Deploy in seconds with zero configuration and get automatic failover, load balancing, semantic caching, and enterprise-grade features. ## Quick Start  **Go from zero to production-ready AI gateway in under a minute.** **Step 1:** Start Bifrost Gateway ```bash # Install and run locally npx -y @maximhq/bifrost # Or use Docker docker run -p 8080:8080 maximhq/bifrost ``` **Step 2:** Configure via Web UI ```bash # Open the built-in web interface open http://localhost:8080 ``` **Step 3:** Make your first API call ```bash curl -X POST http://localhost:8080/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "model": "openai/gpt-4o-mini", "messages": [{"role": "user", "content": "Hello, Bifrost!"}] }' ``` **That's it!** Your AI gateway is running with a web interface for visual configuration, real-time monitoring, and analytics. **Complete Setup Guides:** -
