PlatformIO Library Manager is a tool for managing libraries of PlatformIO Registry and VCS repositories (Git, Hg, SVN). It makes it exceedingly simple to find, install and keep libraries up-to-date. PlatformIO Library Manager supports Semantic Versioning and its rules.

Search for new libraries in PlatformIO Registry
“1-click” library installation, per-project libraries, extra storages
List installed libraries in multiple storages
List built-in libraries (by frameworks)
Updates for installed libraries
Multiple examples, trending libraries, and more.
