## Details

JOptimize is a native IntelliJ plugin built for Java developers who want to catch the issues that actually take applications down in production. While SonarQube is great for general code quality, JOptimize goes deeper on Java-specific patterns — JPA, Hibernate, concurrency, and architecture — detecting N+1 queries, memory leaks, circular dependencies, and layer violations in seconds, right inside IntelliJ. It works with Spring Boot, Quarkus, Micronaut, Wildfly, Jakarta EE, and any Java project, with no configuration and no upload required.

Your code never leaves your machine. JOptimize analyzes everything locally, so there is no context switch and no browser tab — issues are highlighted directly in your code as you type. A gutter icon opens an AI explanation with a ⚡ Fix button that calls Claude AI to explain and fix the problem in click. An Architecture Audit tab surfaces circular dependencies and layer violations, and results can be sent to a dashboard for history and trends. JOptimize works with IntelliJ IDEA Community and Ultimate.

JOptimize complements SonarQube — it doesn't replace it. Use both. Where generic tools stop at general code quality, JOptimize targets the Java and JPA patterns they miss: N+1 query detection for JPA/Hibernate, @Transactional anti-patterns, Spring AOP proxy self-invocation that bypasses @Cacheable, RestTemplate without timeout detection, missing readOnly transactions on queries, field injection anti-patterns, unbounded queries without pagination, architecture circular dependencies, Controller → Repository layer violations, God class and complex class detection, and hardcoded secrets with OWASP Top 10 coverage. Unlike PMD or SpotBugs, JOptimize brings AI-powered fixes directly into IntelliJ with click.

Pick what you need — or run all three. Deep static analysis targets Java and JPA patterns that generic tools miss across Spring Boot, Quarkus, Wildfly, and Jakarta EE. Detection covers N+1 queries, save()/deleteById() in a loop, and unbounded findAll(); Spring AOP proxy self-invocation for @Transactional and @Cacheable; RestTemplate and @Scheduled blocking the scheduler thread; OWASP Top 10 with full Java coverage and hardcoded secrets; plus regex/split in loops, List.contains() O(n²) patterns, and mutable Date in beans. Architecture Audit helps you understand how your codebase is structured before it becomes unmaintainable, with pattern detection for Layered and Hexagonal architectures, circular dependencies between packages, layer violations such as Controller → Repo direct access, God class and complex class detection, and AI recommendations for target architecture.
