KLEKSI, the collection management system for museums

KLEKSI is intended for museums with small to large collections. Museums hold an enormous diversity of collections, from watercolors to prehistoric skeletons, from pottery shards to classic cars. They keep these collections for a reason: museums document, digitize and make them accessible to the public. They ensure that future generations can also form an image of the past on the basis of these objects.

Documenting and digitizing objects as well as possible for posterity is of great importance. KLEKSI helps museums and makes managing collections very easy.

Manage different collections with only 1 system

With KLEKSI you can create and manage multiple collections. You can configure each collection yourself with other input fields, you decide how you want to document and archive your collections.

KLEKSI makes your collection, exhibition and museum easier to find

The frontend, the search function and filter option for visitors are installed on your own (existing) domain name.
KLEKSI is SEO technically optimized so that your collection is perfectly indexed by search engines.
The more visitors discover your collection, the more visitors you will eventually attract to your exhibition or museums.
