Is JOptimize really free?

Yes. The IntelliJ plugin is 100% free and detects 80+ performance and security issues with no API key and no sign-up. The Pro plan adds AI-powered fix suggestions, architecture audits, and live profiling.

Does my code leave my machine?

Never. The plugin analyzes your code entirely inside IntelliJ with no source code uploaded. If you use the web dashboard to upload a JAR, only the compiled bytecode is processed and deleted immediately after analysis.

How is JOptimize different from SonarQube?

SonarQube focuses on general code quality like naming and complexity. JOptimize catches Java-specific runtime issues that SonarQube misses: N+1 queries, memory leaks, blocking calls in reactive pipelines, Spring Boot misconfigurations, and architecture violations.

What Java frameworks are supported?

JOptimize supports Spring Boot, Quarkus, Micronaut, Wildfly, Jakarta EE, and any standard Java project. The plugin works with Java 8 to 21+, including virtual threads and record patterns.

Can I cancel my Pro subscription anytime?

Yes, you can cancel anytime from your dashboard with no contracts or cancellation fees. Pro access remains active until the end of your billing period.

What it is

Screenshot of the JOptimize homepage — joptimize.io, as visitors see it

JOptimize is an integrated Java analysis platform built into IntelliJ that catches runtime issues missed by traditional code quality tools. It detects N+1 queries, Hibernate anti-patterns, Spring misconfigurations, memory leaks, OWASP Top 10 vulnerabilities, and architecture violations like circular dependencies and layer violations.

The tool offers four analysis modes: a real-time IntelliJ plugin with AI-powered fixes, GitHub/ZIP upload for quick audits, a local CLI for privacy-conscious teams, and a JVM agent for live runtime profiling. All analysis can run completely locally with no code upload required.

JOptimize covers Spring Boot, Quarkus, Micronaut, Wildfly, Jakarta EE and standard Java projects from Java 8 to 21+. The free plan includes 80+ detection rules and performance/security analysis. The Pro plan adds architecture audits, live profiling, AI summaries, and unlimited analyses.
