Vercel Toolbar
The Vercel toolbar is an overlay that appears on your deployed site, giving your team a set of collaboration and testing tools without leaving the browser. To open it, click the arrow next to the Visit button in the dashboard and select Visit with Toolbar.
Feature flags
The toolbar integrates with Vercel's native feature flag provider. If you have feature flags configured, you can override them directly from the toolbar.
Click the toolbar, search for Flags, and open the Flags Explorer. From there, override any flag and apply the change. The override is local to your session, so you can test a feature without affecting anyone else.
Draft mode
For content-driven sites with a CMS, draft mode lets you preview unpublished content. Click the toolbar, search for Draft Mode, and toggle it on. You'll see draft posts and content that regular visitors can't access.
This is especially useful for editorial workflows where writers and editors need to review content before it goes live.
Comments
Click Comment in the toolbar to pin comments anywhere on the page. Your colleagues with the toolbar activated can see and reply to them.
If you add comments on a preview deployment, they'll show up directly in the associated GitHub pull request, keeping the conversation connected to the code change.
Recap
- Feature flags can be overridden locally from the toolbar for testing
- Draft mode previews unpublished CMS content without affecting the live site
- Comments pin feedback directly on the page and sync with GitHub PRs on preview deployments
