Store audiobooks on Cloudflare R2

Why R2 suits audiobooks

Audiobooks are large and listened to many times. With R2, phones download from storage without traffic fees, and a small home server or VPS only answers short API requests.

Connect R2 with the wizard

Berth checks the token, creates the bucket (an existing one is fine), sets CORS for your server addresses, derives the S3 keys from the token and runs the connection check. Then make R2 the default storage so new books go there.

1. In the Cloudflare dashboard create an API token with the “Workers R2 Storage: Edit” permission (Profile → API Tokens).
2. Copy the Account ID from the R2 page of the dashboard: 32 hexadecimal characters.
3. In the Berth admin open the storage settings and choose “Cloudflare R2”.
4. Paste the Account ID and the token, keep the bucket name berth or enter your own, and press “Connect”.

The bucket name must be 3–63 characters: lowercase letters, digits and hyphens, not starting or ending with a hyphen.

Optional: a custom domain or CDN

The wizard sets up direct signed links, which is enough for most families. If you attach a custom domain to the bucket in Cloudflare, you can switch the storage to “Through a CDN” and enter that domain as the CDN address. Note that unsigned CDN links do not expire.
