OpenEMR was originally developed by Synitech and version 1.0 was released in June 2001 as MP Pro (MedicalPractice Professional).[47] Much of the code was then reworked to comply with the Health Insurance Portability and Accountability Act (HIPAA) and to improve security, and the product was reintroduced as OpenEMR version 1.3 a year later, in July 2002.[48] On 13 August 2002 OpenEMR was released to the public under the GNU General Public License (GPL), i.e. it became a free and open-source project and was registered on SourceForge.[49][failed verification] The project evolved through version 2.0 and the Pennington Firm (Pennfirm) took over as its primary maintainer in 2003.[47] Walt Pennington transferred the OpenEMR software repository to SourceForge in March 2005.[50] Mr. Pennington also established Rod Roark, Andres Paglayan and James Perry, Jr. as administrators of the project.[47] Walt Pennington, Andres Paglayan and James Perry eventually took other directions and were replaced by Brady Miller in August 2009.[51] Robert Down became an administrator of the project in March 2017.[51] Matthew Vita was an administrator of the project from July 2017 until February 2020.[51] Jerry Padgett became an administrator of the project in June 2019.[51] Stephen Waite became an administrator of the project in February 2020.[51] Stephen Nielson became an administrator of the project in January 2022. Asher Densmore-Lynn became an administrator of the project in January 2024. So at this time Rod Roark, Brady Miller, Robert Down, Jerry Padgett, Stephen Waite, Stephen Nielson, and Asher Densmore-Lynn are the project's co-administrators.[51]

In 2018 Project Insecurity found almost 30 security flaws in the system, which were all responsibly addressed.[52]
