Simple routing vs full-stack AI governance.
Bifrost is a fast AI gateway with model routing, failover, and an MCP gateway. DVARA is a governance-first platform — covering policy enforcement, argument-level MCP governance, compliance evidence generation, and enterprise security depth that a performance-first gateway does not match.

DVARA is commercial software — by design, not as a limitation. You get a vendor, an SLA, signed audit, and a support contract; you don’t get a free fork. For teams who need that trade, DVARA is the answer; for teams happy to maintain their own fork, the OSS option may be a better fit. Bifrost is a solid choice for teams that need fast model routing, failover, and a performant MCP gateway. DVARA is for organisations that need deep governance, compliance, argument-level MCP control, and enterprise security on top of routing.
