Lighthouse Testing Vercel Deployments with Foo Integration

Lighthouse Testing Vercel Deployments with Foo Integration

With Foo's Vercel Integration, you can monitor performance, SEO and page quality via Lighthouse of your production deployments automatically.

Foo's Vercel integration does the following:

  • On every successful Vercel production deployment, Foo will run both mobile and desktop Lighthouse audits against all pages you've added on Foo matching the production domains you've specified during setup.
  • Results of each Lighthouse audit are persisted to your account and surfaced in historical timelines of scores for each page. See the demo's for a full picture. In the timeline chart each Vercel deployment will be displayed as a marker and annotation of the deployment. This way, if you have a premium plan in which Lighthouse runs occur throughout the day or if you've manually triggered any, the ones ran via Vercel can be easily identified by these markers (screenshot below).
  • Number of Lighthouse audits ran per day are limited by account plan "triggered Lighthouse runs per day".

The above screenshots illustrate what Foo's Vercel integration provides. The deployment markers are clearly identified on the charts which show a timeline of all Lighthouse runs per page via Foo (figure 1). Hover over the marker to see the annotation (figure 2). We populate the associated GitHub commit message if applicable (ex: "feat: all the things"). Stay tuned for commit messages from other Git hosts. Click on the marker to see details of the Lighthouse run (figure 3) and access the full report (figure 4).
