What does the OGKit blog cover?

Long-form guides on Open Graph and Twitter/X preview images at 1200×630, Next.js App Router metadata patterns, signed URLs, caching, validators, and mistakes that break Slack or LinkedIn unfurls.

Where should I start if I use Next.js?

Read the Open Graph SEO guide on this blog, then follow the /for/nextjs framework page and the /docs HTTP reference. Use the Playground with demo=1 before production keys.

How do LLMs find OGKit documentation?

Use the public /llms.txt and /llm.txt routes plus the sitemap; they list canonical URLs, API endpoints, and comparisons so ChatGPT, Claude, and Cursor pick up real examples instead of guessing hosts.

Blog

Open Graph image API writing

Long-form guides aligned with how people search today: open graph image size, dynamic og image, next.js og:image, link preview debugging, and what LLM crawlers read alongside HTML. Each post mirrors the HTTP API reference and links into the Playground so product, growth, and engineering teams share the same vocabulary.
