OG images for Substack & Beehiiv newsletters, generated automatically
Substack and Beehiiv don’t allow head code, but they let you upload a social image per post — generate it with OGKit in seconds. Each page gets a crisp 1200×630 preview image the moment someone shares it — no design work, no image uploads.
1. Copy this snippet
2. Where to paste it in Substack & Beehiiv newsletters
Open the URL above with your title, save the PNG, and upload it in Post settings → Social preview image. Use the playground to tweak the template.
3. Check the result
Paste any page URL into the free link preview checker to see exactly how it will look on X, LinkedIn, Slack and Facebook. Social networks cache previews, so re-share or use their debuggers after changing tags.
Why use OGKit with Substack & Beehiiv newsletters?
- Posts with a large image card get noticeably more clicks than bare links — and most Substack & Beehiiv newsletters sites ship without one.
- Images are rendered once at the edge and cached, so they load in milliseconds for crawlers.
- 6 designer templates (blog, product, docs, minimal, gradient, photo) and your brand color.
- Free forever with a small “made with OGKit” badge; paid plans remove it.
Parameters
template, title, desc, site, accent (hex), image (for product/photo), tag, author, date. Or use /auto?url= to read the title from the page itself. Full reference in the docs.
