| - [pyrefly](https://github.com/facebook/pyrefly) - A fast type checker and language server for Python. | ||
| - [pyright](https://github.com/Microsoft/pyright) - Fast type checker meant for large Python source bases. It can run in a “watch” mode and performs fast incremental updates when files are modified. | ||
| - [pycroscope](https://github.com/JelleZijlstra/pycroscope) - A semi-static type checker for Python code. It imports the modules it type checks, enabling `pycroscope` to understand many dynamic constructs that other type checkers will reject. This makes it possible to extend `pycroscope` with plugins that interact directly with your code. |
