Typedframes – Pandas/polars column name checking at lint time

Typedframes is a Python devtool that adds static type checking for Pandas and Polars DataFrames, catching column name errors and type mismatches during linting rather than at runtime. It is designed for data scientists and engineers who want the safety of typed code without abandoning the flexibility of DataFrame libraries. The project is interesting because it bridges the gap between dynamic data analysis and robust software engineering practices, preventing silent bugs in data pipelines.
