# OGKit

> Open Graph lint for web, extension, and CLI. Markdown versions of these pages are available at the linked `.md` URLs or by sending `Accept: text/markdown`.

OGKit checks Open Graph and social-preview metadata. It is a linter (web scan, browser extension, CLI/CI), not an OG image generator.
