Score: 6.7/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

Jolta is a Java version manager that uses shims to automatically switch JDKs per project based on .java-version files, similar to Volta for Node.js. It stands out by setting JAVA_HOME automatically, supporting auto-download of missing JDKs, and providing enterprise features like corporate mirrors and air-gapped updates, addressing long-standing pain points in Java development.

Target audience: Java developers, backend developers, DevOps engineers
