Augustus vs Project Moonshot

Augustus is a free, self-hosted Go scanner for security professionals assessing large language models. It runs adversarial probes and produces vulnerability reports, with more than 210 probes across 47 attack categories, including jailbreaks, prompt injection, data extraction, safety benchmarks, and agent attacks. It supports 28 provider categories and 43 generator variants, including hosted providers, Ollama, and custom REST endpoints. More than 90 detectors cover approaches such as pattern matching, LLM-as-a-judge, HarmJudge, Perspective API, and unsafe-content detection; seven prompt transformations include encoding, paraphrase, poetry, low-resource-language translation, and case changes. Results can be written as tables, JSON, JSONL, or HTML. The project lists concurrent scanning, rate limits, retries, and timeout handling. Augustus compiles to a portable single binary and can be installed with Go or built from source; the README requires Go 1.27.0 or later. It is Apache 2.0 licensed. The project is intended for authorized security testing, and users are told to test only systems they own or have permission to assess. Provider API use may require credentials.

Project Moonshot is an open-source toolkit for evaluating the safety and reliability of large language models and applications. It runs benchmark tests using open-source datasets and metrics, and generates adversarial prompts to probe possible vulnerabilities and misuse. Users can build custom evaluations with their own datasets, optional prompt templates, metrics, and grading scales. Results appear in interactive HTML reports and downloadable raw JSON. Moonshot provides a Web UI, interactive command-line interface, library APIs, and Web APIs, with configurable connections to model providers including OpenAI, Anthropic, Together, and Hugging Face. Users can also create connectors for other models or applications hosted on custom servers. The toolkit implements benchmarks recommended in IMDA’s Starter Kit for safety testing LLM-based applications. Moonshot is free beta software under Apache License 2.0. Installation uses pip and requires Python 3.11; the Web UI additionally requires Node.js 20.11.1 LTS or later, and test assets are needed to run tests. The installation guide recommends Chrome for the Web UI and notes possible installation difficulties on x86 Macs with moonshot-data dependencies.
