npm & PyPI Package Stats, Downloads & Release Monitor

Get npm and PyPI package versions, release dates, downloads and licenses in bulk, with no login, no browser and no code. Export to JSON, CSV or Excel, or use the API.

Get structured stats for npm and PyPI packages from the official registry APIs: latest version, release dates and cadence, weekly and monthly downloads (npm), license, dependencies, maintainers, repository and deprecation status. You can also pull the top npm packages for any keyword. Turn on monitor mode to get alerts on new releases, deprecations, license changes and maintainer changes.

Use cases

• Devtool companies tracking their own and competitors' adoption week over week
• Open-source and security teams spotting abandoned packages (daysSinceRelease) and license drift
• Investors and analysts scouting fast-growing libraries
• Building comparison tables ("best X library") with real numbers

Input

npmPackages, pypiPackages, npmSearch + searchLimit, monitorMode, onlyChanged.

Output

One row per package: ecosystem, name, latestVersion, latestReleaseAt, daysSinceRelease, versionCount, releasesLast90d, downloadsLastWeek, downloadsLastMonth, license, repository, deprecated, maintainers, dependencyCount, dependencies and more. Monitor mode adds changed, changes and downloadsWeekChangePct.

Maintainer emails are never output. PyPI download counts aren't in the PyPI API and are left out.

Pricing

Pay per result, with no monthly rental or subscription:

• Package record: $0.002
• Package changed (monitor): $0.005

Example: 1,000 results cost about $2.00 in fees. Apify's free plan includes $5 of monthly credit, which is enough to test this Actor.

FAQ

Do I need an account, cookies or a login for the source site? No. npm & PyPI Package Stats, Downloads & Release Monitor uses public data sources only, so there is nothing to connect and no account to risk.

How much will a run cost? You pay only for results delivered (see Pricing above), plus Apify platform usage, which the free plan's monthly credit easily covers for test runs. Start with a small limit to see the exact cost per run.

Can I export to CSV, Excel or Google Sheets? Yes. Every run's dataset can be downloaded as JSON, CSV, Excel, XML or HTML, or pushed to Google Sheets, Make, Zapier, n8n, Slack or a webhook through Apify integrations.

Can I run it on a schedule or from my own code? Yes. Add an Apify Schedule (hourly, daily, weekly) or call it through the Apify API / Python & JavaScript clients. It also works with AI agents through the Apify MCP server.

What happens if an input is invalid or a source is down? The run keeps going. The bad input gets a row with an error field so you can see what failed, and you are not charged for results that were not delivered.

Is this legal to use? It collects publicly available data. You are responsible for using the output in line with the source's terms and privacy laws such as GDPR/CCPA; don't use it for spam.
