Author Builds OSV.dev Vulnerability Lookup Tool
A developer discovered the OSV.dev open CORS JSON API and had Claude Code build an HTML tool that accepts a pyproject.toml, requirements.txt, or a GitHub repository name to list reported vulnerabilities. The tool queries OSV.dev in-browser without a backend, returning dependency vulnerability reports. This enables quick client-side dependency scans during development.
Scoring Rationale
Useful, immediately usable tool with direct client-side scanning; limited novelty and single-source reporting reduces broader impact.
