Open source, no closed core

Apache 2.0 end to end. Every routing strategy and core plugin ships in the OSS tier — nothing critical is paywalled.

Written in Go

A compiled gateway runtime designed for low overhead on the request path, without a Python proxy layer between your apps and providers.

MCP-native

A built-in Model Context Protocol server runs the agentic tool-use loop inside the gateway — for Cursor, Claude Desktop and custom agents.

Self-hostable by design

Run the gateway in your own VPC or on-prem. Keep provider keys and runtime control in your environment without a required Ferro-hosted control plane.

FAQ

Frequently asked questions

Answers for teams evaluating routing, governance, self-hosting, and provider strategy.

Talk to the enterprise team
What is an enterprise AI gateway?

An enterprise AI gateway is a control layer between applications and AI providers. Ferro Labs centralizes provider routing, OpenAI-compatible access, policy controls, usage telemetry, fallbacks, and cost visibility across 83 providers and 2,505 catalog models.

Can Ferro Labs run in our VPC or self-hosted environment?

Yes. The Apache 2.0 gateway is self-hostable, and enterprise deployments can be planned for customer-controlled VPC or on-prem environments where provider keys and runtime controls stay under your operating model.

Does Ferro Labs replace OpenAI or Anthropic SDKs?

No. Teams can keep OpenAI-compatible SDKs and point the base URL to Ferro Labs. The gateway then routes requests across approved providers and models without requiring application rewrites.

How does Ferro Labs improve LLM reliability?

Ferro Labs supports fallback chains, retries, load balancing, rate limits, and observability so platform teams can shift traffic when a provider is slow, unavailable, or no longer the best fit for a workload.

What governance controls are available?

Teams can standardize virtual keys, rate limits, audit logging, guardrails, content filters, budget controls, and deployment-level controls. Enterprise security reviews are available before production rollout.

Who is Ferro Labs AI Gateway built for?

Ferro Labs is built for platform engineering, product, and AI infrastructure teams that need one governed API for production LLM applications across OpenAI, Anthropic, Google Gemini, AWS Bedrock, Azure OpenAI, and other providers.
