performance.sync(2026): performance.now() pre-conference meetup

The official pre-conference meetup for performance.now(), sponsored by Mozilla, on the evening before the conference.

Eight short talks from people who build web performance tooling: Annie Sullivan on soft navigations in Core Web Vitals, Patrick Meenan on optimising for performance in the age of AI, Nazım Can Altınova on agentic profiling with the Firefox Profiler, plus Jad Joubran, Estela Franco, Marko Ilić, Dan Gayle and Karlijn Löwik on declarative partial updates, Next.js, DevTools MCPs, LLM-assisted audits and RUM. Drinks and snacks after.

19:00 to midnight at Desmet Studio's, Plantage Middenlaan 4A. Free on Luma.

Why go: the line-up is the people behind the metrics everyone else optimises for, and it costs nothing. Front-end and platform engineers should go even if they skip the main conference.
