Delta Widgets review
A free, open-source Windows widget builder with broad customization options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Delta Widgets is a free, open-source desktop widget maker for Windows 10 and 11. It is aimed at Windows users who want to create custom desktop displays without being limited to fixed widget designs. The visual drag-and-drop builder supports layouts for date and time, media, weather, disks, RAM, CPU, battery, system statistics, audio visualization, custom HTML, and URL or web content. Users can publish widgets to the desktop and control whether they are enabled or disabled.
The main strength is breadth within the desktop-widget category. Delta Widgets combines visual construction with custom HTML, CSS, and JavaScript, giving users a path from simple arrangements to more tailored interfaces. Templates can provide a starting point, while template cloning, dynamic variables, and expressions support repeatable designs and changing content. System information widgets, media playback information, and audio visualizations also make it suitable for dashboards that combine monitoring with desktop personalization. Tauri is listed as an integration, and URL widgets can embed webpages directly.
According to the vendor’s description, Delta Widgets is completely free and open source, so its published model does not divide features across paid tiers. That makes it a practical choice for Windows users who want customization without a subscription. The main boundary is platform support: the product is Windows-only, which rules it out for users seeking a cross-platform widget tool. It also offers deeper control than a fixed widget catalog, but custom HTML, CSS, or JavaScript features may suit technically inclined users better than those who want only ready-made layouts. Choose Delta Widgets for flexible Windows desktop widgets; consider an alternative if broader platform coverage is essential.
