I'm very impressed! It's a really solid, Webflow-esque website builder with basically all the features you would need to build something legit, and it's OPEN SOURCE!

I would rate it 5/5, but in this case, open source means needing to know a bit of Github - but they do provide instructions on how to host it yourself.

There's technically no free plan, in the traditional sense, but being open source I did mark it as if it did.

Besides being open source, there's nothing overwhelming about it - but it is definitely a serious tool with a CMS system and forms built in.

You can run a legit website on this, with a backend and everything. And their paid plan is reasonably priced, with a generous amount of data!
