A web-based, all-in-one system scanner — one local Flask server opens a dark dashboard that inspects hardware, security, battery health, processes and more across Windows, Linux and macOS, with a live health score and JSON export.
Figuring out what's actually going on inside a computer usually means a dozen separate tools — one for hardware, one for temperatures, one for the battery, another for a virus scan — most of them platform-specific and none of them giving you a single, honest picture. I wanted one thing you can run on any machine that answers "is this computer healthy?" in a glance.
SystemGuard Pro runs a small local Flask server and opens a dark, animated dashboard in the browser — no GUI framework to install. Behind it, 13 scanner modules cover system, CPU, memory, disk (with SMART), GPU, network, battery health, security (firewall/antivirus/SSH), processes, startup items, a virus quick-scan and a heuristic hardware timeline. It's cross-platform (Windows, Linux, macOS) with graceful fallbacks, and it degrades honestly: run without admin and it tells you which checks are limited rather than pretending.
Results are rolled into a single animated health score and a Critical Findings panel grouped by severity, and the whole report exports to JSON.
A working, cross-platform diagnostics tool that turns a scattered chore into one dashboard — 13 scanners, a real-time health score, severity-ranked findings and JSON export, all in the browser. On a test run it surfaced concrete, honest findings (high swap usage, a disabled firewall) and scored the machine 93/100 — a utility that measures and reports rather than guesses.
