history

Project history and usage

kbt is a Rust terminal keyboard tester whose upstream README expands the name as keyboard tester and frames it as a terminal alternative to online keyboard-test pages.

Project history

The repository was created in March 2023 and published release builds during 2023, with 1.0.0 appearing on July 23, 2023 and 2.1.0 on January 6, 2024. The README presents the project as a deliberately small terminal utility motivated by frustration with semi-broken web-based keyboard testers.

Adoption history

The package reached CLI users through several package-manager channels recorded in the batch input, including Homebrew, Nix, Arch Linux, and Cargo installation.

How it is used

kbt is run as an interactive terminal UI for checking keyboard input and layouts. The README notes Linux, macOS, and Windows support, a Wayland limitation, and a macOS first-run Accessibility permission requirement.

Why package nerds care

For package collectors, kbt is a tidy example of the post-ratatui Rust TUI wave: a small hardware-adjacent diagnostic tool that moved from Cargo-style distribution into mainstream Unix package managers.
