Rich created Svelte and continues to shape the framework, its compiler model, and the developer experience around it.
Svelte educator and ecosystem contributor
Paolo Ricciuti
Talk: Computer, build me an App (v2026)
Paolo teaches Svelte and SvelteKit through practical examples, community education, and hands-on developer material.
Svelte framework developer
Stanislav Khromov
Talk: Building a new Svelte meta-framework in the age of AI
Follow the making of Mochi, an islands-based Svelte meta-framework, and explore hydration trade-offs, Bun’s bundler, and how AI changes the way frameworks are built and used.

Talk: Page, unbound -- Tools for writing beyond text
opperpinguïn
Speaker
Carlos Ivanchuk
Talk: Building an OS in the browser, the Svelte Way
Explore the browser primitives behind a progressively enhanced OS, from isolated apps and shareable URLs to an offline-first sync engine powered by runes and SvelteKit remote functions.
Speaker
David Peng
Talk: One Document, Many Projections: A Svelte 5 Architecture for Humans, Multiplayer, and AI Agents
See how one shared document and Svelte 5 reactivity can power a collaborative editor where people, teammates, and AI agents write through the same command path.
Speaker
Yuichiro Yamashita
Talk: Svelte and oxc: Where Things Stand, and Where They Could Go
Look inside Svelte’s tooling pipeline and its relationship with oxc and Rolldown, with benchmarks and lessons from a Rust port of the compiler, formatter, and linter.
Speaker
Nils Röhrig
Talk: What if your SvelteKit app didn't depend on SvelteKit?
Learn how Hexagonal Architecture can keep business logic independent of SvelteKit, using remote functions as adapters, and explore the benefits and complexity this approach brings.
Speaker
Jeppe Reinhold
Talk: Your Agent Doesn’t Know Your Components
Explore how Storybook can give coding agents component knowledge, help them test Svelte UI in isolation, and bring developers into a focused review workflow.
Speaker
Raphaël Améaume
Talk: Fragment, a modern toolkit for creative coding
Step inside Fragment, a creative coding toolkit built with Svelte and Vite, from automatically generated controls and shader reloading to shareable sketches and in-browser video export.
Speaker
Elliott Johnson
Talk: Dreams of Streams
Dive into Svelte’s upcoming streaming server-side rendering, sending an initial page to the client and streaming in boundary contents as they resolve on the server.
Speaker
Stephane Vanraes
Talk: Breaking the Boundary: Reactive Shared Memory in Svelte
Explore how SharedArrayBuffer and Atomics can make shared state feel reactive across Web Workers, moving heavy work off the main thread while keeping changes connected.
