- Backend and Java developers
- Worth noticing
- The catalog includes a DST collision simulator, a cron overlap detector, and visualizers for Kafka rebalances and JPA N+1 queries.
Field notes
The catalog is arranged by practical work areas, with a substantial Java section covering Spring configuration, Maven, thread dumps, JDBC, and JVM memory. Its Play section shifts from utility to demonstration, listing visualizers for Kafka rebalancing, JPA N+1 queries, deadlocks, and garbage collection. The homepage claims the tools run in-browser, require no sign-up, and work offline; the extracted page does not independently verify those claims.
