Delta Widgets vs Themia

Delta Widgets is a free, open-source Windows app for creating desktop widgets without code. Its visual drag-and-drop editor supports built-in templates, layouts made from scratch, custom HTML/CSS, and widgets built from URLs. Widgets can display live time, system statistics, media information, and weather. Preinstalled options include date and time, media controls, an audio visualizer, weather, disks, RAM, CPU, and battery. Expressions and variables insert or format dynamic values in text and images. URL widgets can embed webpages, dashboards, web apps, or online tools, and are sandboxed to display external content only. An optional bring-your-own-key assistant supports OpenAI, Anthropic, Google, Ollama, and OpenRouter; the maker says provider keys are encrypted on the device. Compatibility is listed for Windows 10 and Windows 11, with Windows 10 April 2018 or later required. The download page reports anonymous install and widget-enable events through Mixpanel, without personal-data tracking. The project uses the GPL-3.0 license, with documentation, GitHub issues, and Discord support.

Themia is a Windows desktop widget app for arranging information and tools on a computer desktop. It supports Windows 10 and Windows 11, and its library lists 50 widgets across six categories, including office, online, system, layout and utility widgets. Users can create separate desktop layouts and switch between them. Widgets support actions such as resizing, scrolling, checking off tasks, composing email and controlling music playback. Listed connections include Google, Microsoft, IMAP, CalDAV, CardDAV, OneDrive, GitHub, Claude, RSS and weather services. The app runs locally and works offline, although email, calendar and weather widgets need internet access to refresh. The maker says settings, notes, layouts, files and connected-account data remain on the user's computer. Credentials and OAuth tokens are encrypted at rest with Windows DPAPI, and data sent by Themia travels over TLS. The Free plan includes 10 widgets and two screens. Pro costs $19, paid once and adds unlimited widgets and screens, use on up to five devices, updates within v1.x and priority support.
