How do I add Chromatic to my allowlist if my resources are behind a firewall?
If your CI environment restricts outbound connections, allow these hosts:
| Host | Protocol |
|---|---|
index.chromatic.com | HTTPS |
notify.chromatic.com | WSS |
chromatic-builds.s3.us-west-2.amazonaws.com | HTTPS |
A *.chromatic.com rule covers the first two hosts. It does not cover the S3 hostname, so add that host separately.
Chromatic uses port 443 for these connections.
If your Git provider restricts incoming connections from Chromatic, configure Git provider IP allowlisting.
