COMPARISONS
AI gateways like LiteLLM, Portkey, TrueFoundry, and Cloudflare AI Gateway solve routing, failover, and cost visibility for platform teams. Smartflow is a runtime governance control plane: it does that routing and caching, and adds identity-bound policy enforcement on every prompt, response, and tool call — plus regulator-ready evidence, deployed on-premises. Many enterprises run both. This page shows where each fits.
Part of the APERION Trust Fabric.
A gateway is a platform-team purchase for routing, failover, and observability. A governance control plane is a CISO and compliance purchase for identity, enforcement, and evidence. Most vendors conflate the two. Smartflow separates them cleanly — and covers both.
Where a gateway fits: routing across providers, cost and latency visibility, a single API. If that is the whole requirement, a gateway is enough.
Where Smartflow adds the layer: verifies the human, binds the agent to that human, governs every call against policy, sends the agent back to its human when it exceeds its authority, and produces portable, regulator-ready evidence, while keeping your existing routing.
