How to validate Open Graph images
Social networks cache og:image aggressively. The typical workflow is: build your OGKit image URL, preview it in the Playground to confirm the card layout, then paste your page URL into opengraph.xyz or the Facebook Sharing Debugger to see exactly what Slack, iMessage, Twitter, LinkedIn, and Facebook will display after scraping.
After a redesign or content update, use the Facebook Sharing Debugger to force-refresh the cached og:image for a specific URL. Twitter and X require their own Card Validator for the same purpose. LinkedIn has a Post Inspector that does the same. The OGKit API returns deterministic URLs, so CDNs and scrapers automatically serve the cached byte-identical PNG on every subsequent unfurl — no re-render cost, no rate-limit surprise.
For a deeper walkthrough of metadata best practices, Next.js openGraph.images integration, and common og:image mistakes, read the Open Graph images SEO guide.
