Rahul Mula

Rahul Mula is an independent developer who focuses on creating lightweight, open-source utilities that solve very specific workflow pain points for presenters, streamers, and educators. His single published Windows application, Keyviz, displays every keystroke and shortcut combination in an unobtrusive on-screen overlay, making it easy for viewers to follow along during live coding sessions, software tutorials, or classroom demonstrations. Because the program is built with modern .NET and released under a permissive license, users can customize the overlay’s position, color, fade delay, and even exclude sensitive typing from view. The tool occupies only a few megabytes of disk space, runs without administrator rights, and consumes minimal CPU, so it can stay active for hours of screen recording without impacting system performance. Although the catalog is presently limited to this one utility, the publisher’s GitHub presence suggests a philosophy of shipping small, focused projects that integrate cleanly with existing Windows workflows rather than pushing expansive suites. Keyviz therefore sits in the same software category as other screen-enhancement aids—such as cursor highlighters, magnifiers, and annotation tools—valued by technical broadcasters and online instructors who need to communicate every click and keystroke to an invisible audience. The application is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources like winget, always install the latest release, and can be queued alongside other programs for convenient batch installation.
