API Completeness

Narwhals has two different level of support for libraries: "full" and "interchange".

Libraries for which we have full support we intend to support the whole Narwhals API, however this is a continuous work in progress.

In the following section it is possible to check which method is implemented for which class and backend.

Info

  • By design, Polars supports all the methods of the Narwhals API.
  • "pandas-like" means pandas, cuDF and Modin.
