Browserbase
Browserbase removes the operational work of running headless Chrome at scale - proxies, fingerprinting, CAPTCHA, session storage - which is exactly the layer most agent-building teams don't want to own themselves. It's infrastructure, not a finished agent, so there's still integration work to do on top of it.
Pros
- Automatic CAPTCHA solving and proxy/fingerprint handling out of the box
- Free tier available to test before paying
- Session replay and observability for debugging agent runs
- Open-source Stagehand framework for the automation layer
Cons
- Free tier is capped at just 1 browser hour, not enough for real workloads
- Requires developer effort to wire into an actual agent - it's infrastructure, not an end-user tool
- Overage billing on browser-hours can add up for high-volume use
