## What it is
Koillection is a self-hosted web application for managing collections of any kind, such as books, DVDs, stamps, and games. It supports collections, items, custom metadata, tags, wishlists, loan tracking, multi-user access, and a REST API, built with PHP/Symfony on MySQL, PostgreSQL, or MariaDB.

## Use cases
- catalog my book collection online
- self-hosted app to track DVDs and games I own
- manage a stamp collection with custom fields
- keep a wishlist of items to buy
- track who borrowed my items
- organize collectibles with tags and photos
- host a personal inventory manager on my server

## When to choose
- you want full control over metadata fields for any type of collection
- you prefer self-hosting with Docker and your own database
- you need multi-user support, sharing, and loan tracking
- you want a REST API to integrate with other tools

## When to avoid
- you want automatic metadata downloads from online databases like barcode scanning or ISBN lookups out of the box
- you need a mobile-native app rather than a PWA
- you want a hosted service with no server maintenance
