npm & PyPI Package Stats: Downloads, Versions, Licenses

Get clean stats for npm (JavaScript) and PyPI (Python) packages in one run: weekly and monthly downloads, latest version, release history, license, dependencies, repository, homepage and more. Add package names, paste registry URLs, or search npm by keyword. Data comes straight from the official public registry APIs (registry.npmjs.org, api.npmjs.org, pypi.org and pypistats.org). No login, no API key.

Who is it for?

• Developers and tech leads comparing libraries before picking one (popularity, release activity, license, dependency count).
• Developer-tool companies and DevRel teams tracking adoption of their own packages and competitors week by week.
• Security and compliance teams auditing licenses and stale or deprecated dependencies.
• Investors and analysts measuring open-source traction.

How to use it

1. Add npm packages (e.g. express, @types/node) and/or PyPI packages (e.g. requests).
2. Optionally type an npm search like web scraper to add matching packages automatically.
3. Optionally list the recent versions with publish dates.
4. Click Start and download JSON, CSV or Excel, or schedule it to track downloads over time.

Input example

{"npmPackages": ["express", "react"], "pypiPackages": ["requests", "pandas"], "recentVersions": 3}

Output example

{"ecosystem": "npm", "package": "express", "latestVersion": "5.3.0", "license": "MIT", "downloadsLastWeek": 140000000, "downloadsLastMonth": 585410126, "versionCount": 320, "dependencies": 28, "repository": "https://github.com/expressjs/express", "url": "https://www.npmjs.com/package/express"}

PyPI rows also include downloadsLastDay, requiresPython, classifiers and documentation.

How much does it cost?

Pay-per-event: a small fee per package returned, plus a tiny per-run start fee, with no subscription and no separate platform usage costs. For example, 1,000 packages cost about $1. Packages that are not found are not charged. Set Maximum cost per run to cap your spending.

Use it through the API, integrations or AI agents

Run it from the Apify API, on a schedule, or connect it to Make, Zapier, n8n or Google Sheets. AI agents can find and call it through the Apify MCP server. Output is clean JSON with the same fields on every run.

FAQ

Is it legal? Yes. It reads public package metadata from the official registry APIs, at a polite rate. It does not collect maintainer names or email addresses.

How fresh are the download numbers? npm download counts update daily; PyPI numbers come from pypistats.org, which also updates daily.

Can I track downloads over time? Yes. Schedule a daily or weekly run and compare the datasets, or send them to Google Sheets.

Does it support scoped npm packages? Yes, for example @types/node or @angular/core.
