Deployment protection and preview PR comments

You can lock default hostnames behind SSO-style deployment protection, keep previews out of search with X-Robots-Tag, and get preview URLs posted on pull requests and commits.

Deployment protection

Enable protection so visitors to default preview and project hostnames must authenticate before they see the app. That keeps unfinished work off the public internet while your team still shares links internally.

Configure protection from project security or deployment settings. Production custom domains can stay public while default easel.sh hosts remain gated.

Previews in GitHub

When a deploy finishes, Easel can comment on the pull request and related commits with the preview URL. Reviewers open the exact build without hunting in the dashboard.

Previews also send X-Robots-Tag so crawlers skip indexing. Pair that with protection for private work. See Deployment URLs and Deployments.
