1. Create your workspace

Head to app.cairn-script.com/register and sign up with email or Google. Your first workspace is created automatically.

​
2. Connect Webflow

From the workspace dashboard, click Connect Webflow and authorize Cairn against the workspace whose sites you want to manage. Cairn will list every site you have access to.
You can connect more than one Webflow workspace per Cairn team — useful for agencies juggling client accounts.

​
3. Install the loader

Pick a site and click Install loader. Cairn writes a single <script> tag into the site’s project-level Webflow settings through the Data API. That’s the only thing you need to embed. Read the install-loader guide →

​
4. Write a script

Click New script to open the paired editor:
  • JS runs on the live site after page load.
  • CSS is injected into the document head.
  • Both versions are written and shipped together.
Save when you’re ready — your draft is held server-side until you publish.

​
5. Publish

Hit Publish and the loader picks up the new version on the next page load. No Webflow republish needed.
That’s it. Open the live Webflow page and watch the script run.
