Add Explo Domains to your Content Security Policy
https://*.explo.co
to your CSP to ensure our embed can work properly and make the proper requests. If you’re not sure if you have a strict CSP, then you likely don’t. If you prefer not to wildcard Explo’s subdomains, these are the necessary domains:
default
one.
custom-assets.explo.co
is used for custom fonts, so please ensure to allowlist this domain if you are using custom fonts. This asset used to be served at https://explo-custom-fonts.s3.us-west-1.amazonaws.com
, but we have since migrated it to custom-assets.explo.co
(in January 2025). We will continue to support both for backwards compatibility. Our support team will reach out to those who might be using the old URL in their allowlist.
