## What it is
Grabber is a highly customizable imageboard/booru browser and mass downloader that can fetch thousands of images from multiple booru sources at once. It features powerful token-based filename and directory templating, tag search with post-filtering, blacklists, favorites, and a command-line interface.

## Use cases
- bulk download images from danbooru or gelbooru
- organize downloaded images into folders by artist and character
- search multiple boorus at once and deduplicate results
- download images by md5 or id
- monitor favorite tags for new images
- push downloaded images into a local booru like szurubooru
- script image downloads from the command line

## When to choose
- you need to mass-download images from booru/imageboard sites with custom naming and directory structures
- you want a GUI booru browser with tag autocomplete, blacklists, and multi-source search
- you need cross-platform support including Windows, macOS, Linux, and Android
- you want to integrate downloads with a self-hosted booru or database

## When to avoid
- you need a general-purpose web scraper for non-booru sites
- you only want a lightweight single-image downloader without search features
- you need a headless server-side scraping service rather than a desktop app
