npm Scraper – Package Downloads, Dependencies & Maintainers

Export npm package metadata (version, license, repository, maintainers, dependencies) plus weekly and monthly download counts, by package name or search query. Official registry API.

npm Scraper by Moxie: fast, reliable and polite, built on official/public data sources.

What can it do?

• Market maps of JS libraries and competitors
• Developer-tool lead generation via repository links
• Supply-chain / license audits
• Tracking adoption with scheduled runs

Data source

The official npm registry (registry.npmjs.org) and downloads API (api.npmjs.org). Public data only.

Features

• Pay only for results (pay-per-event pricing, no monthly rental)
• Incremental mode: scheduled runs return only items you haven't received before
• LLM-ready output: optional compact Markdown per item for RAG / AI agents
• Polite rate limiting with automatic retries and backoff
• Clean, flat JSON you can export as CSV, Excel, JSON or via API
