Looks interesting. For me I settled on JTE as the go-to template engine for Java. For anyone curious: https://jte.gg @freakynit - have you seen this one before? how's it compares with Blueprint?

Powerful. But I absolutely adore nunjucks syntax and how easy it is to extend it. Hence, I built Blueprint to give me that same feel in Java.

I have used this btw, professionally :)
