What is Higress?

Production-grade AI gateway for LLM API management, agent development, and multi-model integration with unified protocol conversion and semantic caching.

Higress is a production-grade AI-native API gateway built on open-source Istio and Envoy, integrating traffic scheduling, service governance, and security protection. It supports unified protocol conversion for 100+ LLM models, semantic caching, token management, and MCP service hosting. Available as free open-source and commercial cloud versions, it helps enterprises manage multi-model access, ensure data security, and reduce costs.

Key Features

Unified protocol conversion for 100+ LLM models
Model-level fallback
Semantic caching for token savings
Token usage tracking and rate limiting
Data privacy protection and content filtering
MCP service hosting and protocol offloading
Integration with Dubbo, Nacos, Sentinel
WASM plugin extension
Multi-registry support
Authentication and authorization

Use Cases

Enterprise AI teams integrate multiple LLM APIs (OpenAI, Claude, domestic models) through a single gateway, reducing model switching complexity and ensuring high availability with automatic fallback.
Developers building AI agents use Higress to manage MCP service access, enabling rapid conversion of existing services to MCP servers without deep protocol knowledge.
Platform engineers deploy Higress as a unified API gateway for both traditional microservices and AI endpoints, simplifying traffic governance and security policies across the stack.
Data scientists leverage semantic caching to cache similar query results, cutting token costs by up to 50% and reducing response latency for repeated AI inference requests.
Operations teams monitor and control token usage per consumer, setting quotas to prevent abuse and generating usage analytics for cost allocation.
Security officers configure data privacy filters to mask sensitive information before sending to external LLMs, ensuring compliance with data protection regulations.
Cloud architects replace legacy Nginx Ingress with Higress to gain AI-native capabilities like model routing and protocol adaptation, future-proofing their infrastructure.
