Answers about FastOG's dynamic Open Graph image API, pricing, and caching.
An Open Graph image API generates the 1200×630 social preview image for a page on demand from a URL. FastOG renders a unique, branded card for every blog post, product page, or SaaS page automatically — no design work, no uploads. It works with any framework through one-file signers for Node, React, SvelteKit, Vue, Astro, PHP, Python, and more.
Yes. There's a free OG Image Tester that needs no login. Want a static one-off cover? Buy Studio credits and download it. Need dynamic per-link images? That's a Dynamic API plan. Identical URLs are edge-cached so re-shares cost nothing.
Studio: one credit per downloaded PNG (buy a pack, credits never expire). Dynamic API: an active monthly subscription with unmetered current-plan renders — and identical URLs are edge-cached, so re-shares cost nothing.
No. FastOG signs the content, not the clock — a URL stays valid until you rotate your API key's HMAC secret. Content-signing also keeps caching deterministic: identical parameters always produce the identical, cached URL.
Yes — FastOG is framework-agnostic. It works with plain HTML, WordPress, Astro, Nuxt, SvelteKit, PHP, Python, Ruby, and any server-side language. Just drop in your language's signer file from the SDK page.
