OpenGem – A Load-Balanced Gemini API Proxy (No API Key Required)
Hi HN! I built OpenGem, an open-source, load-balanced proxy for the Gemini API that requires absolutely no paid API keys. GitHub: https://github.com/arifozgun/OpenGem The Context: Like many developers, I was constantly hitting "429 Quota Exceeded" errors while building AI agents and processing large payloads on free tiers. I wanted to build freely without calculating API costs for every test request. How it works: I reverse-engineered the official Gemini CLI authentication to get standard API access. However, a single free Google account quota depletes quickly. To solve…
OpenGem – A Load-Balanced Gemini API Proxy (No API Key Required) launched on February 22, 2026 with 7 votes, #1,386 of 16,628 launches that month and more than 75% of that year's launches.
What it does
OpenGem turns one or more Google accounts into a local, load-balanced Gemini gateway. It exposes the native Gemini API shape and also accepts OpenAI Chat Completions and Anthropic Messages requests, so most SDKs can point at your OpenGem server with only a base URL change. It is designed for personal, educational and research usage. You run the gateway, connect your own Google accounts, create your own API keys, and monitor usage from the admin console.

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986.
