MongoDB Realm Hosting allows you to host, manage, and serve your application's static media and document files. You can use Hosting to store individual pieces of content or to upload and serve your entire client application.

To get started, enable hosting for your application then start uploading content.

A file is static if you can serve it directly to clients without requiring additional processing or logic to generate it. Static content includes document files, such as HTML, JavaScript, and CSS, as well as media files like images, audio, and videos.

MongoDB Realm hosts your application's content behind a unique domain name. By default, MongoDB Realm uses domains of the following form:

<Your App ID>

You can configure MongoDB Realm to host content at a custom domain name that you own in addition to the default hosting domain.

A resource path is a string that uniquely identifies an uploaded file based on its position in the file tree. You can access a hosted file through a unique URL that consists of your application's hosting domain followed by the file's resource path.

For example, a PNG image of a company's logo hosted in a directory named images would have the resource path /images/logo.png. You could access this image at a URL similar to the following:

MongoDB Realm enforces constraints on static hosting across several dimensions for each Realm app. The following constraints apply to all static content hosted by MongoDB Realm:

Maximum File Size
25 megabytes
Maximum Total Storage
1 gigabyte
Maximum Total Files
20,000 files
Maximum CDN Flushes
25 flushes per hour
Maximum Bandwidth
100 gigabytes
