Browsing agent from Browser Use

# Browser Use (library and cloud)

In short

Browser Use (library and cloud) is Browser Use's browsing agent. Browser Use has no robots.txt token, so robots.txt cannot address it and the crawl cannot measure a block rate. The operator publishes nothing a site can check. Browser Use says its cloud created 3.7M sessions in the seven days to 2026-10-14 (vendor figure via Verisoul).

Operator

Purpose

Task agent [All task agent rows](https://agentreadycrawlers.com/crawlers/purpose/task-agent/). A browsing agent that clicks, fills forms and finishes a job for a person.

User-agent string

No exact string is published. What the operator or a third party says: Chromium driven over the DevTools Protocol; Verisoul reports it names itself only in some setups

robots.txt token

None. No robots.txt line can address this agent.

Note. MIT-licensed. Browser Use says its cloud created 3.7M sessions in the seven days to 2026-10-14 (vendor figure via Verisoul). No key directory at browser-use.com (404, 2026-11-04).

## Allow and refuse lines

This agent has no robots.txt token, so there are no lines to copy. Without a token, a published list or a signature, a site owner cannot tell it from an ordinary visitor by request alone.

Refusing or allowing in robots.txt states a preference. For this row the operator or its documentation says robots.txt may not govern the fetch, so enforcement belongs in your WAF.
