BaronRouter is a free AI gateway that brings 40+ AI providers into one chat and OpenAI-compatible API. Compare models, save prompts, create personas, manage projects, upload files, and keep conversations in one place. Smart routing, retries, and automatic fallback keep your AI workflow going when a provider is rate-limited, unavailable, or fails.

I originally built BaronRouter for my own smart home setup. I needed free AI models to help control my home, create shopping lists, update gym weights, and handle small everyday automations. The problem was that free models were sometimes rate-limited, unavailable, or just down, which made the whole setup unreliable. So I built BaronRouter: a free AI gateway that can route prompts across 100+ AI providers, retry when something fails, and automatically fall back to another compatible model. It has grown into a full chat and API platform with model comparison, personas, projects, file uploads, prompt saving, memory, and an OpenAI-compatible API. I’d love your feedback, especially from people using AI for automations, smart home workflows, or developer tools.

finally an ai router that doesn't make me juggle five browser tabs. the fallback routing saved me when openai started throwing 429s mid-project, and having all my prompts in one place is such a relief.
