Comments are available on all plans
Comments allow Teams and invited participants to give direct feedback on Preview Deployments. Comments can be added to any part of the UI, opening discussion threads that can be linked to Slack threads. This feature is enabled by default on all preview deployments, for all account plans, free of charge. The only requirement is that all users must have a Vercel account.
