Score: 6.3/10 (Innovation: 5, Technical: 6, Documentation: 8, Utility: 6)

NoVul is a macOS menu bar app that aggregates vulnerability and exposed-secret findings across local projects, Homebrew packages, global tools, runtimes, and AI coding tools, ranking issues using OSV, CISA KEV, EPSS, and end-of-life data. It offers a fix plan, private local scanning mode, and MCP/CLI integration so coding agents can read and remediate findings. The combination of desktop vulnerability triage with agent-driven fixes is a practical, well-scoped use of existing data sources.

Target audience: macOS developers, security engineers, devops
