Koillection

Koillection is a self-hosted collection manager designed to catalog and track collections of many kinds, especially physical items such as books, games, DVDs, and stamps. It focuses on flexible data modeling rather than built-in metadata providers, so you can tailor item details to your needs.

Key Features

• Create and manage multiple collections with customizable item data
• Add and edit metadata manually to fit any collection type
• Optional HTML scraping to help populate metadata from external pages
• Web-based interface built for personal or family use
• API-based architecture suitable for integrations and automation

Use Cases

• Maintain a home inventory of books, board games, or movies
• Track collectibles (cards, stamps, figurines) with photos and detailed attributes
• Build a custom catalog for niche collections where standard metadata sources don’t apply

Limitations and Considerations

• No built-in metadata provider downloads; metadata is manual or scraper-based
• Updates may include database migrations, so regular database backups are important

Koillection is a solid choice when you need a general-purpose, customizable collection tracker rather than a media-specific catalog. Its flexibility makes it suitable for both simple inventories and detailed collectible databases.
