Add reactivity to components using an easy-to-understand event system.
Respond to clicks, drags, hovers, key presses, and more.
Store data, change appearance, modify behavior, and start animations.
Built for individuals.
Start with a small personal project or check out the learning track.
Fully vector rendered.
Every component is constructed entirely with reactive vector graphics.
Share diagrams and visualizations that look great at any scale.
Create interfaces with thousands of nodes without slowing down.
Scales to teams.
Collaborate in real-time and see updates as they happen.
Collaborate in real-time.
Modify everything from appearance to content to behavior together in real-time.
Effortlessly build collaborative tools using simple shared or local state.
Add collaborators or publish your creations with a click.
Try opening the console.
Local-first means you don't even need an account.
A desktop browser supporting WebGPU is required.
Local first and offline enabled.
Work offline; synchronize your work with collaborators when you log in.
Everything you create is stored in your browser.
Keep projects local if you do not need to collaborate.
