    WebStudio is very impressive. As a long time power user of WordPress, then SSG like Hugo; with WebStudio I'll definitely never look back on these archaic tools. Intuitive, Fast and a must, the team are super friendly and hyper reactive on Discord ;)

    Well, Marx still in development and is not available yet. From what I understand, it will be the result of merging of all the Mars Verse: Unicorn Platform, Fleexy, Marketsy, ... You could give a shot for free to Unicorn Platform to get the vibe. ;)
