The collection manager that belongs to you.
Catalog comics, books, vinyl, trading cards, wine, watches, games, anything you collect. Own your data. Self-host or use the cloud.

Any collection
One tool for every hobby. Collect anything, and the app adapts to it.
Your data
Open schema, one click export, no lock-in. Keep your catalog forever.
Open source
The whole source, in the open. Auditable, forkable, community driven.
Organize everything
Structure that bends to how you collect.
Unlimited collections, nested categories, tags, locations, and conditions, all on beautiful item pages that make your catalog feel like a museum, not a spreadsheet.
Unlimited collections
Split what you own however you like. No tier gates the structure.
Nested categories
Marvel, then Spider-Man, then 1990s. Structure as deep as you need.
Tags
Cross-cut your catalog with flexible, colour coded labels.
Nested locations
Room, shelf, box. Always know where a piece lives.
Conditions
Grade every item on the scale that fits your hobby.
Beautiful item pages
Rich pages that make a catalog feel like a museum.
Adapt to your hobby
Every collection is different. Your fields should be too.
Define completely custom item types with your own fields, sections, and metadata. A book isn't a bottle of wine, so don't force them into the same form.

Track physical copies
One catalog entry. Every copy you own.
Some things you own more than once. Track each copy independently: purchase date, price paid, estimated value, condition, location, and provenance.
One app for every collection.
Not just books. Not just comics. Not just wine. If you collect it, KolleK catalogs it.

Privacy
Private by default. Not by policy.
Your catalog is nobody's business but yours. No cookie banners to click away, because there's nothing behind them.
Encrypted at rest
Every catalog, item, and uploaded image is encrypted at rest. Even on our cloud, your data sits behind encryption you don't have to think about.
Zero tracking
No analytics, no trackers, no third-party pixels, no telemetry phoning home. We don't watch what you collect, and there's nothing to sell because we never collect it.
One price. No subscriptions.
Self-host it for free with no limits at all, or try the managed cloud with ten items free and unlock it with one payment. No monthly bill, no renewal, ever. Your data is portable either way.

KolleK ships as a single container. One docker run and you have the full application on your own hardware, with your data on a volume you control.
Self-hosting is free forever under the MIT License, with no item limit at all. On the managed cloud an account holds ten items for free, and a single payment unlocks it for good. There is no subscription either way.
You do. There is no proprietary format and no lock-in. Everything is stored in an open schema you can inspect, back up, and take with you.
Not yet, and we would rather say so here. Collection type definitions export and import as JSON, and open loans download as CSV. If you self-host, a backup of the database and the storage volume holds everything.
Yes. A documented REST API covers every collection, item, and custom field, so you can script imports, sync tools, or build your own front end.
Absolutely, that is the point of MIT. Open an issue, send a pull request, or fork it entirely. The roadmap is public and community driven.
Your collection deserves better than spreadsheets.
Open source, MIT licensed, and yours to keep. Start in the cloud or self-host in a single command.
