RegExr
RegExr is a HTML/JS based tool for creating, testing, and learning about Regular Expressions.
For anyone who is afraid of RegExs. I can really recommend regexr.com. That website not only helped me understand it but also helped me solve various otherwise highly complex problems. In my studies, in my real life job and private projects alike. Can recommend and once you understand it, it gets real fun!

Also, regex engines are not created equally, at all. One of the best writeups I've ever read is from the ripgrep blog. Burntsushi knows regex. There's also this benchmark site which illustrates how general language performance is an entirely different metric than regex performance. Don't assume those benchmarks will cover your particular use case, though--different regex engines might handle your particular situation differently.
