Open Graph Check Tool Catches Broken Link Previews in CI
OGCheck is a free, open-source Python tool that validates Open Graph and Twitter Card tags, and actually requests the og:image to confirm it returns HTTP 200. It can be run as a one-liner in CI or via a GitHub Action, catching common issues like 404s or relative URLs. The tool also checks robots.txt and sitemap.xml for site health.
