CostLayer vs LiteLLM
LiteLLM is a powerful open-source proxy that unifies 100+ LLM providers behind a single API. It gives you full traffic control, load balancing, and fallback routing — and it’s free to self-host. CostLayer takes a different approach: cost visibility and optimisation without a proxy, without code changes, and without infrastructure to maintain.
