Higress.AI

Higress.AI is a production-grade, cloud-native AI API gateway built on Envoy and open-sourced by Alibaba. It inherits the high performance and high stability of traditional traffic and microservice gateways, while providing the infrastructure for enterprises to connect large models and build AI agents with unified management, cost control, and security protection.

Core Capabilities

• Multi-model proxy and failover: A unified OpenAI-compatible API connects to hundreds of LLMs, with intelligent multi-model fallback to keep services highly available.
• AI caching and cost control: Precise-match and semantic-level AI response caching, combined with token-consumption-level rate limiting, significantly cuts API call costs and latency.
• MCP service hosting: Built-in hosted MCP servers and the openapi-to-mcpserver tool turn existing Dubbo/REST interfaces into toolsets LLMs can call within seconds.
• Dynamic Wasm plugin extensions: Developers can write custom plugins in Go, Rust, JS, and other languages, hot-updating content filtering, security authentication, and other functions.
• Jitter-free hot config updates: Underlying architectural advantages let configuration take effect in milliseconds, completely solving the long-connection drops and traffic jitter caused by traditional gateways (like Nginx) reloading.
• Unified multi-gateway architecture: Fuses traffic gateway, microservice gateway, and security gateway capabilities, helping enterprises greatly simplify system architecture and reduce resource consumption.

Best For Best suited to mid-to-large enterprise engineering teams with strict demands on data privacy, system performance, and cost control, plus backend engineers and system architects who want to AI-enable existing microservice architectures quickly.

Unique Advantages Compared with ordinary lightweight API proxies, Higress.AI delivers true enterprise-grade millisecond hot updates and extremely high concurrency; between commercial hosting and self-hosted open source, it gives enterprises maximum freedom and effectively avoids single-platform lock-in.

Editor's Verdict A flagship work of cloud-native architecture meeting the AI era, Higress.AI is indispensable infrastructure for building large-scale AI applications. If you're looking for an enterprise AI gateway that stays rock-solid in production while finely managing hundreds of model APIs and optimizing token consumption, this is currently the strongest, most forward-looking open-source choice available.
