Pre-Conf
May 29
We're hosting an AI hackathon leading up to CascadiaJS 2026! Stay tuned for more details, but it will kick-off Friday evening and conclude Saturday afternoon, with the winning team being invited to demo what they built at CascadiaJS 2026!
May 31
Meet up with your fellow hackers for a ride down to Seattle!
Meet up with your fellow hackers for a ride up to Seattle!
The Welcome Reception will be an opportunity for folks to pre-register, get their badge, pickup swag and have fun with our friends from Warp and Whiskey Web and Whatnot.
Want to play a survival game... entirely driven by GitHub issues? Come join Warp and Web Whiskey at the CascadiaJS Welcome Reception! You'll get to play a multiplayer game based on the popular party game Death by AI, backed by Warp's issue triage agents to decide your fate. Can you survive the longest?
Conference
Day One
June 1
Main Track
Hallway Track
Back this year is Cascadia Connect, a set of low-pressure ways to meet cool humans at CascadiaJS. No pressure, no awkwardness—just friendly ways to vibe, learn, and maybe not eat lunch alone.
Connect with folks at the top web + AI companies
Come hang out with us on the official CascadiaJS Discord server! Introduce yourself, ask speakers questions and hopefully make some friends!
Workshop Track
This workshop with Vapi walks through the real execution work behind building enterprise-grade voice agents – from conversation design fundamentals and persona calibration to prompt engineering patterns purpose-built for voice.
This workshop guides you through building a cloud-deployed web research tool for AI coding agents by wrapping Apify's RAG Web Browser with custom LLM-powered query generation and relevance filtering. The finished Actor runs on Apify's platform and gives agents like Claude Code or Cursor access to real-time web data. No Apify experience is needed — just a laptop with Node.js and a coding agent.
Dinner and drinks are included for Premium ticket holders, and there will be a cash bar available as well.
Looking for a new opportunity? Have high-quality conversations with companies that are hiring, like Grow Therapy, Onebrief, RentSpree, Render, Expo, CopilotKit, Warp and more.
Looking to grow your network? Make new friends during a Pog tournament hosted by Mux!

Workshop Track
A workshop on using Render Workflows to handle background jobs without managing queues, retries, or worker infrastructure. You'll build chainable task functions for distributed compute, applicable to workloads like ETL, batch inference, and AI agents. By the end, you'll have a deployed background execution pipeline you can adapt for your own projects.
In this hands-on workshop, you'll go from a minimal agent to a multi-tool, multi-agent system running on Amazon Bedrock AgentCore, with all infrastructure defined as code using Pulumi. You'll build and deploy agents that coordinate tasks, call external tools, execute code, and maintain state over time.
Grab dinner with the new friends you've made at CascadiaJS in Capitol Hill. There are dozens of places to choose from!
We will wrap-up CascadiaJS with an epic karaoke party at Rockbox Seattle. We are buying out the venue and there are 12 different rooms that we can use. Premium ticket holders will be able to skip the line and will be able to bring a plus-one! 🎤🎉
Post-Conf
Training Workshops
June 3
AI is changing how we write code, and you're about to become fluent in these new tools. We'll explore everything from basic AI integration to building sophisticated AI agents that can help with development tasks. Let’s explore everything from AI-assisted coding in your editor to autonomous development with Claude Code.
June 4
Ready to build AI-powered applications? Let's dive into the Vercel AI SDK and modern AI patterns to create intelligent features your users will love. We'll start with the fundamentals and work our way up to building production-ready AI applications.
June 5
Explore everything from basic tool calling to sophisticated multi-step agents that can reason and act autonomously. We'll build a simple agent that can search the web and answer questions, and then we'll add more complex agents that can reason and act autonomously.

i always have a good time at @CascadiaJS. still one of my fave talks of all time there but more imptly the people and the vibe that @crtr0 and co create make you feel the JS community in a way that very very few are able to do.

It’s got everything — a dedicated fan base of 10+ years, close family vibes, long held traditions (the best karaoke!), sublime locale, and a flair for the atypical/creative conf sessions.
Def apply + attend! https://t.co/yqrEbh0icL
The reason why @CascadiaJS is one of my favorite conferences is because you can truly feel the passion and care that everyone puts into it. There's a real sense of community, it's amazing 🙌👏💜

Once again, @CascadiaJS did not disappoint—I love that we have a community-focused conference right in the PNW. It's always inspiring to hear about what people are making, stretch my perspective, and meet new friends.
