Local scanner that finds leaked API keys and secrets left behind by previously installed developer tools.

The pain

Developers install tools (npm packages, CLI utilities, Docker images, etc.) that may store credentials in config files, environment variables, or cache directories. When uninstalled or when switching machines, these secrets remain accessible to anyone with filesystem access. A developer has no straightforward way to audit what secrets are currently exposed on their machine.

The gap

Existing solutions are either cloud-based (requires uploading secrets), enterprise-focused (expensive, overkill), or require manual configuration per tool. No lightweight, offline-first scanner exists that works out-of-the-box for common developer tools and locations.

Build angle

Start with a CLI tool that scans standard secret locations (dotfiles, node_modules, .aws, .ssh, .docker, browser extensions, etc.) using pattern matching and entropy detection. Focus on zero-configuration scanning for the top 20 tools developers actually use. Charge per-seat or as part of a developer security suite.

Strengths

  • Clear, specific problem affecting millions of developers daily
  • Low barrier to initial MVP, pattern matching + file scanning is straightforward
  • Natural upsell path to continuous monitoring, team dashboards, or integration with CI/CD
  • Defensible moat through tool-specific knowledge and detection patterns
  • Works offline, addressing privacy concerns that block adoption of cloud alternatives

Risks

  • Market may already have partial solutions (git-secrets, truffleHog, Snyk); need to validate actual usage gaps
  • Monetization unclear, developers expect free security tools; hard to charge individuals
  • False positives on entropy detection could create alert fatigue and kill adoption
  • Requires ongoing maintenance as tools and secret formats evolve
  • Enterprise sales cycle slow; consumer adoption limited without distribution channel
