Nothing ever leaves your computer.</p> <h2> Why it exists </h2> <p>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.</p> <h2> What it does </h2> <ul> <li> <strong>Health check:</strong> CPU/RAM hogs, disk space, caches (often 2-15 GB reclaimable)</li> <li> <strong>Security:</strong> SSH keys, credentials, firewall, permissions. Score out of 100.</li> <li> <strong>Habits:</strong> late-night usage, marathon sessions, suggests breaks</li> <li> <strong>One-click actions:</strong> cleanup caches, temp files, logs (trust-level gated)</li> </ul> <h2> Tech </h2> <p>Rust, ~3 MB binary, redb for storage, optional Ollama for deeper reasoning. macOS, Linux, Windows.</p> <h2> Install </h2> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>curl <span class="nt">-fsSL</span> https://raw.githubusercontent.com/vvk147/comp-scan/main/install.sh | bash </code></pre> </div> <p>Or: <code>cargo install --path .</code> from the repo.</p> <p>If you care about privacy and a fast machine, give it a try: <a href="https://github.com/vvk147/comp-scan" rel="noopener noreferrer">github.com/vvk147/comp-scan</a></p> cli privacy rust showdev
