FAQ

Frequently Asked Questions

An Open Graph image (og:image) is the preview image shown when you share a link on Twitter, LinkedIn, Slack, or Discord. Dynamic OG images change per page — showing the actual title, description, and branding of each page rather than a static fallback.

Send a POST request with your title, description, and template choice. We render a 1200×630px image and return a URL. Drop that URL into your og:image meta tag. That's it.

Yes — completely free, unlimited image generation. No credit card required, no hidden limits.

Bannerbear starts at $49/mo. Imago API is completely free — no monthly fee. Both generate dynamic images via API. Imago is purpose-built for OG images and social cards with a simpler setup.

Any framework that can make an HTTP request — Next.js, Nuxt, SvelteKit, plain HTML, Python, PHP, Ruby, etc. See the docs for framework-specific examples.
