Kong is an open-source API gateway and platform — providing the traffic management, security, observability, and transformation layer between API clients and upstream services. Kong's plugin ecosystem extends gateway functionality without code changes — authentication (JWT, OAuth, API keys), rate limiting, logging, caching, and transformation plugins applied to API routes. AI Gateway is Kong's emerging capability — providing LLM-specific proxy features for managing AI API traffic: rate limiting by token rather than request count, AI response caching to reduce duplicate LLM API calls, prompt injection detection, and cost tracking across different LLM providers. Konnect is Kong's managed control plane — managing Kong Gateway instances across cloud and on-premise deployments from a centralised cloud interface. Service Mesh integration extends Kong to east-west (service-to-service) traffic alongside north-south (client-to-service) API traffic. Developer Portal provides API documentation and consumer onboarding — enabling internal and external developers to discover, subscribe to, and use APIs through a self-service portal. Rate Limiting plugins protect upstream services from abuse — configuring request rate limits by consumer, IP, or credential with burst allowances. Analytics and monitoring provide API traffic visibility — request volumes, error rates, latency, and consumer usage patterns. With deployment across major enterprises and the open-source community, Kong validates as a widely adopted API gateway for high-traffic API management.
Kong AI runs as llm assistant software built around data and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, cli, and api, with API access for teams that want to embed it into their own products.
