Agentic Index
Asteroid vs Island (2026)
Both put governance around browser agents in serious environments, at 9.5 and 11 of 14. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Island is the enterprise browser as a control plane, building and running governed autonomous agents 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. Asteroid supervises browser and computer use in regulated back offices, where a frontier model drives the portal, the agent then compiles its own deterministic script and can discover the private API underneath, graph based and self healing, HIPAA ready with live human supervision. Island governs everything; Asteroid turns the exploration into something repeatable.
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Asteroid and Island are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 969 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Asteroid if
- Compiling exploration into a deterministic script is the reliability mechanism you want.
- Discovering the private API underneath is a genuinely different and more durable outcome.
- Live human supervision on regulated back office work is your operating model.
Choose Island if
- Documented coverage is broader and the enterprise browser governs everything, not just agents.
- Data loss prevention on MCP flows and per invocation audit logs are security requirements.
- Model agnostic provider choice at the browser layer keeps your options open.
