The story behind PlantUML Ultimate — Online PlantUML Editor
Why I built it
Always liked the open PlantUML format, but never really found a tool that could do all I wished for.
How it's built
To know what to add and whatnot. Easy to just add features for the sake of it within proper need or use.
The hardest part
Drag and drop and auto fixing of code issues.
Up next
Not sure, but it will continue to slowly grow and refine for sure.
