## What it is
Modd is a flexible developer tool that runs commands and manages daemons in response to filesystem changes, configured via a simple modd.conf file. It can replace many functions of task runners like Gulp/Grunt and integrates with devd for in-browser livereload.

## Use cases
- rerun go tests whenever a go file changes
- restart a web server daemon when source files are modified
- replace gulp or grunt for a react frontend build workflow
- trigger livereload in the browser on file changes
- run linters or compilers automatically on save
- manage local development daemons that restart on code changes

## When to choose
- you want a single portable binary with no dependencies for watch-and-rebuild workflows
- you need both one-shot prep commands and long-running daemons managed together
- you want a simple config file you can check into your repo
- you want lightweight livereload during web development

## When to avoid
- you need a full-featured task runner with a large plugin ecosystem
- your project already uses a build tool like webpack or vite with built-in watch mode
- you need complex build orchestration or dependency graphs between tasks
