First thanks for mentioning tach, I wished this tool existed for a long time and I'm happy to give in a try in the following days!

For typechecker, I also vouch for Pyright which is what we use for all our django backends at work.

Just be aware that you will have hard time to typecheck part of your code where you rely heavily on django's magic (magic strings, auto-generated properties/methods, etc...).

In these cases, it's sometimes better to avoid these features entirely or accept that some part of your code will not be typechecked.

I haven't dug into tach yet, but I'm very optimistic on this one.
