At Slack we have an internal Rust-based Hack typechecker that’s about 20% faster than the OCaml one (we use both)
Did you see better speedups over Pyre? Aka did I leave stuff on the table…

Hack is quite a bit more optimized than Pyre was, but Pyrefly is at least 10x faster than Pyre on the IG codebase.
I didn’t know about the Rust-based Hack checker— that’s really cool!
