Introduction
WidTronic is a lightweight, Python-based desktop widget engine designed for gamers and performance-focused users who want beautiful widgets without the resource cost.
What is WidTronic?
WidTronic is a 20MB disk / 20MB RAM desktop widget engine built entirely in Python. It renders customizable widgets — clocks, system monitors, weather info, and more — directly on your desktop with minimal overhead.

WidTronic is 100% open source. Every line of code is available on GitHub. Audit it, modify it, redistribute it freely.

FAQ
Frequently asked questions about WidTronic.
General
Is WidTronic safe to use?
Yes. 100% open source Python code. Inspect every file on GitHub. No network calls (except optional weather), no data collection, runs in user space without admin privileges.
What is WidTronic exactly?
A Python-based desktop widget engine. Displays customizable widgets (clock, date, system monitor, weather) directly on your Windows desktop. Ultra-lightweight alternative to Rainmeter.
Why WidTronic over Rainmeter?
Roughly 1/3 the RAM, smaller disk, open source, simpler config via single JSON. Rainmeter has more plugins — WidTronic focuses on doing a few things extremely well.
Technical
Does it work on macOS or Linux?
Windows 10/11 only currently. Widget rendering uses Windows-specific desktop composition APIs. Linux/macOS is on the roadmap.
Can I create custom widgets?
Plugin API for custom widgets is in early development. Currently you can customize existing widgets through config.
Multi-monitor support?
How to completely uninstall?
Delete the WidTronic folder. No registry entries, no AppData, no services. Fully portable.
Troubleshooting
Widgets not showing?
Verify "visible": true in config.json. Check the system tray icon exists. Try running widtronic.exe again.
Config changes not applying?
Validate your JSON (no trailing commas, proper quotes). WidTronic silently ignores invalid config. File watcher has a 1-second debounce.
High CPU usage?
Set "animations": false and increase system monitor "refresh_interval" to 5+ seconds.
