Buyer questions

What is Nikkel?

Nikkel is a visual annotation and QA tool for designers, developers, and their clients. You can pin comments directly on live or staging websites, inspect element styles without opening DevTools, and every comment automatically captures a screenshot and CSS details. Clients can reply from a shared link with no account or extension needed.

Do my clients need an account?

No account is needed for clients. You can share a generated link and they can leave feedback directly on the live site without signing up, acting as guest reviewers.

Does it work on pages which require a login?

Yes, Nikkel's extension runs in your own browser session, so it works on any page you're logged into, including staging environments and password-protected previews. Your reviewer needs the extension installed for this to work.

What can I do with Nikkel's MCP connector?

Nikkel's MCP connector lets you hook Claude, Cursor, or another AI coding assistant directly into your projects so it can pull your annotated feedback and screenshots and act on fixes without manual ticket-writing.

How does it work?

Install the extension and open any webpage to start reviewing. Switch between Browse and Annotate modes to drop pins directly on page elements, share a single link with teammates or clients to collaborate in context, and manage every project from your dashboard.
