AFIT verdict
Browserbase is a strong choice for developers building and scaling AI browser agents that need to bypass CAPTCHAs, handle complex authentication, and run concurrent browser sessions. The catch is that it is a commercial cloud platform, though they open-source some client tools like Stagehand and the Browse CLI.
