Why I built it

Useful diagnostics should be understandable and immediate.

Windows exposes rich system data, but finding it usually means jumping between settings, management consoles, and commands. SystemSage gathers those signals into one keyboard-driven interface with human-readable results.

It stays deliberately small: one native executable, no package manager for users, no account, no cloud service, and no resident agent consuming resources in the background.

What it checks

One tool for the questions that matter.

Reports that travel

From a live check to a clear health report.

The complete diagnostic collects system signals stage by stage, then creates a visual PDF dashboard with a health score, metric bars, recommendations, plain-English guidance, and a technical appendix.

  • Interactive output for people
  • Stable JSON output for automation
  • Local-first and read-only by default
