Dat (/dæt/[5]) is a data distribution tool with a version control feature for tracking changes and publishing data sets. It is primarily used for data-driven science, but it can be used to keep track of changes in any data set. As a distributed revision control system it is aimed at speed, simplicity, security, and support for distributed, non-linear workflows.[6]

Dat was created by Max Ogden in 2013 to standardize the way data analysts collaborate on the changes they make to data sets.[7] It is developed through funding support from Code for Science,[8] the John S. and James L. Knight Foundation[9] and the Alfred P. Sloan Foundation.[10][2]

Dat is free software distributed under the terms of the BSD-3-Clause license.

One of the main implementations is Beaker, a web browser that seamlessly handles dat:// URLs and allows building and seeding Dat websites.[11] Homebase is a server-side permanent seeding tool for Dat.[12]
