Agentic Index
Dome Systems vs Prefactor (2026)
Both govern a portfolio of agents from outside the runtimes, at 8 and 6 of 14.
Dome registers agents, filters tools through an MCP Gateway, enforces per action Cedar policy before execution and audits every governed action across any cloud, in early access. Prefactor is framework agnostic, governing an agent portfolio with identity, quality gates, cost attribution and lifecycle governance. Dome enforces harder with a formal policy language; Prefactor answers the question nobody else does, which is what each agent costs you.
Choose Dome Systems if
- Documented coverage is broader and Cedar as a formal policy language is worth having.
- Enforcement before execution, not detection after, is the control you require.
- MCP Gateway tool filtering matches the architecture you are building.
Choose Prefactor if
- Cost attribution per agent is the number nobody can currently produce for you.
- Quality gates in the lifecycle stop bad agents reaching production.
- Portfolio governance across many agents is the problem, not individual enforcement.
