If you're writing an application in C or C++ and want to embed a scripting language, and you think Lua is kinda weird and would prefer a more straightforwardly object-oriented language, then Wren may be worth trying.

But I think there is only one active maintainer so you should be prepared to write your own patches if you need to fix something.

I am building tool for generating PDFs (https://docula.app) and I am using Wren to allow user scripts: things like show/hide label on some value or maybe display number in red when the value is > 0 and green otherwise. I was thinking about using Lua, but Wren seems more approachable to me.

I think it got it's start as part of https://luxeengine.com/ which transitioned away from Haxe
