Lighthouse CI is Google's open-source tool for running Lighthouse audits inside continuous integration pipelines — perfect for blocking deploys that regress Core Web Vitals. StoreVitals is hosted health monitoring built for ecommerce store owners who don't have a CI pipeline. Different tools for very different workflows.
Lighthouse CI and StoreVitals address different stages of the same problem. Lighthouse CI is a build-time gate for engineering teams: 'don't let this pull request ship if it regresses performance.' StoreVitals is a runtime monitor for store owners: 'tell me when production health degrades, regardless of how the code got there.' Engineering teams with CI pipelines should use Lighthouse CI to prevent regressions; store owners without engineering resources should use StoreVitals to catch problems that escape any pipeline (third-party app updates, content changes, infrastructure shifts). The most mature setups use both: Lighthouse CI in CI for prevention, StoreVitals in production for monitoring.
