Libraries.io is an open source discovery service that indexes millions of packages across 32 package managers, letting developers search and track open source libraries and their dependencies. The repository contains the Ruby on Rails application powering the website and its free public data API.
Use cases
- find open source libraries for a task
- search packages by license or language
- track dependencies of projects I rely on
- get package metadata via an API
- discover trending or popular open source packages
- monitor new releases of packages I depend on
When to choose
- you need a searchable index of packages across many package managers
- you want package metadata through a free REST API
- you want to self-host an open source package discovery service
When to avoid
- you need curated, validated package security data for enterprise decisions
- you only need packages from a single ecosystem's native registry
- you need high-volume API access beyond the 60 requests/minute rate limit
