This is why I'm building Pazly - https://pazly.dev
I'm sure when you've got your indie project idea, the first step you took was to look for (& buy) a domain name. As your concept evolves and you build idea maps, design concepts and the early phrasings of your pitch, you may not realise that you have all the ingredients to build a first landing page for your project.
The truth is that project websites are in constant evolution. I'm proposing that you start very early with a landing page that expresses your idea and tests the potential market. Many more variations will follow, as you discover you niche better, your business model will change ( and grow) constantly. It's all about iterations, just like with your code.
So why not try Pazly for your early landing pages?
Cool idea. Block editors seem to be everywhere these days.
Landing page could be clearer that it's not a hosting service, it's not clear until you read the FAQ and publishing guide.
Thanks @imsky! I'll make sure to make this more obvious in the next updates
