OpenLava is an open source workload job scheduling software for a cluster of computers. OpenLava was derived from an early version of Platform LSF. Its configuration file syntax, API, and CLI have been kept unchanged. Therefore, OpenLava is mostly compatible with Platform LSF.

In 2007, Platform Computing (now part of IBM) released Platform Lava 1.0, which is a simplified version of Platform LSF 4.2 code, licensed under GNU General Public License v2. Platform Lava had no additional releases after v1.0 and was discontinued in 2011.
In 2011, former Platform Computing employee David Bigagli created OpenLava 1.0 by forking code from Platform Lava.
In January 2012, OpenLava 2.0 was released with feature enhancements and bug fixes.
In November 2013, OpenLava 2.2 was released.
In April 2015, OpenLava 3.0 was released.
In November 2015, OpenLava 3.1 was released.
In February 2016, OpenLava 3.2 was released.
In May 2016, OpenLava 3.3 was released.
In October 2016, OpenLava 4.0 was released.
In 2014, a number of former Platform Computing employees founded Teraproc Inc., which contributes development and provides commercial support for OpenLava. Commercially supported OpenLava contains add-on features than the community based OpenLava project.. Commercial support is no longer available - see below.
In October 2016, IBM filed a lawsuit alleging copyright infringement and trade secrets misappropriation against Teraproc. The complaint accused some of the company's founders of taking “confidential and proprietary source code" for IBM's Spectrum LSF product when they left, which was then used as the basis of the competitive product OpenLava. David Bigagli, the TeraProc employee who started the OpenLava project, posted a notice on GitHub announcing that downloads for OpenLava had been disabled because of a DMCA takedown notice sent by IBM's lawyers.
Bigagli later announced that the source code for OpenLava 3.0 and 4.0 would be taken down, while the source code of 2.2 would be restored in order to regain the GitHub repository and the openlava.org website, while claiming that the DMCA claim is fraudulent.
On September 18 2018, the US Courts found in favor of IBM and issued a permanent injunction against Teraproc and its agents.
