A comprehensive toolchain for secure LLM API access. Route across every credible free-tier LLM provider utilizing 1.7 Billion free tokens per month. Bring your own keys; we just point requests at whichever provider still has budget left.
Over 100+ free models across 16 providers. Mistral alone contributes ~1B; everything else is bonus. Get your keys below, drop them in KeyKing, and never pay for tokens again.
Whether you are vibe-coding locally or scaling a serverless production app, KeyKing provides the ultimate infrastructure for LLM API security.
Ideal for "Vibe-coding". Run the KeyKing local proxy that binds to localhost:8787. Route your local AI assistants and scripts through the proxy to automatically securely attach credentials and balance limits without exposing your plaintext API keys in dotfiles.
Deploy to production with zero friction using @keyking/sdk. Purpose-built for serverless environments (Vercel, AWS Lambda, Cloudflare Workers). It natively unpacks exported encrypted vaults in memory, providing secure multi-provider routing on the edge.
Your mission control for credentials. Securely store and manage all your LLM API keys locally. Generate encrypted vault files that you can safely commit to your repository or bundle in your serverless deployments to be unpacked by the KeyKing SDK.
Experience the routing engine without downloading the desktop client. Switch between developer code integrations below, and click the simulation button to watch Key King's local proxy decrypt, select quotas, execute, and stream responses.
