LiteLLM is a genuinely excellent open-source proxy — huge provider/model coverage, self-hosted, free, and battle-tested by thousands of teams. What it doesn't give you out of the box is a governance product: budget enforcement, a policy engine, cost attribution, and audit evidence are all things you build yourself on top of it. Wardin ships that layer as the product, at the cost of narrower provider coverage today.
LiteLLM's provider breadth is not close — 100+ providers and models against our four families (Anthropic, OpenAI, Bedrock, Vertex/Gemini). It's also free and self-hosted, which matters if procurement or data residency rules you out of a hosted product outright, and its community and integration ecosystem has years of head start on ours.
Choose LiteLLM if you need the widest possible provider coverage, must self-host, or want to build a fully custom governance layer yourself and have the engineering time to do it. Choose Wardin if you'd rather get budget enforcement, policy, and audit evidence as a configured product on day one, on the providers that carry most production LLM spend.
