OpenEpi is a free, web-based, open source, operating system-independent series of programs for use in epidemiology, biostatistics, public health, and medicine, providing a number of epidemiologic and statistical tools for summary data.

OpenEpi was developed to perform analyses found in the DOS version of Epi Info modules StatCalc and EpiTable, to improve upon the types of analyses provided by these modules, and to provide a number of tools and calculations not currently available in Epi Info.

Both OpenEpi and Epi Info were developed with the goal of providing tools for low and moderate resource areas of the world.

The initial development of OpenEpi was supported by a grant from the Bill and Melinda Gates Foundation to Emory University.

Planned future development include improvements to existing modules, development of new modules, translation into other languages, and add the ability to cut and paste data and/or read data files.
