EnsemblAI tracks demand across PyPI and npm — every package, every corporate maintainer, every download trend. See which frameworks, SDKs, and agent toolchains the industry is actually adopting — and what they’re displacing — with watchlists, alerts, ensembles, and a REST + MCP API on top.
Free tier · no credit card · 5 watchlist packages, 12 months history
Install-level download data across two registries, enriched with corporate ownership, license, and industry domain — exposed through a dashboard, a REST API, and an MCP server.
Monthly + weekly time series for any package, with CI vs non-CI splits, geography breakdowns, and growth movers across PyPI and npm.
Forward fan-out + cohort analysis. Ecosystem clusters discovered via Louvain on the dependency graph — "which packages travel together?"
Pin the packages you care about, set threshold rules on download growth, get notified via email, webhook, or in-app.
Compare packages side-by-side as named groups. Save searches, build cohorts, slice by industry domain or corporate maintainer.
Programmatic access to every metric, with per-tier rate limits and overage billing. MCP tools for Claude Desktop and Cursor (Pro).
Upload a requirements.txt, pyproject.toml, or package.json + lockfile and we scan every entry against OSV.dev for known CVEs. Full audits on Pro.
Free tier is free forever. Paid tiers prorate seat changes and include a soft overage cap so you can’t get a surprise bill.
