CascadiaJS 2025 is coming BACK to Seattle, WA and will run from Sept 17 - 20. We'll host a Welcome Reception on Sept 17, have 2 days of talks on Sept 18 and 19 and get out and about the Seattle area for a day of activities on Sept 20!
Our venue is a beautiful historic building located within walking distance of downtown, Capitol Hill, and several light rail stops.
You’ll hear from a diverse lineup of speakers covering everything from the latest in web and JavaScript to the interaction of web technologies and AI.
Take advantage of breaks, meals, evening events and organized ice breakers to meet people, connect and grow your network!
Your full conference ticket includes a welcome reception, 2 days of light breakfast & lunch, all day coffee, and a closing party with dinner.
From our Scholarship Program to hosting CascadiaJS in an accessible venue, our goal is to make this event available to as many people as possible and build an inclusive community for web developers.
Our Expo Hall will be filled with many of the top companies building tools in the web and AI space. Stay tuned for more updates on who will be exhibiting this year!
If you live in Portland, OR or Vancouver, BC there is no better way to get to CascadiaJS than to join your fellow devs on the Hacker Train. Ditch the car, make some friends and fork repos on the train Wi-Fi as you head to Seattle.
We’re continuing our annual tradition of closing out the conference with an epic night of karaoke, and we’ve hired one of the PNW’s best karaoke DJs to help us do it. Don’t miss it!
On the Saturday after the conference, we're going to organize some activities so that folks can explore the Seattle area, get some fresh air and have some fun!
I LOVE CascadiaJS. Incredible conference in a beautiful city with solid lineups, wonderful staff, and just the right amount of silly. Also @crtr0 at karaoke. 💙

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.
