**Dat** (/dæt/[5]) is a [data distribution](/source/Data_distribution) tool with a [version control](/source/Version_control_system) feature for tracking changes and publishing [data sets](/source/Data_sets). It is primarily used for [data-driven science](/source/Data_science), but it can be used to keep track of changes in any data set. As a [distributed revision control](/source/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](/source/John_S._and_James_L._Knight_Foundation)[9] and the [Alfred P. Sloan Foundation](/source/Alfred_P._Sloan_Foundation).[10][2]

Dat is [free software](/source/Free_software) distributed under the terms of the [BSD-3-Clause](/source/BSD_licenses) license.

One of the main implementations is [Beaker](/source/Beaker_(web_browser)), a [web browser](/source/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]
