A Load Balancer for Any Workload

Kemp, Inc. was founded in 2000 in Bethpage, New York and operates in the application delivery controller industry. The company builds load balancing products which balances user traffic between multiple application servers in a physical, virtual or cloud environment.

In 2010, Kemp opened a European headquarters in Limerick, Ireland Edison Ventures, Kennet Partners and ORIX Venture Finance invested $16 million into the company for research and development, sales and marketing in early 2012. In April 2014, Kemp announced a further investment in its Limerick Operations to expand from 30 positions to 80. Kemp was recognized as a Visionary in the 2015 Gartner Magic Quadrant for Application Delivery controllers and again in 2016.

In 2019, Kemp was acquired by private equity firm Mill Point Capital.

Kemp is a software company that develops load balancing and application delivery software built on a bespoke Linux operating system which is sold under the LoadMaster brand. As of 2019, there were over 100,000 deployments of LoadMaster globally for customers that need high availability, scalability, security and visibility for their applications. This enables customers to scale their operations by delivering applications in a highly available manner with layer 4 to 7 load balancing, enhanced performance, and greater security. LoadMaster is available as a hardware appliance as well as a software-based load balancer that is available as a virtualized appliance and in the cloud including Microsoft Azure, Amazon AWS, and other private clouds.




Kemp is offering the Free LoadMaster to help small companies and developers by providing them with a robust and proven load balancing option. As their load balancing needs grow and expand, they will be able to upgrade to a commercial version in the future, since they will already be comfortable with and knowledgeable about the LoadMaster.

The availability of a proven free load balancer from a well-established company will enable many start-ups and QA/Dev teams to focus on the task at hand. They will no longer have to worry about addressing the trade-off between cost, quality and upgradeability associated with some open source and application-embedded load balancing solutions.

The Kemp Load Balancer is also great for existing Kemp customers who wish to replicate their production environment for UAT purposes. While there are some limiting differences between the Free LoadMaster and commercial versions, this community supported, lower performance model provides all of the same core functionality that is included in our commercial LoadMasters.
