Netherite

Netherite scans any GitHub repository for security problems the way a security engineer would: it reads the whole codebase, tells you what is actually exploitable rather than listing theoretical findings, and produces the exact fix. Every finding carries a file, a line number, and the reasoning written out in full, and the fix comes as a prompt scoped to one file with constraints already stated, ready to paste into your coding agent. That prompt-shaped output is the genuinely modern part, acknowledging that the repair workflow now runs through Claude Code or Cursor rather than a human with a patch file. The blunt positioning, fixing weak AI-slop code, targets the real accumulation of quickly generated code shipping with real vulnerabilities. A sample report on the site lets you judge finding quality before pointing it at anything sensitive. For solo developers and small teams shipping fast without a security review step, this is a cheap audit habit, with the usual caveat that automated scanning complements rather than replaces real review for critical systems.
