Who is behind EnsemblAI

EnsemblAI is built and operated by EnsemblAI LLC, a Wyoming limited liability company.

What it measures

Download activity, growth, dependency structure, corporate ownership and GitHub health for every package on PyPI and npm, pre-computed across the whole ecosystem so a question like “which AI SDKs are actually being adopted” is one call, not a warehouse job. The download basis and its limits are written up in How we count downloads.

Where the data comes from

PyPI: the Python Software Foundation’s public download logs in BigQuery, the same source behind PyPI’s own statistics.
npm: the registry download API, reconciled against the registry’s per-package counts.
Metadata: the registries, GitHub, and a classification layer that tags packages by industry domain and technology category. Where a value is model-derived, the API says so.
