#Pyrefly

2025-05-29

I think #astral may want to consider marketing #ty a bit more.

After a bunch of my coworkers and I got back from Pycon I'm hearing WAY more from them about #pyrefly - which confuses me because while Meta has made MASSIVE contributions to FLOSS and we should all thank them for that, Astral has consistently produced outstanding #python tooling.

I know there's plenty of room in the pool and that competition is good, I'd just hate to see a great tool get overlooked because its competitor was giving away free Espresso :) :P
