This is always my go-to tool when I'm trying out RegEx!

Beautiful! I tried it with a particularly nasty regex from a codebase I had and it did a fantastic job explaining what it would target. It's similar to regex101.com in a lot of ways, but the UI might be a little more easy to read and understand.

I usually prefer https://regexper.com/. Especially when trying to make sense of regexes I come across in code I didn't write.

I prefer regex101.com because that site assigns different colors to different capture groupings. I made a previous comment on this and why it's helpful: https://news.ycombinator.com/item?id=9581692

(For some reason RegExr.com is submitted to HN much more often than regex101.com. Is there a compelling advantage to RegExr that I've overlooked?)

I love this tool. I have customized Emacs keybindings that open RegExr in a xwidget-webkit instance, type in regexes, and exit RegExr with the regex inserted at the cursor.

Great for reading monstrous regexes or sharpening my regex skills.

I've been using this website for years. It's been so long now that I can't even remember when Grant Skinner, the former Flash/ActionScript guru, released it. Nice to see it shared here.

For ruby regex, I use https://rubular.com/

Actually I use it for all platforms, and it works most of the time. If I notice that something is odd because the regex engine is different, then I'll use something else. But I really value Rubular's UI simplicity.

I prefer regex101 too. I think it has fewer features, but it has the right features and is so easy to approach.

I’m a big fan.
