Higress

Cloud-native API gateway with AI and Wasm extensibility

Higress is a cloud-native API gateway built on Istio and Envoy, offering AI model routing, MCP server hosting, and extensible Wasm plugins for traffic, security, and observability.

Overview

Overview

Higress delivers a production‑grade API gateway that combines the robustness of Istio/Envoy with AI‑focused capabilities. It unifies access to major LLM providers, supports the Model Context Protocol (MCP) for tool integration, and provides a rich UI console for management and observability.

Deployment & Extensibility

Developers can launch a full instance with a single Docker command or deploy via Helm in Kubernetes. The gateway’s plugin architecture relies on WebAssembly, allowing safe, hot‑updatable extensions written in Go, Rust, or JavaScript. Built‑in plugins cover traffic management, security (WAF, auth), and AI‑specific functions, meeting most enterprise scenarios out of the box.

Target Audience

Ideal for teams building AI agents, microservice platforms, or secure ingress points that need high‑throughput, low‑latency streaming and fine‑grained rate limiting. Enterprises benefit from Alibaba’s production validation and optional enterprise support.

Highlights

Production‑grade performance validated by Alibaba at massive scale
True streaming processing for request/response bodies
Wasm‑based extensibility supporting Go, Rust, and JavaScript
Built‑in UI console, auto TLS via Let’s Encrypt, and Docker‑first start

Pros

  • High throughput and low latency for AI workloads
  • Memory‑safe plugin isolation with hot updates
  • Unified management of LLM and MCP APIs
  • Comprehensive security and observability out of the box

Considerations

  • Steep learning curve for Istio/Envoy newcomers
  • Advanced features may require the enterprise edition
  • Kubernetes deployment adds operational complexity
  • Documentation may be fragmented across multiple repos

Fit guide

Great for

  • Enterprises needing a reliable AI gateway with load balancing
  • Developers building AI agents that call external tools via MCP
  • Teams requiring a customizable microservice ingress controller
  • Organizations prioritizing security, rate limiting, and observability

Not ideal when

  • Simple static websites without API requirements
  • Projects that cannot adopt Kubernetes or Istio
  • Use cases demanding a lightweight proxy without Wasm
  • Environments that require proprietary vendor lock‑in

How teams use it

MCP Server Hosting

Host remote MCP servers via Wasm plugins, enabling AI agents to invoke tools with unified auth, rate limiting, and audit logging.

AI Model Routing

Connect to multiple LLM providers through a single gateway, applying token rate limits, caching, and multi‑model load balancing.

Kubernetes Ingress Controller

Replace Nginx ingress with Higress, leveraging familiar annotations while gaining AI‑aware traffic management.

Security Gateway

Enforce WAF, JWT, OIDC, and other authentication strategies with built‑in plugins and automatic TLS management.

Frequently asked questions

How do I start Higress locally?

Run the provided Docker command; it pulls the all‑in‑one image, writes config to the current directory, and exposes UI (8001) and gateway ports (8080/8443).

Which LLM providers are supported?

Higress supports all mainstream model providers, both domestic and international, via a unified protocol.

Can I write my own plugins?

Yes, you can develop Wasm plugins in Go, Rust, or JavaScript and load them through the plugin mechanism.

Is enterprise support available?

Enterprise‑level support is offered by contacting the project maintainer via the listed email or social media accounts.

Do I need Kubernetes to use Higress?

Kubernetes is optional; Higress can run as a standalone Docker container, though Helm charts are provided for K8s deployments.
