Kong AI Gateway
AI plugins on a mature API gateway platform
Company overview
Kong AI Gateway extends Kong Gateway with AI-specific plugins covering prompt guards, response handling, PII sanitisation, semantic caching, routing and rate limiting, deployable wherever Kong runs.
Ideal customer: API platform and infrastructure teams with an existing Kong or Kubernetes footprint
- Applying prompt and response guards as gateway plugins
- Semantic caching and rate limiting for LLM traffic
- Routing across multiple model providers from one proxy
GateYourAI verdict
Kong's advantage is that AI controls are plugins on a data plane many organisations already operate, with self-hosted and Kubernetes deployment as first-class options. Per-plugin verification against Kong's developer documentation is queued before we mark individual controls as available.
Best for: Platform teams already running Kong that want AI policy in the same data plane. Read how we assess platforms.
Security capabilities
A capability is marked available only when an official page or documentation says so. “Not publicly documented” means we could not find it — not that the vendor lacks it.

Cost-optimization capabilities
Token reduction, avoided calls, cheaper-model routing, budgets and reporting are tracked separately because they are not interchangeable.

Strengths
- Runs in the same data plane as existing API traffic
- Self-hosted and Kubernetes deployment are core to the platform
Limitations
- AI capabilities are spread across plugins that must be configured individually
- Some capabilities are enterprise-tier only and need contract-level confirmation
