You write prompts. We write patches.
Your AI is a brilliant pattern-matcher and a terrible security engineer. Hardenator catches what it misses — at generation time, not six weeks after you ship to production.
The numbers nobody wants to print on the pitch deck.
Three layers of defense. One install.
Intercept at generation time
Plugin hooks into Claude Code and Cursor. When the AI tries to write a service_role key to a frontend file, we block it before the file hits disk.
- Claude Code plugin
- Cursor .mdc rules
- VS Code extension (Bolt, Replit, Windsurf)
- Claude Managed Agents skill

Semgrep-based CLI runs in your editor, pre-commit hook, and CI. 100+ rules tuned specifically for AI failure modes. False-positive rate under 8%.

Auto-fix as a pull request
Every fixable finding becomes a PR with a patch you can merge in one click. You review, not triage. Never auto-merged — you stay in control.
- GitHub App auto-PR
- Claude Sonnet 4.7 for complex fixes
- Plain-language breach explanations
- One-click rollback
100+ rules. Open source. Forever free.
Every pattern Hardenator catches is published as a public Semgrep rule under MIT license. Security researchers contribute. Community audits. Competitors can fork it — we'd prefer they did.
Your auto-fix + continuous protection is the paid layer. The knowledge is for everyone.
