Should you contribute to facebook/pyrefly?
facebook/pyrefly has a FoundDev health score of 86/100, which puts it in the active-and-maintained tier. The maintainer team is shipping recently, issues are being closed, and a PR you open this week has a realistic chance of being reviewed.
Last push was 0 days ago — that signals an actively maintained project. New issues are likely to get a maintainer response within days. The project is written primarily in Rust, so prior Rust experience will shorten ramp-up.
