OpenRouter made multi-model API access simple: one endpoint, hundreds of models, unified billing. But as your AI workload grows, you start noticing the cracks — markup fees eating into margins, limited model coverage for non-LLM tasks, and no self-hosting option for teams with compliance requirements.
Whether you need cheaper AI API pricing, broader model coverage (image, video, music generation), enterprise governance, or full self-hosting control, there's likely a better fit for your specific use case.
We tested 7 alternatives hands-on, compared real pricing, and ran actual API calls. Here's what we found.
