CompScan: Your computer's health doctor. Fully local, private, free (Rust)

#cli #privacy #rust #showdev

I built CompScan: a fully local system health tool that scans your machine, finds what's slowing you down, spots security issues, and fixes things with one command. Nothing ever leaves your computer.

Why it exists

Most "optimization" tools are either cloud-heavy, full of telemetry, or one-off scripts. I wanted one CLI that's private, cross-platform, and actually useful for developers.

What it does

  • Health check: CPU/RAM hogs, disk space, caches (often 2-15 GB reclaimable)
  • Security: SSH keys, credentials, firewall, permissions. Score out of 100.
  • Habits: late-night usage, marathon sessions, suggests breaks
  • One-click actions: cleanup caches, temp files, logs (trust-level gated)

Tech

Rust, ~3 MB binary, redb for storage, optional Ollama for deeper reasoning. macOS, Linux, Windows.

Install 

curl -fsSL https://raw.githubusercontent.com/vvk147/comp-scan/main/install.sh | bash
Enter fullscreen mode Exit fullscreen mode

Or: cargo install --path . from the repo.

If you care about privacy and a fast machine, give it a try: github.com/vvk147/comp-scan
