No limits. Completely free.</p> <h2> Try it </h2> <p>👉 <a href="https://javaflow.tools" rel="noopener noreferrer">https://javaflow.tools</a></p> <h2> What's next </h2> <p>I'm thinking about adding more tools for Java/Spring developers — things like <br> XSD to Java, SQL to JPA entities, or OpenAPI generator.</p> <p>What would actually save you time? Drop a comment, I'm all ears.</p> java productivity showdev tooling
