I wouldn't recommend starting any new applications using the Fusebox framework - according to GitHub, it hasn't had any active development in nearly four years. ColdBox would be fine. You should also consider Framework-One (FW/1), which is a lightweight MVC framework by Sean Corfield (who was heavily involved in Fusebox development back in the day).
I think ColdBox is the hands down choice for any new project. The documentation, community, and product are all top notch. They have even recently published a book on the latest platform.
benm36664760 I guess "horses for courses" is apt here. If you want a very lightweight and conventions-over-configurations MVC framework with built-in dependency injection (DI), FW/1 is probably first choice for many. The documentation and example code is pretty good.
If you want lightweight and don't mind configuration so much, then ColdBox Lite is worth considering. It's easy to upgrade from ColdBox Lite to full ColdBox if you need to add in additional capabilities through the other ColdBox modules (WireBox, LogBox, CacheBox, ContentBox, etc.). They have a lot of documentation (some would say too much).
I'm about to start a new greenfield application that is very small. I'm still debating between FW/1 and ColdBox for it.
