hwatch is a Rust-based alternative to the Unix watch command that repeatedly executes a command and records its output. It provides a TUI with execution history, diff views, JSONL logging, and hooks to run commands when changes occur.

Use cases

• watch command output with history and diffs
• monitor a command and see what changed between runs
• log command execution results as JSONL
• run a hook command when watched output changes
• scroll through past outputs of a repeatedly run command
• view diffs of command output with ANSI colors preserved

When to choose

• you need history and diffing of repeated command output, which plain watch lacks
• you want JSONL logs of command executions
• you need to trigger commands on output changes
• you want a modern, actively maintained watch replacement

When to avoid

• you only need simple periodic command execution and minimal output
• you need remote/system metrics monitoring rather than command output watching
• official distro packaging for your distro is required and not yet available
