Safari localhost proxy limitations

Discover Safari’s localhost proxy limitations in Percy and workarounds for proper resource loading.

Localhost proxy support on Safari

Percy does not support localhost proxying on Safari. If a resource link in your DOM snapshot uses localhost:<port>/resource, it will not load on Safari, even if captured via the SDK. Safari bypasses the proxy for localhost and tries to resolves it directly.

Workarounds

• Use relative paths for resources.
• Use a public DNS entry that resolves to 127.0.0.1 (Example: localtest.me or domaincontrol.com or create one on your own).
• Create a custom domain with a hosts file entry resolving to 127.0.0.1 (Example: add 127.0.0.1 mylocalsite.dev).
