LiteLLM vs OpenRouter: I Used Both. Here's Where Each One Actually Broke.
The article compares LiteLLM and OpenRouter, two different tools for routing large language models. LiteLLM is a self-hosted open-source proxy, while OpenRouter is a managed cloud aggregator. The author found that neither tool was the right long-term answer for their setup due to limitations such as scalability and governance issues.
- ▪LiteLLM is an open-source Python library and proxy server that gives a unified API in front of 100+ model providers.
- ▪OpenRouter is a managed cloud service with a 5.5% fee on credit purchases and no self-hosted models.
- ▪The author ran LiteLLM in staging for six weeks and used OpenRouter for a parallel workload to compare the two tools.
