Next.js Maintainer is an internal extension for authorized Vercel maintainers. Its single purpose is to show existing Maintainer signals on supported GitHub issue pages.
The extension:
- reads the current page URL only while it is on
github.com/vercel/next.js; - extracts the public issue number only when the URL exactly matches a Next.js issue;
- sends only that issue number over HTTPS to
https://next-maintainer-agent.vercel.tools/api/chrome-extension/issues/<issue-number>; and - displays the returned canary, reproduction, and priority signal text on that issue page.
The browser attaches the maintainer's existing Vercel Authentication session to that request. This
is authentication information under the Chrome Web Store's definitions. The extension does not
request Chrome's cookies permission, read cookie values, or store authentication credentials.
The private service resolves the authenticated maintainer's Vercel username or account subject
identifier from that session to scope its assessment lookup. The extension does not display or
store that identifier locally.
The extension does not read issue titles, descriptions, comments, form contents, or general browsing history. It does not store extension data, perform analytics, serve advertising, or sell data.
The issue number and authenticated request are used only to provide the extension's maintainer-signal feature. The request is processed by the private Maintainer service and its Vercel authentication and hosting infrastructure. Standard service logs may contain request metadata under Vercel's internal security and retention controls. The extension itself creates no analytics or user profile and does not transfer data to advertisers, data brokers, or other third parties.
The use of information received by this extension complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.
Privacy questions can be directed to the support contact on the extension's Chrome Web Store listing.
