Lunar.dev provides that layer—serving as a unified API Gateway for AI, delivering: - **Live API Traffic Visibility:** Get real-time metrics on latency, errors, cost, and token usage across all outbound traffic, including LLM and agent calls. - **AI-Aware Policy Enforcement:** Control tool access, throttle agent actions, and govern agentic traffic with fine-grained rules. - **Advanced Traffic Shaping:** Apply rate limits, retries, priority queues, and circuit breakers to manage load and ensure reliability. - **Cost & Performance Optimization:** Identify waste, smooth traffic peaks, and reduce overuse of costly APIs through smart gateway policies. - **Centralized MCP Aggregation:** Streamline operations by consolidating multiple MCP servers into a single gateway, enhancing security, observability, and management. ## Choose Your Path Lunar.dev is composed of two major components: - [**Lunar Proxy**](https://github.com/TheLunarCompany/lunar/tree/main/proxy#readme) – our core API gateway and control layer - [**Lunar MCPX**](https://github.com/TheLunarCompany/lunar/tree/main/mcpx#readme) – a zero-code aggregator for multiple MCP servers with unified API access Explore the one that fits your needs—or use both for a full-stack solution. ## Open Source at the Core This project was born out of the need for a more robust, production-ready approach to managing third-party APIs. It remains open-source at its core and free for non-production/personal use. For production environments, we offer advanced features through guided onboarding and platform tiers; [visit our website](https://lunar.dev) or reach out directly for more information
