Forget everything you know about setting up a PHP development environment. No more complex configurations, Docker permission headaches, or agonizingly slow application cache warmups every time you hit refresh (Sylius, I'm looking at you).

In 2026, FrankenPHP has not only revolutionized production, but it is also totally redefining the Developer Experience (DX) of Symfony.

In this talk, I will show you how we've pushed the boundaries of the application server to offer a fluid, instant, and modern workflow. We will see how to:

* Start a project in seconds:** A simple command is all it takes to get a fully-featured, standalone environment, complete with automatic HTTPS. Whether you are on Linux or macOS, natively on Windows thanks to the bleeding-edge features of Go 1.26, or using the official Symfony Docker stack with Dev Containers, the experience is unified and immediate.
* Get instant feedback (Hot Reloading): Stop hammering the F5 key. FrankenPHP now watches your files and brings true hot reloading to PHP. By dispatching Mercure updates directly to the browser, your app updates on the fly when you change code, just like modern JS frameworks!
* Eliminate load times: Worker mode is no longer just for prod. In dev, it keeps your app hot and instantly refreshes the Symfony cache in the background when you save a file in your editor. The result? Pages that are available dramatically faster, reducing wait times even for the heaviest applications.

As a bonus, we'll even see how this new ecosystem seamlessly integrates with AI coding agents like Claude Code inside a fully autonomous, sandboxed environment.

Join me to discover how the power of Go and Caddy, coupled with the flexibility of Symfony, allows you to focus on what matters: your code.

The future of PHP development is here, and it is lightning fast. 🐘🧟⚡️
