How to See a Preview Before Publishing in Webflow (And How Gapflow Ensures Forms Work Perfectly Live)

Designing a site in Webflow? Before you hit “Publish,” it’s smart to preview your changes — not just visually, but functionally. A polished preview helps catch layout issues, content errors, and form bugs before your users do.

In this guide, we’ll walk you through how to see a preview before publishing in Webflow, and introduce you to Gapflow.io — a form automation platform that ensures your forms behave perfectly after you go live.

✅ How to Preview in Webflow (The Right Way)

Webflow makes it easy to see your site before publishing. Here’s how:

🖥 1. Use the Webflow Designer Preview Mode

• Click the eye icon in the top toolbar.
• This lets you view your site as it would look live, with real layout responsiveness.
• Note: Forms won't functionally submit here — this is just visual.

🌐 2. Publish to a Staging Domain

• Click “Publish” to your-site.webflow.io.
• This is the best way to preview real functionality like form submissions, animations, and interactions.
• Test across devices and browsers using this live staging site.

📱 3. Use Webflow’s Built-In Responsive Views

• Inside the Designer, toggle between Desktop, Tablet, and Mobile.
• Great for layout tweaks, but always follow with a staging test.

🔁 4. Preview Interactions and Animations

• Use the preview mode to test animations, scroll effects, and dynamic visibility rules.

🚨 What Previews Don’t Tell You: The Form Functionality Gap

Even if your site looks perfect in preview or staging, Webflow’s native forms lack automation, filtering, and confirmation features. Once you're live, this leads to:

• Missed form submissions
• No autoresponders
• Spam inbox overload
• Manual sorting of job vs. sales leads

That’s where Gapflow.io comes in — to make sure your forms work just as perfectly as they look.
