Assessment
Steel provides a self-hostable browser API for agent computer use alongside a hosted option. Check the current license before deployment. Browser sandboxing is the product scope; coding harness functions require another layer.

- Agent-oriented evaluation alongside human QA grids.
- Alternative to fully proprietary browser clouds.
Limitations
- Browser operations remain your responsibility.
