Managing Comments on Preview Deployments

You can resolve comments by selecting the ☐ Resolve checkbox that appears under each thread or comment. You can access this checkbox by selecting a comment wherever it appears on the page, or by selecting the thread associated with the comment in the Inbox.

Participants in a thread will receive a notification when that thread is resolved.

By default, the activity within a comment thread triggers a notification for all participants in the thread. PR owners will also receive notifications for all newly-created comment threads.

Activities that trigger a notification include:

• Someone creating a comment thread
• Someone replying in a comment thread you have enabled notifications for or participated in
• Someone resolving a comment thread you're receiving notifications for

Whenever there's new activity within a comment thread, you'll receive a new notification. Notifications can be sent to:

• Your Vercel Dashboard
• Email
• Slack

To customize notifications for a deployment:

1. Visit the deployment
2. Log into the Vercel toolbar
3. Select the Menu button (☰)
4. Select Preferences (⚙)
5. In the dropdown beside Notifications, select:
   • Never: To disable notifications
   • All: To enable notifications
   • Replies and Mentions: To enable only some notifications

You can manage notifications for threads in the Inbox:

1. Select the three dots (ellipses) near the top of the first comment in a thread
2. Select Unfollow to mute the thread, or Follow to subscribe to the thread

While logged into Vercel, select the notification bell icon and open Comments in the sidebar to see new Comments notifications. To view specific comments, you can:

• Filter based on:
  • Author
  • Status
  • Project
  • Page
  • Branch
• Search: Search for comments containing specific text

You can also resolve comments from your notifications.

To reply to a comment, or view the deployment it was made on, select it and select the link to the deployment.

Email notifications will be sent to the email address associated with your Vercel account. Multiple notifications within a short period will be batched into a single email.

When you configure Vercel's Slack integration, comment threads on linked branches will create Slack threads. New activity on Slack or in the comment thread will be reflected on both platforms. See our Slack integration docs to learn more.

Sometimes, issues appear on a webpage for certain browsers and devices, but not for others. It's also possible for users to leave comments on a preview while viewing an outdated deployment.

To get around this issue, you can select the screen icon beside a commenter's name to copy their session info to your clipboard. Doing so will yield a JSON object similar to the following:

{
  "browserInfo": {
    "ua": "Mozilla/5.0 (Macintosh; Intel Mac OS X 9_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/106.0.0.0 Safari/537.36",

On desktop, you can hover your cursor over a comment's timestamp to view less detailed session information at a glance, including:

• Browser name and version
• Window dimensions in pixels
• Device pixel ratio
• Which deployment they were viewing
