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

Introducing #Pyrefly: Meta's new #opensource #Python type checker, crafted in Rust for maximum performance!

Pyrefly is intended to replace the OCaml-based Pyre type checker previously used for Instagram’s codebase.
