About this event

performance.now() is a single-track web performance conference at the Oosterkerk on 19 and 20 November. Talks cover JavaScript and CSS performance, framework performance, performance budgets and culture, perceived performance, monitoring and compression. The 2026 line-up includes Harry Roberts, Tim Kadlec, Pat Meenan, Tammy Everts, Jeremy Keith, Scott Jehl and Stéphanie Walter, with Robin Marx and Jason Pamental as MCs. Day 1 starts at 09:30. Tickets start at 700 euros plus VAT, and a live stream is offered. Why go: many of the best-known names in web performance on one stage, and single-track means everyone sees everything. Best for front-end and platform engineers with a performance budget to defend.
