Deepsec: AI-Powered Vulnerability Scanner for Large Codebases

I built Deepsec, an agent-powered security harness that runs on your own infrastructure to uncover hidden vulnerabilities in large repositories. By leveraging advanced AI models at maximum thinking levels, it identifies issues that traditional tools miss, even if the scan costs thousands of dollars. The system supports parallel execution across worker machines and resumes seamlessly if interrupted, making high-cost, high-value security reviews practical for teams.

Our customers have found the cost worth it for how quickly they were able to patch vulnerabilities that would have otherwise gone unfixed.

    > Subscriptions (Claude Pro/Max, ChatGPT Plus) are useful for evaluating deepsec but generally don't have enough headroom for full repo scans.

    > For real scans, use Vercel AI Gateway. One key covers both Claude and Codex, and the gateway's default quotas are sized for highly concurrent research.

    Okay...
