We’ve all been there: integrating a third-party or legacy API and receiving a massive, deeply nested payload—JSON, XML, or SOAP. What follows is tedious manual work: creating Java classes, mapping fields, and writing getters, setters, and annotations. It’s error-prone, time-consuming, and easy to mess up—miss a field, map an array wrong, or introduce a typo, and your parsing breaks.

What could you build with GPT-5.6 that wasn’t practical before?

You can automate things like DTO generation, schema conversion, and API analysis without constant manual fixes. The real shift: less coding, more eliminating repetitive work entirely.

"Hey Hunters! 👋 I built DTO Generator because I was tired of the developer tax. Whenever I integrated a new third-party service or connected to a legacy SOAP endpoint, I found myself spending 15 minutes manually copying fields, formatting them to camelCase, writing nested sub-classes, and adding standard annotations. Existing online tools struggled with deeply nested arrays or tripped over enterprise SOAP XML namespaces. ChatGPT was okay, but it frequently hallucinated types or forgot validation imports. I just wanted a fast, deterministic tool in my browser where I could paste a massive payload and get back copy-pasteable, compile-safe Spring Boot Java classes. DTO Generator does exactly that. We’ve also built a side-by-side JSON comparer so you can diff schema changes instantly when third-party APIs update. It is 100% free, runs entirely in the browser, and requires no login. I'd love to hear your feedback—what features or languages (Kotlin, Go, TypeScript) should we support next? Thanks for checking it out! 🚀"
