Can I check sites built with Bolt, Lovable, or v0?

Yes. Viewpo works with any deployed URL. If your AI-generated site has a public URL (or a preview deploy URL), you can audit it.

How many audits can I run for free?

The free tier includes 50 audits per month at 3 viewport sizes. That's enough for most solo builders. Need more? Pro starts at $19/mo.

You built it with AI. Does it actually work on phones?

Viewpo tells you if your AI-generated site is responsive — in plain English, with specific issues to fix. No DevTools required.

The problems you know too well

You didn't write the CSS

Bolt, Lovable, v0, and Cursor generate code you can't easily debug. When something looks wrong on mobile, you don't know where to start.

"It looks fine on my screen"

Most of your visitors are on phones. You built it on a laptop. That's a problem you can't see until someone else visits.

Your client says it's broken

They send you a screenshot from their phone. You resize your browser. It looks fine. Now what?

How Viewpo helps

The features that matter most for your workflow.

Paste and audit

Paste your deployed URL. Get real browser screenshots at phone, tablet, laptop, and desktop sizes in seconds.

A-F grade you can understand

One clear answer: is your site responsive or not? Share your A grade with clients. Fix the issues behind a D.

Plain-language explanations

"This element is wider than the screen on mobile" — not "overflow detected on `.hero-container`". You don't need to understand CSS.

Shareable report links

Send your client a link to the audit report instead of taking screenshots and explaining what's wrong.

You just built a landing page with Bolt. It looks great on your laptop. But does it work on phones? Paste the URL into Viewpo, get your grade in seconds, fix the overflow issues it found, re-audit, and share the A-grade report with your client. Done.

Frequently Asked Questions

Quick answers to help you decide.
