Browser Synchronization
Use many browsers at once — Chrome, Safari, Firefox, Desktop/Mobile — and keep them in sync during development:
- ✅ Actions synced across browsers (input, click, scroll, etc.)
- 🔁 Automatic browser refresh when you edit code

Make sure Docker is installed, then run:
docker run -d --name powersync -p 8080:80 ghcr.io/explodinglabs/powersyncInsert the following snippet (generally before the </body> closing tag, in
certain cases it only works in <head>):
<script
id="powersync"
type="text/javascript"
data-events-uri=":8080/.well-known/mercure"
data-events-topic="powersync"
src="https://explodinglabs.com/powersync/powersync-0.1.0.js"
></script>DOM events like input, scroll, and clicks will now sync across browsers.
After building your site, notify browsers with an HTTP request:
curl -X POST http://localhost:8080/.well-known/mercure \
-H 'Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJtZXJjdXJlIjp7InB1Ymxpc2giOlsiKiJdfX0.PXwpfIGng6KObfZlcOXvcnWCJOWTFLtswGI5DZuWSK4' \
--data-urlencode topic=powersync \
--data-urlencode data='{"type": "refresh"}'| Type | Description |
|---|---|
| refresh | Reloads the entire page |
| css | Reloads all external stylesheets |
| js | Reloads all external JavaScript files |
