alt Hacker NewsThe title of this story should be "Announcing the Beta release of ty". A lot of people have been waiting for the beta specifically.
I've been using Pyrefly and loving it compared to Pyright, but they recently shipped some updates with crash bugs that forced me to pin to a previous version, which is annoying. Unfortunately my first impression of ty isn't great either. Trying to install the ty extension on the current version of Cursor says "Can't install 'astral-sh.ty' extension because it is not compatible with the current version of Cursor (version 2.2.20, VSCode version 1.105.1)."

If there's anything else accompanying the error, do you mind filing an issue? I've been using the ty extension with Cursor for weeks and am having trouble reproducing right now.
Apart from installation problems/crash issues, do you have some feedback about type checking with ty vs. pyrefly? Which is stricter, soundness issues, etc?
Both are rust/open-source/new/fast so it's difficult to understand why I should choose one over the other.
(pyrefly maintainer here) If you haven't already, please file an issue for that crash on the [Pyrefly repo](https://github.com/facebook/pyrefly) as well :)
