Open-source gateway simplifies LLM API key management and failover

By PulseAugur Editorial · [1 sources] ·

A developer has created an open-source tool called Palimpsest Gateway to manage multiple API keys from various LLM providers like OpenAI, Anthropic, and Google Gemini. This self-hosted gateway acts as a central point, pooling keys, handling automatic failover when one key hits its limit or errors, and maintaining session continuity. The tool aims to solve the common infrastructure problem of applications breaking due to exhausted API quotas by providing a unified, OpenAI-compatible endpoint that encrypts keys at rest and offers a usage dashboard.

    How I Built an Open-Source LLM Key-Pool Gateway (and Why You Might Want One)

    <p>I hit a wall that felt familiar to anyone building with LLMs.</p> <p><strong>The problem:</strong> I had three OpenAI keys (two free-tier, one paid), an Anthropic key, and a Gemini key. Every app I built needed its own logic to handle rate limits, and quota exhaustion. When on…
