OpenAlive prevents your Windows workstation from going idle by simulating subtle mouse movements and optional keystrokes at configurable intervals — so your status stays green and your screen stays on while you work. It runs on your schedule: active only during your work hours, with an automatic lunch-break pause, and a manual toggle anytime. Lives quietly in the system tray — no admin rights, no drivers, no physical jiggler — with a color-coded icon (Active / Inactive / Outside hours / Lunch). Also available as a portable .zip alongside the installer. Free and open source (GPLv3), zero telemetry — no network requests, nothing leaves your machine. Available in 8 languages: English, Español, Português (BR), Français, 日本語, 中文简体, 한국어, Kreyòl ayisyen. Single .exe, ~4 MB installed, ~5–15 MB RAM at idle.

Dnote is a personal knowledge management tool focused on easily capturing, organizing, and retrieving technical notes such as code snippets, terminal commands, and short documentation, all while keeping content accessible and searchable. It is designed around fast, distraction-free workflows that let users jot down notes quickly from the terminal or a web interface, ensuring that insights and solutions are captured at the moment they occur. With structured tagging and hierarchical organization, Dnote encourages users to categorize entries in ways that align with their own thinking rather than forcing a rigid notebook structure. Its search is optimized to handle large collections of notes, allowing users to find relevant information instantly, which makes it especially helpful for developers, engineers, and power users who accumulate practical knowledge over time.
