OpenFreezer is an open-source laboratory information management system (LIMS) designed to help biological laboratories with reagent tracking and workflow design.

Product history

It's not clear when development first began on OpenFreezer, but a SourceForge project was started by developer Marina Olhovsky on July 18, 2011[2], followed by a file release two days later.[3]. According to the documentation page of the OpenFreezer demo site, the following releases have been made, though when they were released is unknown: 1.1.2, 1.1.3, 1.2, 1.3, 2.0, 3.0, 3.1[4]

The most current release is assumed to be version 3.2, release date unknown.[5] In February 2014, the developers placed a message on the site's front page that a new version was anticipated for "the end of 2014, and [it] will include batch reagent creation."[6] However, that update has not been realized as of August 2020.
