Lunar.dev provides an open-source API gateway and control layer designed to manage, govern, and optimize third-party API consumption, particularly for AI agents and autonomous workflows. It offers real-time visibility into API traffic, AI-aware policy enforcement, advanced traffic shaping, and cost optimization, acting as a central mediation layer for external service interactions.

How It Works

Lunar.dev functions as a proxy that sits between applications/AI agents and external APIs. It intercepts and analyzes API calls, applying configurable policies for rate limiting, retries, and circuit breaking. Its AI-aware capabilities allow for fine-grained control over tool access and agentic traffic, with a focus on providing live metrics for latency, errors, cost, and token usage. The architecture supports consolidating multiple MCP servers for unified API access and management.

Quick Start & Requirements
