The problem

Millions of companies have poor web performance scores, even though performance is proven to significantly affect business outcomes like revenue, conversion rates, and SEO.

41%
of 12M+ of the most-visited websites have failing Core Web Vitals

Source: Google Chrome UX Report. This sample includes exclusively high-traffic websites. It is very likely that many millions of lower-traffic websites also have failing scores.

How it works

Fits into your existing workflow

Connects via GitHub

Agents connect to your repository and open pull requests. You review, approve, and merge on your terms.

Framework agnostic

Works with React, Next.js, Shopify, WordPress, and any web framework that serves HTML.

Metric-gated deployments

Changes only reach production after verified performance improvement and zero visual or behavioral regressions. Humans review and approve changes at key decision points—consistent with current best practices for production agentic systems.
