Many enthusiasts working in the tech sector as system admins or similar roles create and maintain a homelab technology sandpit. A homelab is a personal computing environment that mimics enterprise-level setups, allowing individuals to explore various technologies, software and configurations in a controlled setting. They use this homelab to learn new technologies, train for certification exams or, truthfully, just for fun!
Creating a homelab today is relatively simple due to the availability of virtual machines and other virtualized software components that can mimic almost every piece of hardware imaginable. The advent of cloud platforms has also made it easy and inexpensive to expand these homelab environments to the cloud to create hybrid cloud setups. This is beneficial from a learning point of view as many enterprise computing platforms have infrastructure that spans on-premise and cloud platforms. Hybrid is the new normal!
However, as homelab setups grow in complexity, the need for load balancers to provide IT resource management becomes more apparent. In addition to optimizing performance and distributing workloads effectively, having similar load balancers used in the jobs that homelab users have or might move to is highly beneficial.
For users looking to take their homelab to the next level, FreeLoadBalancer.com is an ideal option for bringing your enterprise load-balancing capabilities to homelab environments. You can deliver a resilient application experience on over 100,000 global deployments while using the same core LoadMaster product and code.
The freely downloadable load balancer available via FreeLoadBalancer.com is a member of the award-winning Progress Kemp LoadMaster family. It runs the same code base as its commercial siblings and can be used freely, even in production environments where the throughput requirements do not exceed 20 Mbps of Layer 7 traffic and the services being load balanced do not directly generate revenue. This makes it a perfect choice for homelabs used for DevSecOps testing environments, technical training or any other non-commercial deployment needs that you may have.
As Free LoadMaster is a peer member of the LoadMaster family of products, almost everything true for the commercial editions of LoadMaster also applies to Free. The 'almost' in the previous sentence highlights that there are some restrictions applied. The limits don't change the code in Free LoadMaster or how you configure it. Instead, they target specific capabilities and functionality that are more applicable to larger deployments requiring a commercial license. The restrictions on Free LoadMaster are:
When you purchase a commercial license for LoadMaster and apply it to a Free LoadMaster instance, these restrictions get removed. There is no need to remove your Free LoadMaster deployment and reconfigure a new commercial LoadMaster instance from scratch. This is unlikely to be something that a homelab user will need to do, but the option is available if required.
What FreeLoadBalancer.com delivers for homelab environments is its ability to offer enterprise-grade features at no cost. The available throughput and TLS transactions per second are more than sufficient for most homelab setups. Additionally, its compatibility with various virtualization platforms makes it versatile for different homelab configurations. Read the FreeLoadBalancer.com features page to find out more.
Installing a free load balancer from FreeLoadBalancer.com is straightforward. The steps to follow are:
The process of installing the free load balancer in your homelab network is outlined and explained in this excellent 42-minute video from NetworkChuck.
The free load balancer is usable with multiple hypervisors, and you can find documentation for installing and configuring it for VMware, Microsoft Hyper-V, KVM, Nutanix, Oracle VirtualBox and XEN on the LoadMaster support pages.
Many homelab deployments also include various services such as Plex media servers, network-attached storage, low-traffic websites and more that often need to be accessed remotely. After deploying a load balancer such as the LoadMaster one available from FreeLoadBalancer.com, these services can be accessed securely over the Internet via a single exposed IP Address and port, with the load balancer doing internal request routing as a reverse proxy based on the URL. Additionally, you can use it to:
Basically, the main practical applications of load balancers in homelab setups are to expose internal services to the Internet securely and to provide a sand pit that is a microcosm of how load balancers get deployed, configured and used in production environments—enabling technical users to learn how to setup load balancers in an environment that is not mission critical. It also allows them to make mistakes away from the gaze of their peers or colleagues.
One of the strengths of FreeLoadBalancer.com is that it shares the user-friendly interface found in the commercial LoadMaster editions. This makes it accessible for those new to load-balancing concepts and also means that the skills learned will be transferable for use in the job market.
FreeLoadBalancer.com has an intuitive web-based management interface that provides straightforward navigation and visualizations of load-balancing configuration and any virtual services. Virtual services map incoming access requests (for example, to your Plex server) to the actual resources on the home network.
Key parts of the free LoadMaster interface include:
For homelab users who are comfortable with scripting, the free load balancer shares LoadMaster's API access and control options. You can use a RESTful API or Microsoft PowerShell to configure your deployment.
Taken together, the web console interface and the scripting options allow homelab users to set up, configure and control their free load balancer deployment using any combination of methods they are comfortable with. You can also use this controlled and non-critical deployment to learn how to use any of the configuration methods they are unfamiliar with, such as PowerShell, which is increasingly required in the technical systems admin job market.
FreeLoadBalancer.com integrates well with technologies and services often found in homelab setups. We've already mentioned, and Chuck goes into them in the video above, Plex servers, network storage and websites. The free load balancer is ideal for use with (and for learning more about) common technology stacks used across the technology landscape. Examples include:
The bottom line—if you can install a service in your homelab and publish it via an IP address, then the FreeLoadBalancer.com load balancer can help you publish it internally and on the Internet in a secure and easily managed way.
While it may not be front and center to a homelab deployment, the use of a free load balancer in this setting will bring both performance enhancements and enable greater scalability. Using the product available from FreeLoadBalancer.com boosts homelab performance by providing the following:
In terms of scalability, while the free version has the limitations outlined previously, it does provide ample room for growth in most homelab scenarios. If your homelab expands, you can easily add more instances to your load-balancing pool, allowing you to scale what they are controlling. In extreme cases where you outgrow the restrictions that the free load balancer has, you can purchase and apply a commercial LoadMaster license to your load balancers and the restrictions get removed. You won't have to restart your configuration from scratch. This is another benefit of Free LoadBalancer running the same core code as the commercial LoadMaster.
Cybersecurity is a paramount concern for every IT system on the Internet. As this is something that many homelab setups do, then security has to be a consideration. Load balancers play a significant role in the multi-layered security strategies that most organizations now use. Gone are the days when a single security solution delivered the protections needed. Now many security solutions are necessary at appropriate points across the IT infrastructure. Examples include network firewalls, intrusion detection systems, network detection and response (NDR) solutions, Security Event and Information (SEIM) systems, Identity and Authentication Management (IAM), Zero Trust Network Access (ZTNA) and web application firewalls (WAFs).
FreeLoadBalancer.com offers several features to enhance your environment's security:
A WAF augments the security protection provided by other security solutions but does not replace traditional network firewalls. WAFs operate at various layers of the network stack, including the application, transport and network layers. The free load balancer includes a WAF engine that allows you to deploy custom rules to protect services that are sitting behind the load balancer. The OWASP Core Ruleset comprises a common set of rules that the WAF can use. This ruleset detects and protects against the threats in the OWASP Top 10, plus many others.
When you deploy the free load balancer in your homelab setup, you should adopt these best practices:
A quick search for Kemp LoadMaster Free Reviews will highlight that many people have downloaded and deployed the free edition of LoadMaster from FreeLoadbalancer.com. Plus, as emphasized previously, the free edition has the same code as the commercial version, so reviews for all editions of LoadMaster are applicable to the free version (but bear in mind the restrictions outlined above). Users often praise the ease of use, robust feature set and reliability of the LoadMaster range across both small-scale and enterprise environments.
You can read reviews of LoadMaster at all the leading review sites. For example:
Compared to other load-balancing solutions for homelabs, FreeLoadBalancer.com offers several advantages:

As the Free Load Balancer shares the same unified code base and development roadmap as the commercial LoadMaster editions, then the free version will receive and benefit from future additions and changes to LoadMaster. As the adage goes, "It is difficult to make predictions, especially about the future," but let's speculate on how the load-balancing sector might change over the next few years. If these changes make it into the commercial version of LoadMaster, then they will likely also appear in complete or limited form in the free version when used in homelab deployments.
The uptake and use of web-based applications will only accelerate in the foreseeable future. As a result, the need for load balancers to deliver uptime and performance will also increase. One key trend in load balancing will likely be an increased adoption of machine learning (ML) technologies. By analyzing large amounts of data on application performance, user behavior and infrastructure health, load balancers and supporting management infrastructure solutions will be able to optimize traffic distribution proactively, predict potential issues and provide actionable insights to administrators.
Application security will also see advancements on load balancers. As cyber threats evolve and become more sophisticated, load balancers will gain additional security features to provide even more comprehensive protection against emerging threats. This may include enhancements to WAF capabilities, advanced bot management and further integration with leading security information and event management (SIEM) solutions.
Lastly, load balancing will likely see a growth in the importance of automation and DevSecOps workflow integration in the future. The evolution of more robust APIs and integrations with popular infrastructure-as-code tools will enable organizations to embed load-balancing configurations into their continuous integration and deployment pipelines. This will allow for faster, more reliable application deployments and updates while minimizing the risk of human error.
