SymfonyCon Warsaw: five of us are going

No SymfonyCon has had this many AI talks. David is after the ones that go past the demo. In “Beyond the Demo”, Christopher Hertel shows what AI features built on Symfony AI need in production: human-in-the-loop, long-running workflows, retries and cost tracking. Those are the same questions we work through in client projects.

In “Exposing Your API to AI Agents”, Antoine Bluchet compares ways to open an API Platform API to agents over MCP. We edit our own website through exactly that kind of MCP server. Ramona Schwering explains why a language model's output deserves the same suspicion as any user input (“Why AI Output Is the New XSS”). And Kateryna Dvornichenko asks a question every team will face soon: who reviews code that nobody typed?

In “PHP Wasn't Supposed to Do That”, Felix Eymonot builds iOS and Android apps from a single Symfony codebase with Symfony UX Native and Hotwire Native. That's the pairing we build apps with too, so Liubov wants to see where it hits its limits.

Mathéo Daninos shows AI agents driving Turbo and Live Components through the AG-UI protocol. Matthias Krauser keeps CSS, JavaScript and images right next to the Twig component they belong to. And Gracjan Józefczyk settles the old “headless or monolith” argument with a middle way: Live Components, plus React or Vue inside Twig.

Friday opens with Stefan Koopmanschap and ten small changes in language and behaviour that make a team more inclusive. Florian Margaine tells how technology helped him follow meetings again after fifteen years of hearing loss, and what developers can do for accessibility.

On the technical side, Vira's list has Jordi Boggiano and Nils Adermann on supply chain security in Composer and Packagist, Kévin Dunglas with Mercure 1.0, and Jérôme Tamarelle with encrypted fields you can still query. Plus Rachelle Scheijen, who shows legacy code sharing the Symfony container. That's a route we often take when we migrate old applications step by step.

Björn and Dmitry are coming too. If you'd like to talk about a project, Symfony or running AI in production, drop us a line before the conference. Afterwards we'll write up on the blog what we're taking home.
