If you have uv installed, you can test it without installing by running:

  uvx ty check

Here's what I got against one of my larger open source projects:

  cd /tmp
  git clone https://github.com/simonw/sqlite-utils
  cd sqlite-utils
  uvx ty check

Here's the output: https://gist.github.com/simonw/a13e1720b03e23783ae668eca7f6f...

Adding "time uvx ty check" shows it took:

  uvx ty check  0.18s user 0.07s system 228% cpu 0.109 total

I'm not sure if it's using your environment correctly, or are you expecting ~150 errors? Lots of import errors, and I'm guessing most of the other ones are errors because it couldn't infer what was imported.

how does it compare against mypy? is it much faster?

You can also install it "globally" for your user with:

  uv tool install ty

Then you can use it anywhere

  ty check

Can also do

   uv tool run ty

If your $PATH sucks

Damn that's fast. And zero issues in this project with pyright so curious that these are...

There's a good chance many of the errors we emit are incorrect, at this stage. Lots to do still!
