Developer Simon Hartcher created og-check, a CLI tool that allows testing OpenGraph tags on localhost before deployment. The tool fetches meta tags and renders previews directly in the terminal using the Kitty graphics protocol, supporting several popular terminals. This eliminates the need for public URLs and avoids caching issues with external validators.
Background
OpenGraph tags are meta tags that control how content appears when shared on social media platforms like Facebook, Twitter, and LinkedIn. Developers typically need to use external tools that require public URLs to test these previews.
