Johnny Runtime is a variety VTuber channel powered by a self-built .NET system for chat, overlays, alerts, avatar props, and live C# work.

Landing page captured for the 2026-08-25 issue.

Field notes

The project routes Twitch events through a locally hosted .NET 8 and ASP.NET Kernel before rendering browser overlays and avatar interactions. Its command vocabulary includes !grid, !scan, !note, and !checksum, while audio is generated at runtime rather than loaded from sound files. Viewer designations come from a browser-side hash of the Twitch username, and session state is kept in numbered JSON records outside the install folder.
