In 2005, RexDB was first released for Small Research Groups at Yale University. In 2007, RexDB was used for Simons Simplex Collection. In 2011, in order to benefit the scientific community, Prometheus Research decided to open source the RexDB platform, marking the beginning of the open source initiative. The initiative also accompanied a complete new redesign of all elements of the platform. In 2012, RexDB was released open source under AGLv3 as "RexDB 3.0." In 2013, RexDB was adapted to support disease and procedure specific registries.
