I tried it yesterday after a commenter on HN mentioned it, I'm not a front end dev but I still hate how slow and seemingly fragile webpack is. I dropped rspack into a couple of projects and instantly got a 3x speedup with identical output. I love it. Also, apparently it's pronounced "arse pack", what's not to like.

This! It is backwards compatible with many of the older webpack plugins. This makes a migration easier. For me a complete build was 3x as fast.
