Watch AI redraw the software stack, in real install data.
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
Everything you need to read software demand.
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.
Demand analytics
Monthly + weekly time series for any package, with CI vs non-CI splits, geography breakdowns, and growth movers across PyPI and npm.
Dependency graphs
Forward fan-out + cohort analysis. Ecosystem clusters discovered via Louvain on the dependency graph — "which packages travel together?"
AI agent
Ask in plain language, get live charts in a split-view workspace. Refine them in conversation, pin the keepers, promote any chart to a tracked alert. The interface adapts to your question — not the other way around.
Watchlists, alerts + ensembles
Pin packages, group them into named ensembles, set threshold rules on growth and get told in-app when one trips. Or just tell the agent to set it all up and approve with one click.
REST API + MCP server
Programmatic access to every metric, with per-tier rate limits and overage billing. MCP tools for Claude Desktop and Cursor (Pro).
Dependency vulnerability audit
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.
Ask the question, not the package.
A registry API returns one package at a time over a short recent window, with no search and no ranking. EnsemblAI is built for the questions that need the whole ecosystem at once.
“Which AI/ML packages grew fastest this quarter?”
Ranked across 5.3M packages by growth, downloads, stars or quality — with 41 filters to narrow it. A registry has no search and no ranking.
Ask it“How is all of AI/ML trending — as one curve, not 40,000?”
Whole-segment series: all 20 domains and 80 categories carry their own multi-year aggregate. One call, not a warehouse project.
Ask it“What does Google — or Anthropic — actually publish, and how much of it is used?”
2,900+ companies and 42,312 GitHub orgs mapped to their packages, with combined totals and domain mix.
Stop navigating dashboards. Start asking questions.
Most data platforms hand you a fixed UI built for someone else’s use case — then charge an enterprise premium for the API to escape it. EnsemblAI builds the analyst into the product: ask in plain language, get real charts on live data, refine them in conversation, and keep what matters. Access is the baseline. Answers are the product.
Live artifacts, never stale
Charts render from a query, not a snapshot — every reopen re-fetches current data. Five chart modes, series toggling, weekly granularity on Pro.
Workspaces that persist
Up to 10 named workspaces. Conversations, pinned charts, and context survive every session — pick up Friday's analysis on Monday.
Any chart → tracked alert
One click promotes an artifact into a threshold rule, evaluated hourly, delivered in-app. The chart you liked becomes the trend you watch.
Acts only with your approval
“Add these to my watchlist.” “Alert me at +10% MoM.” The agent prepares the change; nothing happens until you confirm it.
Monthly billing, no annual lock-in.
Free tier is free forever. Paid tiers prorate mid-cycle changes and include a soft overage cap so you can’t get a surprise bill.
