Use our Universal Package Manager.
A package manager for every language. Don’t think about yarn, npm, maven, or poetry. UPM saves you a headache by running a package manager for whatever language you’re using.
Automatic installs. Just import and press run. UPM will automatically detect what packages you need just from your code, without having to install packages manually.
