Data Crow is a completely free Open Source product, developed by myself (Robert Jan van der Waals). If you like the product and you want to support my endeavour in creating the best collection management product out there then you should consider becoming a patron.

Data Crow Principles


Data Crow’s concept is simple; you are in charge of the product. The focus of Data Crow has always been… customizability. Create new collection modules, add/rename/remove fields, change the layout, the look and feel, etcetera.

Protecting your Privacy

Have you seen all the fancy cloud based products? Low prices, great benefits? But where is your data? Do you truly own your data… completely? Data Crow stores the data on your computer(s), it’s your data. No one will have access to your data, unless you decide otherwise. Privacy is scarce these days.

One Stop Shop

The ultimate collection manager. Everything in once place; it makes life easier. You register all your collections in one product and you always know where and how to find the information… in that one product.

Free to use and Open Source

Data Crow will always be free to use and its source code will always be available.
