The front page says:
"NoSQL? Kirby Prefers NoDB!
Kirby is file-based – No database involved. This means first class performance,
version controllable content, simple backups and many other awesome sideeffects."
What other "awesome" sideeffects? I tried the link and found only a download page. I also scanned threw the documentation and found no further statements and no explanation.Seams to me, that the claims are just made without any explanations or prove. Sad.
Edit:
The claims are nice, but many of those are rather thin. For example, content in a database is also version controllable. I see no substantial advantage here in content on the file system.
