LLM Load Balancer Gateway

A unified gateway that routes API requests across multiple LLM providers (OpenAI, Anthropic, local models) with automatic load balancing. Developers using multiple LLM APIs can reduce costs and avoid vendor lock-in by automatically routing to cheaper or available providers based on real-time conditions.

LiteLLM already does most of this and is open-source, which sets a brutal baseline — any paid product here needs a defensible layer on top, whether that's enterprise SLAs, a hosted managed version, or analytics that LiteLLM's self-hosted setup doesn't provide. Timing is real: the proliferation of competing frontier models in 2024-2025 (GPT-4o, Claude 3.x, Gemini, Llama 3) means teams genuinely do span multiple providers now, so the routing problem isn't theoretical. The $2k-10k/mo revenue band is plausible for a thin managed-hosting play targeting small engineering teams who don't want to run infrastructure, but it's a ceiling unless you land larger accounts who care about compliance or uptime guarantees. The single most likely failure mode is that the open-source alternative is good enough and the target customer is exactly the kind of developer who will self-host rather than pay.
