OG Image Generator vs @vercel/og

OG Image Generator and @vercel/og use the same underlying rendering engine (Satori), but take opposite approaches. @vercel/og is a free, open-source library where you build templates yourself. ogimg.xyz is a managed API with ready-made templates — you trade some customization for dramatically faster setup.

Frequently Asked Questions

Do ogimg.xyz and @vercel/og use the same technology?

Yes. Both use Satori by Vercel to convert layouts to SVG, then render to PNG. The difference is that ogimg.xyz provides pre-built templates and a managed API, while @vercel/og requires you to write JSX templates yourself.

Is @vercel/og really free?

The library is free and open source. However, you still need hosting (Vercel's free tier works for small projects). You also invest development time building and maintaining templates — which ogimg.xyz eliminates.

Can I switch from @vercel/og to ogimg.xyz?

Yes. Replace your self-hosted API route with an ogimg.xyz URL in your og:image meta tags. You can migrate one page at a time. The main trade-off is that you'll use ogimg.xyz's templates instead of your custom JSX templates.

Which CSS features does @vercel/og support?

@vercel/og (via Satori) supports a subset of CSS: Flexbox layout, basic typography, colors, borders, and backgrounds. It does NOT support CSS Grid, position: absolute, box-shadow, or many other common CSS properties. ogimg.xyz's templates handle these limitations for you.
