Why You NEED This New Python Tool

Get started with Pyrefly: This code looks completely fine — it even runs — right up until it crashes on a line that should never have shipped. Python won't warn you, because it doesn't check types until your code is actually running. In this video I show you Pyrefly, Meta's new static type checker for Python. It's free, it's open source, and it's already running in production at Instagram and PyTorch. I'll show you exactly why Python lets these bugs slip through, why type hints alone don't save you, and how Pyrefly catches these errors before you ever hit run.
