Browserbase vs Island (2026)
Both provide browsers for agents and they answer opposite questions, at 12 and 11 of 14.
Browserbase is developer infrastructure: hosted browsers, the Stagehand software development kit and MCP integration, from twenty dollars a month. Island is the enterprise browser as an agent control plane, with per agent permissions, human approval gates, real time data loss prevention on MCP data flows, per invocation audit logs to your security systems and model agnostic provider choice. Browserbase answers how agents browse; Island answers whether your security team will allow it.
Choose Browserbase if
- Documented coverage is slightly broader and you need browser infrastructure to build on.
- Twenty dollars a month with a free tier is the adoption path.
- Your agents run in your own infrastructure and governance is handled elsewhere.
Choose Island if
- Per agent permissions and approval gates are what your security review will require.
- Data loss prevention on MCP flows and per invocation audit logs are hard requirements.
- The enterprise browser is already your endpoint strategy.
