Fresh-brewed for Java

Help yourself to our free OpenJDK binary

At AdoptOpenJDK, our Open Source Artisans work hard to deliver a cost-free, quality-assured binary to run your Java applications. 

Java™ is the world's leading programming language and platform. AdoptOpenJDK uses infrastructure, build and test scripts to produce prebuilt binaries from OpenJDK™ class libraries and a choice of either the OpenJDK HotSpot or Eclipse Open J9 VM. 

All AdoptOpenJDK binaries and scripts are open source licensed and available for free. 

Every stage is open to the public; all the way from our work with Open Source communities, through the rigorous testing pipelines at Adopt's testing CI systems, to the website we publish our binaries on. 

Are our builds any good? Just ask our stats page, which has 60 million downloads so far.

See the magic from conception to delivery: every line of code, every build, every test, and every release. Drop by, and discover what the future of Java holds for you.
