Viddy is a modern replacement for the traditional watch command, designed for developers and system administrators who need enhanced control over periodic command execution. It executes commands at regular intervals and displays results with powerful features that go far beyond the original watch utility.

Key capabilities include color output for better readability, diff highlighting to spot changes instantly, and a unique time machine mode that lets you rewind through command history like rewinding a video. Navigate to past outputs and jump back to the present with ease.

The tool offers vim-like keybindings for familiar navigation, making it intuitive for terminal users. Additional features include:

Text search functionality to find specific content in outputs
Suspend and restart execution without losing history
Look back through saved command history
View output in a pager for large results
Shell alias support for complex commands
Fully customizable keymappings and colors

Viddy works seamlessly across multiple platforms including macOS, Linux, and Windows, with installation available through Cargo, Homebrew, and various package managers. The tool requires no configuration to get started but offers extensive customization options through a TOML configuration file for those who want to tailor keybindings and behavior to their workflow.
