Show HN: LLM-Gateway – Zero-Trust LLM Gateway (opens in new tab)

I built an OpenAI-compatible LLM gateway that routes requests to OpenAI, Anthropic, Ollama, vLLM, llama-server, SGLang... anything that speaks /v1/chat/completions. Single Go binary, one YAML config file, no infrastructure.

It does the things you'd expect from this kind of gateway... semantic routing via a three-layer cascade (keyword heuristics, embedding similarity, LLM classifier) that picks the best model when clients omit the model field, weighted round-robin load balancing across local inference servers with health checks and failover.

The part I think is most interesting is the network layer. The gateway and backends communicate over zrok/OpenZiti overlay networks... reach a GPU box behind NAT, expose the gateway to clients, put components anywhere with internet connectivity behind firewalls... no port forwarding, no VPN. Zero-trust in both directions. Most LLM proxies solve the API translation problem. This one also solves the network problem.

Apache 2.0. https://github.com/openziti/llm-gateway

I work for NetFoundry, which sponsors the OpenZiti project this is built on.

Realistically if you want to use an OSS model instead of the big 3, you're faced with evalutating models/providers across all these axes, which can require a fair amount of expertise to discern. You may even have to write your own custom evaluations. Meanwhile Anthropic/OAI/Google "just work" and you get what it says on the tin, to the best of their ability. Even if they're more expensive (and they're not that much more expensive), you are basically paying for the priviledge of "we'll handle everything for you".
