Amazon Corretto 2121.0.13.0

Run Java applications and build new Java software on Windows with Amazon Corretto 21, Amazon’s distribution of OpenJDK 21. It provides both a Java SE-compatible runtime for executing applications and a development environment for compiling and creating them.

This LTS release receives ongoing performance enhancements and security fixes, giving teams a maintained Java foundation for production services and long-lived applications. Amazon plans regular updates on a quarterly schedule, with urgent fixes, including security corrections, released outside that cycle when ready.

The current version is 21.0.13.0, and its Java SE compatibility supports applications designed for the standard Java platform. Amazon runs Corretto internally across thousands of production services, which distinguishes it as a distribution used in substantial operational environments rather than only for local development.

The Windows edition supports x64 systems and suits developers, IT teams, and organizations deploying Java services or desktop software on compatible Windows machines. Amazon Corretto 21 is production-ready and includes the OpenJDK runtime and development tools in one distribution.
