefer to use a (free and local) IDE and a terminal.

I completely disagree with this. The main problem is that these people don't want to pay for such a solution.

There's a thriving ecosystem of headless CMS for commercial websites: multi-user, support editing landing pages, etc.

Things like Decap were too basic (running it for any complex blog is a pain) and didn't solve much for developers building a Github Pages blog (while also being useless to startups).

I run three static blog websites, two personal and one for our agency. I want a CMS on all of them. I want to be able to edit from the iPad, easily upload images, etc. But my hosting itself is basically free, so hard to justify paying for a CMS.

I'm using Sveltia for all three now, it's still in early access but in my experience is much better than NetlifyCMS/Decap or PagesCMS.
