Performance
Know it's fast before launch day.
Run a PageSpeed audit on any preview page, mobile or desktop, without leaving ThemeSync. Every result is kept.
Opportunities
See what to fix, biggest win first.
Each audit lists what's slowing the page down, with the estimated time or size you'd save.
- Scores for speed, accessibility, best practices and SEO
- Core Web Vitals in plain view
- Diagnostics for the deeper dig

Built into the preview
No copying URLs into another tab.
Audits run against the preview you already have, on the pages you already mapped.
Any mapped page
Audit a product or collection template, not just the homepage.
Mobile and desktop
Each is scored on its own, the way Google does it.
5 free audits a day
Add your own Google API key for unlimited runs.
History
Every audit, kept with a screenshot.
Check the score before and after a change, and spot a slip before the client does.
- Re-run any past audit in one click
- Works for WooCommerce previews too
