CST VerdictBased on our analysis of core features, integrations, here is our conclusion:
Security and platform teams managing multiple LLM providers across agents and applications need Lunar.dev AI Gateway to enforce consistent data governance before requests leave your infrastructure; the combination of prompt sanitization, fine-grained access controls with human-in-the-loop gating, and full token-level auditing directly addresses the control gap that exists between your apps and third-party LLM APIs. The free tier lets you test rate limiting and observability without commitment, which matters when LLM spend is unpredictable. Skip this if you're looking for a single unified platform covering fine-tuning, model governance, and post-response content filtering; Lunar.dev is explicitly designed for outbound traffic management and doesn't replace model evaluation or output scanning tools.
