Higress

What it is

Open-source cloud-native API gateway built on Istio and Envoy, extended with Wasm plugins (Go, Rust, JS). The README describes AI gateway functions: unified access to mainstream LLM providers, observability, multi-model load balancing, token rate limiting and caching, plus hosting of MCP servers; an openapi-to-mcp tool converts OpenAPI specs into remote MCP servers.

Maker and licence

Started inside Alibaba (per the README) and now a CNCF Sandbox project. Licence: Apache-2.0 (GitHub). Repo github.com/higress-group/higress (alibaba/higress redirects there): 9,500 stars and latest release v2.2.5 (2026-10-04) on 2026-10-08. A commercial Alibaba Cloud AI Gateway is listed as the managed edition. See Alibaba.

Position

API gateway with MCP and LLM gateway (also usable as Kubernetes ingress and microservice gateway).

Capabilities

LLM provider routing; MCP gateway for tool-call governance with MCP proxying and translation; an MCP market on the project site; WAF and authentication plugins; service discovery from Nacos, Consul and similar registries.

MCP spec support

The project site news item mentions support for the “MCP 2026-07-28” revision; I did not open the underlying docs.

Maturity

CNCF Sandbox status (README and site, 2026-10-08).

Fit and limits (opinion)

Fits teams already on Envoy/Istio or in the Alibaba ecosystem wanting plugins in Wasm; the plugin model is more work than a purpose-built agent proxy.

Pricing

Open source; commercial edition priced via Alibaba Cloud (link the vendor page).
