KeyCast v1.0.0
First public release of KeyCast, a clean, minimal keyboard and mouse input overlay for streamers, built with Electron.
Highlights
- Real-time keyboard and mouse overlay served to OBS as a Browser Source
- Configurable layouts: drag to arrange keys, resize caps, multi-select editing
- Combo and Superglide timing caps (Apex Legends Superglide preset included)
- Themes with full color, animation, size, gap, and scale control
- Keys-per-second and per-button click counters
- Multiple profiles for different games
- Single PC and 2PC support (LAN or Tailscale), with a built-in firewall helper
- In-app updates
- Zero data storage: inputs are shown, then immediately discarded
Privacy
KeyCast does not store keystrokes. Input events are rendered on the overlay and discarded immediately. No logs, no history, no telemetry.
Installation
Download the installer below and run it. Windows SmartScreen may warn on first launch because the app is not code-signed; choose More info, then Run anyway. Requires Windows 10 or 11 (64-bit).
