Use case
Social preview images that update themselves.
Stop manually exporting a new image every time a blog post or product page changes. Point your og:image tag at a hosted Templates On URL and it always reflects the current title, price, or content — no rebuild, no re-upload.
How it works
- 1Design a template that mirrors your share-card layout — title, subtitle, maybe a product photo.
- 2Set your page's og:image meta tag to the hosted render URL with the relevant params (e.g. ?title=...).
- 3Every time the underlying content changes, the image changes with it automatically — no extra deploy step.
Before & after
Every new blog post needs a manually designed share image.
One template, driven by the post title and metadata via URL params — no design tool round-trip per post.
A product price or title changes but the old share image is stuck in the crawler cache of a stale export.
The hosted URL always renders current params, so the image is never out of date.
Adding social images to a static site means a build step and a folder of exported PNGs.
GET /api/og/:id serves the PNG on request — no export step, no asset folder to manage.
Trying it out means signing up and configuring something first.
OG image hosting has no plan gate — free preview rendering works before you even create an account.
Who it's for
Blogs & content sites
Every post gets a correct share card automatically, keyed off its own title and metadata.
E-commerce & marketplaces
Product pages share with an accurate, current price and image — no stale exported PNGs.
SaaS marketing sites
Landing pages and docs get on-brand social previews without a designer touching every page.
Frequently asked
How do I use this on my site?
Point your page's <meta property="og:image"> tag at the hosted render URL for your template, passing the relevant values as query params (e.g. ?title=...). The endpoint serves a fresh PNG on every request.
Does the image update automatically when my content changes?
Yes — since the URL renders live from the params you pass, there's no export or re-upload step. Change the params (or what your page passes in), and the image changes.
Is this free to use?
OG image hosting has no plan gate, and previewing a template while designing it never spends any usage allowance.
Can I use a product photo or logo, not just text?
Yes — a template can include image fields alongside text, so a share card can carry a product photo or logo the same way it carries a title.
Dynamic og:image URL for blog posts and product pages
Point your og:image meta tag at a hosted render URL with params (?title=…) and the preview image always reflects the current title, price, or content — no rebuild, no re-uploaded PNGs. OG hosting has no plan gate, so it works before you even create an account.
