Higress.AI

Managing multiple LLM APIs across a growing AI Agent ecosystem is complicated — handling failovers, costs, rate limits, and security at scale requires serious infrastructure. Higress is an AI-native API gateway built on Istio and Envoy, extensible with Wasm plugins in Go, Rust, or JavaScript. It provides everything enterprises need to build and manage AI Agents and LLM APIs: flexible multi-model switching with automatic failover and retry, content safety and compliance for LLM outputs, semantic caching to reduce costs, multi-API Key load balancing, Token quota management and rate limiting, traffic shaping and canary releases for AI workloads, and call cost auditing. Whether you're running an AI Agent platform or managing a complex LLM API infrastructure, Higress gives you the control and reliability to do it at enterprise scale.
