Gemini to OpenAI API Converter

A simple reverse-proxy service that converts Google Gemini web interface into an OpenAI-compatible API. Developers can use Gemini's models with existing OpenAI client libraries without code changes. Target users: developers wanting to switch between AI providers or reduce costs.

The surge in AI provider fragmentation over the past 18 months has made vendor lock-in a real pain point — developers who standardized on OpenAI's SDK now face friction every time they want to test Gemini 2.0 or Flash for cost reasons. LiteLLM already does this exact thing as part of a broader multi-provider proxy, which is the real competitor here and offers Gemini-to-OpenAI translation for free. That incumbent makes the $500–2k/mo revenue band feel optimistic rather than conservative — charging for a single-provider shim when a free, well-maintained open-source tool covers the same ground is a hard sell. The most likely failure mode is that developers either discover LiteLLM or just write the 20-line adapter themselves, leaving the addressable paying market too thin to sustain even modest SaaS pricing.
