overview

What is Kong AI Gateway?

Kong AI Gateway is a AI-aware gateway tool developed by Kong that enables platform teams and developers to manage, secure, and optimize traffic for Large Language Models (LLMs), Model Context Protocol (MCP), and Agent-to-Agent (A2A) communication. It extends traditional API management capabilities to the evolving landscape of generative AI applications and multi-agent systems, providing a high-performance control plane to secure, govern, and observe AI-native systems and LLM traffic end-to-end.

use cases

Who Should Use Kong AI Gateway?

Kong AI Gateway is primarily designed for organizations and platform teams that require enterprise-grade management, security, and observability for their AI and LLM deployments. It is particularly beneficial for those already leveraging Kong's API management ecosystem.

Platform teams and developers deploying AI/ML applications requiring centralized governance, security, and observability for AI traffic and LLM usage.
Organizations needing multi-LLM routing, load balancing, and failover across various AI providers to ensure reliability and optimize costs.
Enterprises focused on token-based cost management and usage quota enforcement for LLMs to control expenditures.
Teams implementing prompt engineering, including templating, decoration, and semantic prompt guards, to enhance model performance and safety.
Organizations requiring robust security for AI-native systems, including PII sanitization and content moderation, to prevent data leakage and ensure compliance.

how to use

How to Use Kong AI Gateway

Utilizing Kong AI Gateway involves integrating it into an existing Kong Gateway deployment or setting up a new instance to manage AI traffic. The process typically begins with configuring routes and services for LLM providers and then applying AI-specific plugins.

1Deploy Kong AI Gateway, either as an extension to an existing Kong Gateway instance or as a standalone deployment.
2Configure services and routes to direct traffic to various LLM providers (e.g., OpenAI, Anthropic, AWS Bedrock).
3Implement AI-specific plugins for prompt compression, semantic caching, and dynamic model routing.
4Apply security policies such as PII sanitization and content moderation to LLM traffic.
5Utilize the observability features to monitor token usage, latency, and error rates for AI applications.
6Integrate with Kong Konnect for centralized management, discovery, and governance of MCP servers and AI-native tools.

Cons

−Primarily targets organizations already invested in the Kong ecosystem, potentially increasing adoption friction for new users.
−The plugin model, while flexible, can require careful and extensive configuration for advanced AI proxying, sanitization, and caching.
−Some public reviews for Kong Inc. reflect broader API management maturity rather than specific AI agent governance depth, requiring validation of specific AI features.
−Perceived cost can be a concern for some users, particularly as usage scales, necessitating careful evaluation of pricing models.

Similar Tools

Kong AI Gateway vs Competitors

Kong AI Gateway differentiates itself in the market by integrating LLM-specific capabilities into a comprehensive, enterprise-grade API management platform. This contrasts with solutions that primarily focus on LLM routing or are offered as standalone services.

LiteLLM↗

LiteLLM provides a unified API to call all LLM APIs, offering features like retries, fallbacks, and logging across various models.

While LiteLLM offers robust routing and fallback for various LLMs, it is primarily a client library/proxy for interacting with models rather than a full-fledged API gateway with enterprise-grade policy enforcement and access control like Kong AI Gateway. It requires more manual setup for advanced API management features.

OpenRouterOn Stork

OpenRouter provides a single API endpoint to access a wide range of LLMs from different providers, often at competitive prices, and includes features like caching and prompt management.

OpenRouter simplifies access to many LLMs and offers some gateway-like features, but it is a hosted service focused on model access and cost optimization. It doesn't offer the same level of on-premise deployment, custom policy enforcement, or deep integration into an existing enterprise API management ecosystem that Kong AI Gateway provides.

Portkey.aiOn Stork

Portkey.ai offers an AI gateway with features like caching, retries, fallbacks, and observability for LLM applications, along with prompt management.

Portkey.ai provides many similar LLM-specific gateway features like caching and routing. However, it is a dedicated AI gateway service rather than an extension of a broader enterprise API management platform like Kong, meaning it might not integrate as seamlessly into existing Kong-based infrastructure for general API governance.
