📦 Libraries.io Package Scraper

🚀 Pull package intelligence across 31 registries. Search a keyword or list exact packages and get SourceRank, stars, dependents, and license data for each one.

🕒 Last updated: 2026-06-02 · 📊 26 fields per package · npm, PyPI, Maven, Cargo, and 27 more · keyword or package input

Collect open source package metadata from Libraries.io, the cross-ecosystem index of 31 package managers. Search by keyword or pass exact packages, and for every project get its SourceRank, stars, forks, dependents count, latest release, license, keywords, and repository link.

Coverage: npm, PyPI, Maven, Go, NuGet, Packagist, Cargo, RubyGems, CocoaPods, Hex, Conda, CRAN, CPAN, and more. Search across all of them or filter to one.

📋 What the Libraries.io Package Scraper does

• Searches packages by keyword across every supported registry.
• Looks up exact packages by "platform/name" with no key needed.
• Returns 26 structured fields per package, including SourceRank.
• Captures stars, forks, dependents, and dependent repos.
• Flags deprecated packages with a status and reason.
• Exports to CSV, Excel, JSON, XML, or via API.

⚙️ Input

Example 1: keyword search

{
"searchTerms":["http client"],
"sort":"rank",
"maxItems":50
}

Example 2: exact packages

{
"searchTerms":[],
"packages":["npm/react","pypi/django","cargo/serde"]
}

⚠️ Good to Know: keyword search uses the Libraries.io API and a shared key ships by default. Exact package lookups work without any key. The status and deprecationReason fields fill in only for deprecated or removed packages.
