+1 for Processwire! I’ve mentioned it here a few times over the years and nobody seems to have ever heard of it! I’ve got a few sites well past 10 years now still happily chugging away on it! Basically zero issues with it, ever. It’s still my go to for all sorts of projects - installs in a few seconds, loads of really useful functionality out the box, easy API, beautifully flexible for all sorts of projects and a great community and ecosystem around it as well!
