GatewayZ
A production-ready, enterprise-grade AI Model Gateway that provides a unified OpenAI-compatible API to access 100+ AI models from 30+ providers (OpenAI, Anthropic Claude, Groq, Together AI, Fireworks, DeepInfra, Hugging Face, Google Vertex, xAI Grok, and many more). It acts as a drop-in replacement for OpenAI endpoints with advanced routing, failover, load balancing, monitoring, billing, and security features. Ideal for apps, agents, or platforms needing reliable, cost-optimized multi-LLM access without vendor lock-in.
The Challenge
As companies scale their AI integrations, managing dozens of API keys, model rate limits, and latency spikes across various LLM providers (OpenAI, Anthropic, Google, Groq, etc.) becomes extremely complex. Relying on a single provider creates critical single-points-of-failure and vendor lock-in. Developers need an easy way to aggregate multiple LLMs under one standard API with built-in fallbacks, usage tracking, and cost optimization, without introducing latency.
Our Solution
We built GatewayZ, a highly performant and secure AI gateway. Using Next.js for a sleek, enterprise-grade dashboard, FastAPI for a sub-millisecond routing proxy, and Supabase for real-time tracking, billing, and developer configuration. The gateway implements smart routing, automatic failover to alternative providers when a model goes down or is rate-limited, load-balancing across API keys, and comprehensive usage telemetry. The proxy is fully Dockerized for simple local and production cloud scaling.
The Results
- Drop-in OpenAI-compatible API supporting 100+ models out of the box
- Up to 40% cost reduction by automatically routing to cheaper model providers
- Sub-millisecond routing overhead, keeping LLM response times ultra-fast
