Question Ranking
Pros
Pro Simplicity
It's simple design and lack of more advanced C++ features makes it easy for beginners.
Pro Fast
Well-designed widgets, coded with careful attention to rendering/execution speed.
Pro Stable
FLTK code developed more than 10 years ago still compiles and runs perfectly, without changes.
Pro Lightweight
Uses a limited and lightweight design and restricts itself to solely GUI functionality. Because of this restriction, the FLTK hello world example is only about 100 KiB.
Pro GUI designer
Fast Light User-Interface Designer (FLUID) included.
Pro Easy to use
Easy to make compiled native apps.
Cons
Con Can be too simple for some projects
FLTK offers far fewer widgets than most other toolkits.
Con Does not look like a native application
Because it uses non-native widgets, it doesn't look like a native application on any platform.
Con Subscription-based/Not free
Using this product you're betting the company will still be around. If they get bought out by an enterprise that wants to use the tech internally, all they need to do is stop offering subscriptions and suddenly you're scrambling to rebuild your entire app on other technology.
Con No Android support
They plan to eventually support Android, but for now, they only support iOS.
