  Bytecraft

  The opening keynote. Elena takes the audience on a tour of the web platform's most transformative recent additions — from WebGPU to View Transitions to baseline support for container queries. She live-demos a full-stack application running entirely in the browser and makes the case that the gap between native and web has never been smaller.

  Browser DevTools: Hidden Gems for CSS Debugging

  Lucas Moreau

  Websmith

  Your browser's developer tools contain powerful CSS debugging features that most developers don't know exist. Lucas demos the Flexbox and Grid inspectors, the font editor, the animation timeline, and the container query visualization tools — showing how each one can shave hours off common layout debugging tasks.

  Screen Readers Deserve Better Components

  Naomi Tanaka

  Axion

  Most component libraries claim accessibility support, but the screen reader experience often tells a different story. Naomi demonstrates real-world failures she's found in popular UI libraries, explains why they happen, and walks through the process of building components that genuinely work with assistive technologies across platforms.

  ARIA Patterns You're Probably Using Wrong

  

  Priya Sharma

  Senior Developer Advocate @Cobalt

  Priya works on the developer relations team at Cobalt, focusing on accessibility tooling and standards education. She created the popular 'A11y Myths Busted' video series and contributes to the browser's accessibility auditing rules. Before Cobalt, she worked as a frontend engineer at a leading accessibility consultancy.

  ARIA Patterns You're Probably Using Wrong

  Priya Sharma

  Cobalt

  Well-intentioned ARIA usage often makes interfaces less accessible, not more. Priya walks through the most commonly misused ARIA roles and properties — live regions that fire too often, menu roles on navigation, dialog traps that trap too much — and shows how to audit and fix them using your browser's built-in accessibility tools.

  Profiling React Renders at 120fps

  Ryan O'Sullivan

  //

  Cobalt

  Modern devices support 120Hz displays, but most React apps struggle to maintain 60fps during complex interactions. Ryan demonstrates a systematic profiling workflow using browser DevTools, React profiling tools, and custom performance marks to find and fix render bottlenecks — from expensive selectors to unnecessary re-renders to layout thrashing.

  Type-Safe Design Tokens Across Platforms

  Sarah Lindström

  //

  Tessera

  Design tokens promise a single source of truth, but the reality is messy — different platforms, different formats, different constraints. Sarah presents Tessera's approach to generating type-safe token APIs for web, iOS, and Android from a single token definition, using code generation to eliminate the drift between design and implementation.

  Deploy Preview Environments That Scale

  Tom Kowalski

  Nimbus

  Every pull request deserves a live preview, but spinning up isolated environments for hundreds of daily PRs is an infrastructure challenge. Tom explains how Nimbus's preview deployment system handles ephemeral environments at scale — from instant cold starts and database branching to URL routing and automatic cleanup.
