We don’t implement IP blocking on our end, so there’s no need to whitelist any specific IP addresses. Builder.io functions based on the IP address it detects. Our services are distributed across multiple hosting platforms that utilize various global edge nodes. For example, our JavaScript content is delivered via the CloudFront CDN, which doesn’t guarantee specific IP addresses or ranges. Similarly, our HTML content is served through Fastly.
Since our CDN uses Amazon CloudFront, you can utilize the same IP range (seethe below links). If, for some reason, you also require our origin server IP range, you can refer to Google Cloud Platform, though this shouldn’t be necessary. Lastly, you may find it useful to whitelist or add these Builder.io domains to your content security policy:
- *.builder.io
- *.builder.live
- *.builder.codes
- firestore.googleapis.com
