What is an OG image API?

An OG (Open Graph) image API generates social preview images dynamically via HTTP requests. Instead of manually designing images in Figma or Photoshop for each page, you pass parameters like title, template, and brand color to an API endpoint, and it returns a PNG image optimized for social media sharing on Twitter, Facebook, LinkedIn, and Slack.

How much does OGPeek cost?

OGPeek offers a free tier with 50 images/day (watermarked), a Starter plan at $9/month for 10,000 images with no watermark, and a Pro plan at $29/month for 50,000 images with custom fonts. No credit card required for the free tier.

How is OGPeek different from Vercel OG or Bannerbear?

OGPeek is a hosted API — no setup, no infrastructure, no code to maintain. Vercel OG requires self-hosting on Vercel and writing your own rendering code. Bannerbear starts at $49/month with a visual template editor. OGPeek starts at $9/month with pre-built templates and a simple GET/POST API that works with any stack.

Can I use OGPeek with any framework?

Yes. OGPeek is a standard REST API that returns PNG images. It works with Next.js, Gatsby, Hugo, Jekyll, WordPress, Django, Rails, Express — any framework that can set meta tags. Just point your og:image meta tag to the OGPeek URL with your parameters.

Do OGPeek images work on Twitter, Facebook, and LinkedIn?

Yes. OGPeek generates 1200x630 PNG images, which is the standard size supported by Twitter (X), Facebook, LinkedIn, Slack, Discord, and iMessage link previews. All templates are optimized for readability at this size.
