MetaPreview
SNS Share Preview Inspector
See exactly how your page looks when shared on Twitter/X, Facebook, LinkedIn, and Slack. Audit OG tags and get instant warnings for missing or problematic meta tags.
// overview
MetaPreview lets you instantly preview how any webpage will look when shared on social media. Click the extension icon to see live preview cards for Twitter/X (supporting both summary and summary_large_image formats), Facebook (Open Graph 1.91:1 format), LinkedIn, and Slack unfurl format — all rendered from the page's actual meta tags. The Issues tab automatically audits your Open Graph tags: missing og:image, images that are too small or have wrong aspect ratios, titles that are too short or long, missing descriptions, and absent twitter:card tags. The Raw Tags tab displays every detected meta value for complete debugging visibility. Completely free.
