Detailed Introduction
Koillection is a self-hosted, open-source collection manager designed to help you organize and track any kind of physical collection.

It supports multiple database backends (PostgreSQL, MariaDB, MySQL), offers a clean web interface, and has a growing community translating it into over 10 languages. You can try it instantly via Gitpod without installing anything. Ideal for collectors who want full control over their data and privacy.
