JOptimize detects performance killers SonarQube can't catch — N+1 queries, memory leaks, circular dependencies, and architecture layer violations — directly inside IntelliJ IDEA. No code upload, no configuration. Works with Spring Boot, Quarkus, Micronaut, WildFly, and Jakarta EE. Your code never leaves your machine.

JOptimize is an IntelliJ plugin that detects Java performance, security, and architecture issues that SonarQube misses, running entirely locally.

JOptimize FAQ

Is JOptimize really free?+

Yes, there is a free tier that provides performance and security analysis, the full IntelliJ plugin, dashboard reports and up to three analyses per month.

Does my code leave my machine?+

No, all analysis runs locally; only minimal issue metadata is sent when using the CLI, and source code is never uploaded.

Does it work with Kotlin?+

The documentation does not mention Kotlin support, so it is unclear.

How is this different from SonarQube?+

JOptimize focuses on Java-specific patterns such as N+1 queries, transaction anti-patterns, architecture violations and provides AI-driven fixes, which SonarQube does not cover.

What Java frameworks are supported?+

Supported frameworks include Spring Boot, Quarkus, Micronaut, WildFly and Jakarta EE.

Can I cancel my Pro subscription anytime?+

Yes, you can cancel at any time and the service offers a 7-day money-back guarantee.
