CMS Assets places your edge proxy between your site and CMS provider. Without changing your content workflow, asset URLs are served through your own domain to reduce costs, improve control, and keep performance stable.
1. Connect Your CMS
Add a tenant, choose Prismic or Contentful, and provide repository/space settings.
2. Enable the Proxy
Every tenant gets a dedicated `*.cmsassets.com` domain for serving asset files.
3. Track Savings
Bandwidth is routed through your edge and reduces CMS overage costs.

- Environment variable auto-detection
Install
Add the package once and use the same helper for every supported CMS.
CMS Assets is for teams using a headless CMS (Prismic, Contentful, Sanity, etc.) who want faster asset delivery, predictable caching, and tighter control over bandwidth costs — especially when running multiple sites or tenants.
What problem does CMS Assets solve?
+
It adds a controllable edge layer in front of your CMS media. Assets are cached globally, origin requests drop dramatically, and you can prevent unexpected CDN overages by tracking and limiting usage per tenant.
How do we integrate it into an existing site?
+
Typically it’s a minimal change: route media URLs through your tenant domain (e.g. tenant.cmsassets.com) using our SDK or a small URL rewrite step in your CMS client. No infrastructure rebuild required.
Does it work with multiple sites or brands?
+
Yes. CMS Assets is multi-tenant by design. Each tenant has its own domain, origin config, cache behavior, and usage tracking — ideal for agencies and teams managing multiple properties.
Will this break image transformations or query params?
+
No. Query parameters are forwarded 1:1 to the origin (for Imgix-style transforms, format, width, etc.). You can also choose whether query strings affect caching per file type.
What about video and large files?
+
Videos and large assets are supported, including Range requests for streaming. CMS Assets can cache full responses and safely handle partial content requests when needed.
