Desktop Widgets vs Nexus

Desktop Widgets is a marketplace of desktop mini-apps for trading, research, monitoring, and automation. Its site describes widgets being installed in one click and running natively across Windows, macOS, and Linux, while also promoting a Windows runtime and saying macOS and Linux are coming soon. Traders, operators, researchers, and developers are named as intended users who can combine mini-apps into an always-on workstation. Developers can make TypeScript widgets with @desktopwidgets/sdk, using Claude, GPT, or another model; the listed build and publishing tools include an MCP server, REST API, and CLI. Uploads are pending review, and automatic publication through signing is planned for Phase 3. The runtime is described as sandboxed by default, with gate-enforced capabilities. The Free Trial costs 0.00 USD for 7 days and includes all 31 widgets and themes and customization, with three device activations and no credit card required. Professional is $34.99, paid once purchase; Enterprise is $149.99, paid once purchase. Both paid plans include one year of updates, then optional paid maintenance renewals for further updates.

Nexus combines PC hardware monitoring, fan and pump control, and RGB lighting in one free app. It shows live CPU, GPU, memory, network, disk, fan, and temperature readings, with per-game FPS history on Windows. Its GPU-rendered lighting engine offers screen sync, audio sync, and Game Sync. Users can set fan and pump curves from any system temperature sensor or leave selected devices on BIOS or firmware settings. Nexus uses its own device drivers and a bundled OpenRGB build; hardware support depends on the exact model. A phone browser can act as a remote panel, using an encrypted relay outside the home network and switching to a direct connection when possible. The app works locally and offline without an account, while optional anonymous telemetry can be controlled in settings. Nexus runs on 64-bit Windows 10 or 11, Apple Silicon Macs, and x86-64 Linux. It has no builds for Windows on ARM, Intel Macs, or ARM Linux. Companion iOS and Android apps are not yet in the app stores.
