Alternative to Remote Linux Desktop

Alternatives to Vmware Horizon (Omnissa) offering Linux VDI excellence

Jun, 02, 25

Need a VMware Horizon alternative that brings scalable, cost-effective Linux VDI to your team? When organizations jumped into desktop virtualization in 2020, VMware Horizon quickly became a popular solution. Now, as Omnissa Horizon since 2024, it’s still valued for its solid Windows virtualization, but it falls short for the 47% of IT professionals using Linux-based systems.

Omnissa’s narrow focus on Linux, along with growing licensing costs and system load, is driving teams to look for Linux-native VDI tools that are faster, easier to use, and more budget-friendly. Among the options, ThinLinc stands out for its affordability, strong security, and easy scalability.

High licensing costs

Cost is a key factor in VDI deployment, yet 31% of organizations report sinking massive budgets into operationalization and maintenance. Omnissa, with its expensive licensing tiers and extra fees for additional components like Unified Access Gateway, is part of the problem. 

Last year, it removed perpetual licenses and moved to a subscription-only model with two license types: SaaS (cloud) and Term (on-premises). You can choose between a per named user or concurrent connection model. Pricing varies by edition, though, from $4.67 per user monthly for Horizon Standard to $12.50 Horizon Universal.

While they’ve bundled VMware Vsphere Foundation (VVF) for VDI in all editions, Horizon SaaS licenses (e.g., Horizon Universal, Standard Plus, and Enterprise Plus) require purchasing a core SKU starting at 50 seats. If you need more, you’d have to stack 10-seat add-ons, pushing costs higher as you scale. This makes budgeting and scaling complex.

As an added drawback, unlike ThinLinc, VMware Horizon doesn’t have a free tier to allow teams to experiment with the system before committing to a full deployment.

Windows-first focus

Omnissa Horizon is deeply integrated with Microsoft technologies like Windows Server and Microsoft Azure. Its design and updates clearly prioritize those environments, so while Windows VDI runs smoothly, Linux teams face compatibility problems.

VMware Horizon customers typically complain about:

  • Inconsistent performance with graphics-intensive Linux applications.
  • Occasional challenges with peripheral device redirection and other advanced features.
  • Processor compatibility issues on older hardware missing certain instruction sets.

An Omnissa Community member wrote on the Omnissa forum: “I’ve been asked by my organization to update my VMware Horizon Client to version 2306 or later, or I will soon become unable to connect; I am currently using Horizon Client version 2212.1 on Linux/Ubuntu 22.04.4 LTS (64-bit). However, when I upgrade and try to connect with this new version, the application crashes with an ILLEGAL INSTRUCTION exception. This does not happen using the Windows version of Horizon Client 2306 on the same machine, however!”

Complex deployment & management

Setting VMware Horizon for Linux desktops up involves dealing with multiple components, alongside dedicated hardware for on-premises deployments that pile onto the workload. Getting it all running requires serious VMware training, and it’s a steep learning curve. In fact, many users feel that trying to find answers in their documentation is frustrating.

Vendor lock-in

Omnissa Horizon requires VMware vSphere and vSAN for its infrastructure, limiting flexibility for businesses that want to adopt alternative hypervisors or VDI solutions. Its integration with public clouds like Microsoft Azure and AWS WorkSpaces Core is also tied to hosted vSphere solutions, which can be expensive and geographically restrictive.

Performance overhead

Horizon’s Windows-centric design can hinder Linux performance, causing slowdowns with graphics-heavy apps and high-CPU processes. VMware Horizon’s desktop delivery pipeline, including the Blast Extreme protocol, also adds some overhead. This framework is primarily optimized for Windows environments, which limits the efficiency of features like multi-monitor setups or real-time audio.

Key features to consider in an Omnissa alternative

The key to finding a good VMware alternative is choosing a lightweight tool that balances performance with practicality to boost productivity without unnecessary costs or complexity.

Here are the features you need:

  • Performance & resource efficiency: Look for a Linux-first VDI service that minimizes latency and optimizes CPU use.
  • Scalability: Choose a tool that can support hundreds or thousands of users across sites without performance degradation.
  • Cost-effectiveness: Go for a concurrent user licensing model that slashes costs for shared environments.
  • Security & compliance: Ensure the solution has robust enterprise-grade security, including end-to-end SSH encryption.
  • Ease of deployment & administration: Opt for a tool with simple setup and unified management via web browser or CLI.
