Learn how Comments integrates with Git providers like GitHub, GitLab, and BitBucket, as well as Vercel's Slack app.

Table of Contents

Comments are available for projects using any Git provider. Github, BitBucket and GitLab are supported automatically with the same level of integration.

Pull requests (PRs) with deployments enabled receive generated PR messages from Vercel bot. These PR messages contain the deployment URL.

The generated PR message will also display an Add your feedback URL, which lets people visit the deployment and automatically log in. The PR message tracks how many comments have been resolved.

Vercel will also add a check to PRs with comments enabled. This check reminds the author of any unresolved comments, and is not required by default.

To make this check required, check the docs for your favorite Git provider. Docs on required checks for the most popular git providers are listed below.

Commenting is available for deployments made with the Vercel CLI. The following git providers are supported for comments with Vercel CLI deployments:

  • GitHub
  • GitLab
  • BitBucket

See the section on Git provider integration information to learn more.

Commenting is available in production and localhost when you use the Vercel Toolbar package.

The Vercel Slack app connects Vercel deployments to Slack channels. Any new activity will create corresponding Slack threads, which are synced between the deployment and Slack so that the entire discussion can be viewed and responded to on either platform.

To get started:

  1. Go to our Vercel Slack app in the Vercel Integrations Marketplace
  2. Select the Add Integration button from within the Marketplace, then select which Vercel account and project the integration should be scoped to
  3. Confirm the installation by selecting the Add Integration button
  4. From the pop-up screen, you'll be prompted to provide permission to access your Slack workspace. Select the Allow button
  5. In the new pop-up screen, select the Connect your Vercel account to Slack button. When successful, the button will change to text that says, "Your Vercel account is connected to Slack"

Private Slack channels will not appear in the dropdown list when setting up the Slack integration unless you have already invited the Vercel app to the channel. Do so by sending /invite @Vercel as a message to the channel.

  1. In any channel on your Team's Slack instance enter /vercel login
  2. Select Continue with Vercel to open a new browser window
  3. From the new browser window, select Authorize Vercel to Slack
  4. Once the connection is successful, you'll receive a "Successfully authenticated" message in the Slack channel.
  5. You can use /vercel whoami at any time to check that you're successfully linked

Linking Slack and Vercel does the following:

  • Allows Vercel to translate @ mentions across messages/platforms
  • Allows you to take extra actions
  • Allows user replies to be correctly attributed to their Vercel user instead of a slack-{slackusername} user when replying in a thread

If you configured the Slack app before October 4th, 2023, the updated app requires new permissions. You must reconfigure the app to subscribe to new comment threads and link new channels.

To do so:

  1. Visit your team's dashboard and select the Integrations tab
  2. Select Manage next to Slack in your list of integrations. On the next page, select Configure
  3. Configure your Slack app and re-authorize it

Your previous linked channels and subscriptions will continue to work even if you don't reconfigure the app in Slack.

To see a specific project's comments in a Slack channel, send the following command as a message to the channel:

/vercel subscribe

This will open a modal that allows you to configure the subscription, including:

  • Subscribing to comments for specific branches
  • Subscribing to comments on specific pages

You can specify pages using a glob pattern, and branches with regex, to match multiple options.

You can also configure your subscription with options when using the /vercel subscribe command. You can use the /vercel help command to see all available options.

When a new comment is created on a PR, the Vercel Slack app will create a matching thread in each of the subscribed Slack channels. The first post will include:

  • A link to the newly-created comment thread
  • A preview of the text of the first comment in the thread
  • A ✅ Resolve button near the bottom of the Slack post
    • You may resolve comment threads without viewing them
    • You may reopen resolved threads at any time

Replies and edits in either Slack or the original comment thread will be reflected on both platforms.

Your custom Slack emojis will also be available on linked deployments. Search for them by typing :, then inputting the name of the emoji.

Use the following Slack command to list all available options for your Vercel Slack integration:

/vercel help

To receive comment notifications as DMs from Vercel's Slack app, you must link your Vercel account in Slack by entering the following command in any Slack channel, thread or DM:

/vercel login

/vercel helpList all commands and options
/vercel subscribeSubscribe using the UI interface
/vercel subscribe team/projectSubscribe the current Slack channel to a project
/vercel subscribe listList all projects the current Slack channel is subscribed to
/vercel unsubscribe team/projectUnsubscribe the current Slack channel from a project
/vercel whoamiCheck which account you're logged into the Vercel Slack app with
/vercel logoutLog out of your Vercel account
/vercel login (or link or signin)Log into your Vercel account

Adding Comments to your issue tracker is available on all plans

Any member of your team can covert comments to an issue in Linear, Jira, or GitHub. This is useful for tracking bugs, feature requests, and other issues that arise during development. To get started:

  1. The following issue trackers are supported:

    Once you open the integration, select the Add Integration button to install it. Select which Vercel team and project(s) the integration should be scoped to and follow the prompts to finish installing the integration.

    On Jira, issues will be marked as reported by the user who converted the thread and marked as created by the user who set up the integration. You may want to consider using a dedicated account to connect the integration.

  2. On the top-right hand corner of a comment thread, select the icon for your issue tracker. A Convert to Issue dialog will appear.

    If you have more than one issue tracker installed, the most recently used issue tracker will appear on a comment. To select a different one, select the ellipsis icon (⋯) and select the issue tracker you want to use:

    The context menu showing issue tracker options.
    The context menu showing issue tracker options.
  3. Fill out the relevant information for the issue. The issue description will be populated with the comment text and any images in the comment thread. You can add additional text to the description if needed.

    The fields you will see are dependant on the issue tracker you use and the scope it has. When you are done, select Create Issue.


    Users can set the team, project, and issue title. Only publicly available teams can be selected as Private Linear teams are not supported at this time.


    Users can set the project, issue type, and issue title.

    You can't currently convert a comment into a child issue. After converting a comment into an issue, you may assign it a parent issue in Jira.


    Users can set the repository and issue title. If you installed the integration to a Github Organization, there will be an optional field to select the project to add your issue to.

  4. Vercel will display a confirmation toast at the bottom-right corner of the page. You can click the toast to open the relevant issue in a new browser tab. The converted issue contains all previous discussion and images, and a link back to the comment thread.

    When you create an issue from a comment thread, Vercel will resolve the thread. The thread cannot be unresolved so we recommend only converting a thread to an issue once the relevant discussion is done.


    If the email on your Linear account matches the Vercel account and you follow a thread converted to an issue, you will be added as a subscriber on the converted Linear issue.


    On Jira, issues will be marked as reported by the user who converted the thread and marked as created by the user who set up the integration. You may wish to consider using a dedicated account to connect the integration.


    The issue will be marked as created by the vercel-toolbar bot and will have a label generated based on the Vercel project it was converted from. For example Vercel: acme/website.

    If selected, the converted issue will be added to the project or board you selected when creating the issue.
