This was a drag and drop web page visual composer based on Firefox and the latest version I found is from over 13 years ago. If this project was continued could be so helpful for the indie web right now, specially for someone like me. I really struggled to get my page a descent layout by raw code but could just be so easy doing it directly on a visual program rather than writing code and see if it works in the live preview
I have never heard of this software before, but 13 years ago sounds like it didn’t survive the shift towards smartphones.
Basically, in the 2000s, most people looked at webpages through desktop computers or laptops, which had a certain screen size at minimum.
Many of these webpage builder programs therefore just had you placing boxes on a grid which was roughly that minimum size, allowing your page to be viewed on any screen with the same or larger size.Then smartphones happened and had a significantly smaller screen size. While it theoretically still works to build a webpage for the smallest screen size, the size difference is just far too big for it to still be ergonomic on desktop.
All of web development at that point switched from fixed pixel sizes to a rule-based approach that would allow for different layouts based on screen size.
And in particular for these webpage builder programs, this was a significant step up in complexity, because you needed to come up with some intuitive UI for users to enter these rules. I imagine, most of these programs never got updated to support the new paradigm and it was rather newly implemented programs that took their spot.
