Still writing tests with extra wrapper steps and inherited test classes?

Vaadin 25.2’s new Browserless API moves to a cleaner locator-based approach inspired by @playwrightweb, while keeping full-stack #Java testing workflows intact.

AI coding tools are changing how we build software.

But how do you prevent requirements, documentation, and code from drifting apart?

Missed our last webinar?

In part 2 of our AI series for Java devs, we broke down how modern AI workflows actually work –agents, memory, context windows, tools, and where it all tends to fall apart.

Most Swing apps still work.

The challenge is everything around them:
UX expectations, deployment, maintainability.

Start by running your app in the browser.
Then modernize it step by step with Vaadin — while keeping it all in Java.

AI coding tools look great in demos, but real #Java work is complex.

You need more context, agents, integrations, and multi-step workflows.

Join our webinar to see what works beyond prompts and where #AI still needs you.

If you’re still running a #JavaSwing app, you know the pressure. 🤯

Retiring experts. No new talent. UX stuck in 2005.

We put together a practical guide to modernization; your options, how to choose, timelines, and what works.👇
