Vercel Labs' deepsec Is an Agent-Powered Vulnerability Scanner You Run on Your Own Infrastructure — and It Tells You Scans Cost Thousands
vercel-labs/deepsec (7,639 stars, +579 today on GitHub Trending TypeScript, last pushed 2026-08-13) is a security harness that drives coding agents over an existing large-scale repo, with configurable thinking levels, parallelization across multiple machines, and resumable interrupted scans. It runs a free pattern-based pass first, then optional AI review stages. Unusually for a vendor-adjacent tool, the README is blunt about economics — scans 'can cost thousands or even tens-of-thousands of dollars for large codebases' — and cites no CVE counts or detection benchmarks, so treat the efficacy claims as unquantified.
