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, and produces portable, regulator-ready evidence — while keeping your existing routing.
Multi-provider routing & failover
Yes
Yes — client-defined, versioned, auditable

Identity-aware policy enforcement (per prompt/response/tool call)
Limited
Yes
Agent identity bound to a verified human
No
Yes — AIDA delegated-authority credentials
Immutable audit trail / portable evidence
Partial (logs)
Yes — follows traffic across failover
Regulatory exam packages (SR 11-7, FINRA 3110, FFIEC, EU AI Act)
No

MCP tool-call governance
No
Yes
On-premises / air-gap deployment
Varies
Yes — no data transits APERION
Categories reflect what each layer is built for. Gateways are strong at routing and cost visibility; Smartflow is built to govern. See the individual comparisons for sourced, product-specific detail.
