In one line: Google Lighthouse audits on every theme template of a client store, translated into Shopify-specific fixes (app embeds, images, theme settings), with an exportable fix plan your developers or their AI tools can act on. The diagnostic is ours; the implementation revenue stays yours.
Why agencies use it
- The audit writes itself. What a developer spends 2 to 3 hours turning into client language, the app produces in under a minute: scores, Core Web Vitals, every failing audit with the Shopify-native fix, and the measured time saving.
- Template coverage, not page counts. Shopify renders every product through one template. The app audits one representative page per template (home, product, collection, page, article) picked from the sitemap, or pinned by you, so five audits cover the whole theme honestly.
- Zero access scopes. Nothing to clear with the client: the app requests no OAuth scopes, reads no store data, and never touches the theme. It measures the public storefront through Google's own API.
- Proof for your retainer. Re-audit after your fixes ship and the trend charts document the win, in the client's own admin. We measured 269 Shopify stores: the median mobile score was 48, so the before/after is usually dramatic.
- An AI-ready handoff. Every audit exports a
CLAUDE.mdfix plan that an AI coding agent applies to a theme copy, which your team reviews and publishes. Your juniors ship senior-looking speed work.
The launch-partner arrangement
While the app is new, accepted agencies and freelancers get Pro free on client stores through a private plan, in exchange for honest feedback on what the reports get right and wrong for agency workflows. No contracts, no volume commitments; if the app stops earning its place, uninstall it.
To join, email bkocdur@gmail.com with your agency name and roughly how many client stores you manage. You will get a reply from the developer, not a ticket queue.

Common questions
Does it need access scopes on my client's store? No. Zero OAuth scopes; it measures the public storefront and reads only its own subscription state.
Can I hand the report to clients? Yes. The report and the exported fix plan are plain documents; use them in your deliverables. Implementation and billing stay yours.
What does it cost outside the launch program? First 3 audits free per store, then Pro at $9/month per store with weekly automatic audits, unlimited on-demand audits, and template coverage.
