gallery-dl

gallery-dl is a URL-driven downloader for pulling media and metadata from a large catalog of supported sites, including galleries, creator pages, boards, posts, and collections. It is built around extractor modules and deep configuration rather than a human-first interactive flow.

• Download images, videos, and attached metadata from supported gallery, creator, forum, and social media URLs.
• Queue URLs from stdin or files, filter by ranges, dates, tags, or custom expressions, and keep state with archives and cache files.
• Extract direct file URLs or structured metadata without downloading, then feed the results into other shell tools.

• Non-interactive flags, input-file support, and config-driven authentication make it workable in unattended batch jobs.
• Real structured output exists via -j/--dump-json, -J/--resolve-json, and optional JSON Lines mode for downstream parsing.
• Fit is mixed by site-specific extractor reliability: protected sources often need cookies or browser state, and upstream site changes can break workflows.

• Some video and conversion flows depend on extra tools such as yt-dlp, ffmpeg, or mkvmerge.
• Support is extractor-by-extractor, so coverage and stability vary by site.
