About

Helping you make more informed decisions about the software you use.

Libraries.io indexes data from 9,305,266 packages from 32 package managers. We monitor package releases, analyse each project's code, community, distribution and documentation, and we map the relationships between packages when they're declared as a dependency. The 'dependency tree' that emerges is the core of the services that we provide.

Search

Spend your time including, not searching.

Search 9,305,266 packages

The majority of publication and distribution channels do not provide sufficient tools for developers to discover packages that could be valuable to them. Similarly they do not provide adequate information for individuals to judge the merit of one package over another when they tackle similar issues or solve similar problems.

Monitor Your Packages

Keeping a watch while you work.

Start monitoring your repos

The software we depend upon is constantly shifting and in need of continuous monitoring and management. By analysing packages and understanding the relationships between them, we can automate much of this.

Similarly we can help you maintain your open source package by reflecting the state of the ecosystem back at you. Exposing the network of consumers who depend upon your software and the characteristics of the packages your software is deployed within.

Get Release Notifications

Smooth out version bumps.

Sign up, it's free for Open Source

Libraries.io tracks releases from 9,305,266 packages on 32 package managers in one place. Subscribe to a package and receive notifications of new versions or tags for platforms like Bower and Go that don't store release information centrally.

Supported Package Managers

Libraries.io supports the following package managers. For more detail check out our compatibility matrix.

What About Package Manager X?

Some package managers require compilation before parsing their dependencies, some we simply haven't got around to yet. Luckily Libraries.io is an open source package so if you need to add a new package manager then you can. You can find everything you need to get started in our documentation.

Why Are You Doing This?

Improving the quality of all software.

Our goal is to raise the quality of all software, by raising the quality and frequency of contributions to free and open source software; the services, frameworks, plugins and tools we collectively refer to as libraries. We do this by tackling three problems:

• Discovery: Helping developers make faster, more informed decisions about the software that they use.
• Maintainability: Helping maintainers understand more about the software they depend upon and the consumers of their software.
• Sustainability: Supporting undervalued software by highlighting shortfalls in contribution and funneling support to them.
