What NovaAct does

Amazon Nova Act, which developers use to build agents that carry out tasks in a web browser.

As an autonomous agent, it uses a website like a person would, clicking, typing and filling in forms to finish a task for someone. The kinds of AI agent that visit websites.

Should you allow it?

Make your journeys work for it. Many browser agents look like an ordinary browser, so you can't reliably block them by name; test whether they can finish your key tasks instead. A decision guide for blocking or allowing AI crawlers.

How to allow or block NovaAct

NovaAct reads the NovaAct group in your robots.txt. To block it everywhere:

User-agent: NovaAct
Disallow: /

To allow it everywhere, even if another rule blocks other bots:

User-agent: NovaAct
Allow: /

Robots.txt is a request, not a lock: well-behaved crawlers follow it, impostors don't. Robots.txt for AI agents.

How to tell if it's really NovaAct

Our registry doesn't verify NovaAct against published IP ranges yet, so treat a request that uses the name as a claim, not proof: anyone can send its user agent. Check Amazon's documentation for how to verify it.

Every Amazon agent, and a robots.txt for all of them →

Does NovaAct visit your site? Ghost Agent Lab reads your CDN or server logs and shows every request from NovaAct and 1,566+ other known agents: what they read, what your site sent back, and whether each request was genuine. See agent traffic, or check whether AI agents can use your site for free.
