What is Browserbase?
Browserbase is a cloud browser platform that enables AI agents and applications to autonomously read, write, and perform tasks on the web. It provides scalable, fast, and secure browser instances allowing developers to automate workflows and build browser tools for AI without having to manage their own infrastructure. Agent Analytics can track when it visits your website.

Expected Behavior
Browserbase is generic automation, so its pattern is whatever script or AI is driving it. Human guided runs look like short deliberate sessions, while autonomous runs look like a browser that never gets tired. Judge it by request timing and paths, which reveal more than its name does.

Disallow: /Frequently Asked Questions
Should I Block Browserbase?
Judge it by its behavior. Agents in this category range from harmless testing tools to abusive automation, and Browserbase's purpose depends on whoever is running it. Block it if it hits login pages, submits forms, or crawls faster than any human could. Almost none of the top websites we track have robots.txt rules for Browserbase right now.
Does Browserbase Respect Robots.txt?
No. Browserbase is not expected to honor robots.txt, so a disallow rule only states your preference. Enforce the block with firewall or server rules, then confirm in Agent Analytics that its requests actually stop.
Does Browserbase Access Private Content?
It accesses whatever it is scripted to access. If someone gives Browserbase credentials, it can do anything that account can do. Without them, it is limited to public pages.
Why Is Browserbase Visiting My Website?
Someone automated a task that involves your site. Browserbase could be running tests, collecting data, or following an AI system's instructions, and its visit pattern tells you more than its user agent string does.
How Can I Tell if Browserbase Is Visiting My Website?
Agent Analytics tracks Browserbase visits and every other known AI agent, crawler, and scraper alongside it, then authenticates each visit against Browserbase's published verification method. You can also check your server logs for requests whose user agent string contains "Browserbase". Look for regular timing and repeated paths that no human browsing would produce. A log match is still not proof, because any bot can claim to be Browserbase.
