Project Moonshot review
A beta, self-hosted toolkit for benchmark-driven LLM security testing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Project Moonshot is an open-source LLM evaluation toolkit for developers, compliance teams, and AI system owners. It combines benchmark testing with manual and automated red-teaming for LLMs and LLM applications. Testing spans capability, quality, and trust-and-safety categories, with support for prompt injection, jailbreak, data leakage, and unsafe output testing. Teams can work through the Web UI, interactive CLI, Python library, or Web APIs, while HTML reports and downloadable JSON results support review and sharing.
Its strongest differentiator is the combination of benchmark structure and adversarial testing. Moonshot includes benchmark cookbooks, recipes, datasets, metrics, and attack modules for adversarial prompt generation. Teams can also create custom datasets and custom benchmark tests, then connect custom LLM applications and endpoints. This makes it suitable for organizations that want repeatable evaluation alongside more exploratory red-teaming, rather than a tool focused only on one attack type or one model provider.
Moonshot is distributed as open source, with local installation and self-hosted deployment. It supports OpenAI, Anthropic, Together, Hugging Face, and custom LLM applications, giving teams several starting points for provider-connected testing. The project is documented as beta, so teams should weigh that status when selecting a tool for ongoing security programs. Project Moonshot fits teams that value configurable benchmarks, multiple interfaces, and control over deployment. Teams seeking a commercially priced service or a more mature, broadly integrated platform should consider alternatives.
