Per-user subscriptions, RDS CALs and the end of perpetual licensing have made enterprise remote access more expensive than it needs to be. Here is how the leading Citrix and RDS alternatives actually compare, and which one fits which kind of IT team.
Remote access stopped being a “nice to have” years ago. It is now core infrastructure, and the cost of getting it wrong is measured in both budget and security exposure. The problem is that the two default options most IT leaders inherit, Citrix and Microsoft Remote Desktop Services (RDS), have each become harder to justify on price alone.
Citrix, now operated by Cloud Software Group, discontinued perpetual licensing and pushed customers onto subscription and term contracts. Microsoft RDS still requires per-user or per-device Remote Desktop Client Access Licenses (RDS CALs) on top of Windows Server, and its cloud successor, Azure Virtual Desktop, bills on Azure consumption plus Windows and Microsoft 365 entitlements. Neither is “wrong”, but both reward large, Microsoft-committed or Citrix-committed estates and punish smaller, cost-sensitive teams.
What changed in the remote-access market
Three shifts pushed remote access up the CIO agenda. First, hybrid work made remote desktops a permanent requirement rather than a contingency, so the platform that delivers them became core infrastructure with a multi-year cost attached. Second, the vendors that defined the category changed shape: Citrix moved under Cloud Software Group and retired perpetual licensing, and VMware’s end-user-computing line was spun out into Omnissa in 2024. Third, browser-based remote desktop and RDS delivery via HTML5 matured to the point where installing a native client is now optional. Together these changes mean the “safe” incumbent choice is no longer automatically the cheapest or the simplest, and it is worth re-evaluating the market before every renewal rather than defaulting to the contract you already have.
This guide compares the most credible alternatives for delivering Windows desktops and applications to remote users, scores them on the criteria that matter in production, and explains the trade-offs in plain language.
How we evaluated these platforms
Cruxial CIO is a publication, not a reseller, and we do not accept payment to change a ranking. For this guide we scored each platform against six criteria that consistently decide real deployments:
- Licensing model — subscription, term or perpetual, and whether you are locked into per-seat growth.
- Hosting — can you self-host on your own Windows Server, or are you tied to a specific cloud?
- Microsoft licensing overhead — whether RDS CALs or additional Microsoft entitlements are required.
- Access method — native client, browser-based HTML5, or both.
- Operational complexity — how much specialist skill the platform needs to run.
- Best-fit profile — the size and type of organisation it actually suits.
The best Citrix and RDS alternatives in 2026
1. TSplus — lowest-overhead self-hosted option
TSplus positions itself as a direct, lower-cost alternative to Citrix and Microsoft RDS for publishing Windows desktops and applications. Its main appeal is the licensing model: perpetual, per-server pricing that avoids open-ended per-user subscriptions, plus a browser-based HTML5 access option so end users do not need to install a client. It is self-hosted on your own Windows server, includes a 15-day free trial, and the company reports more than 500,000 companies worldwide. For lean IT teams that want predictable, one-time licensing rather than a growing monthly bill, it is usually the first alternative worth testing.
Best for: mid-market and SMB teams that want self-hosted control and perpetual, per-server licensing.
2. Parallels RAS (Remote Application Server)
Parallels RAS sits closest to “Citrix without the complexity”. It builds on Microsoft RDS to deliver published applications and desktops, but wraps it in a far simpler console and a per-concurrent-user subscription. Teams migrating off Citrix specifically to cut administrative burden tend to shortlist it first. The trade-off is that it is subscription-based and still leans on the underlying Windows RDS stack.
Best for: organisations leaving Citrix that want managed RDS delivery with lighter administration.
3. Microsoft Azure Virtual Desktop (AVD)
If your estate already runs on Microsoft 365 and Azure, AVD is the path of least resistance. It is Microsoft’s own cloud VDI service, billed on Azure compute consumption plus the Windows and Microsoft 365 licensing many enterprises already own. The upside is deep Microsoft integration; the downside is that costs are consumption-based and can be hard to forecast, and you are committing to Azure as your hosting layer.
Best for: Microsoft-committed enterprises already standardised on Azure and Microsoft 365.
4. Omnissa Horizon (formerly VMware Horizon)
The platform formerly known as VMware Horizon now lives under Omnissa, the end-user-computing business spun out of VMware in 2024. Horizon is a mature, full VDI platform aimed at large, regulated enterprises that need granular control over virtual desktops on-premises or in the cloud. It is powerful and battle-tested, but it carries enterprise-grade pricing and operational complexity that smaller teams rarely need.
Best for: large or regulated enterprises that need full VDI and already run VMware/Omnissa infrastructure.
5. Apache Guacamole
Apache Guacamole is an open-source, clientless remote desktop gateway that brokers RDP, VNC and SSH sessions through the browser. The software itself is free, which makes it attractive for budget-constrained or technically strong teams. The catch is that it is a gateway, not a full application-delivery suite: you provide and license the back-end Windows hosts yourself, and you need in-house skill to deploy, secure and maintain it.
Best for: technically capable teams that want a free, browser-based gateway and can self-support it.

“The instinct is to compare these platforms on features, but in 2026 the deciding factor is almost always the licensing curve. A tool that looks cheaper per seat can become the most expensive line item the moment your user count doubles. Model the three-year cost, not the sticker price.”
— David Klein, Editor, Enterprise IT & Infrastructure, Cruxial CIO
How to choose the right alternative
Start from your constraints, not the feature lists. If you are already deep in Azure and Microsoft 365, AVD will usually win on integration even if its bill is harder to predict. If you are escaping Citrix mainly to reduce administrative pain, Parallels RAS is the natural landing spot. If you run a large, regulated VDI estate, Horizon remains the safe enterprise choice.
For the large middle of the market, smaller enterprises and SMBs that simply want to deliver Windows desktops and apps to remote staff without an ever-growing subscription, the decision usually comes down to self-hosted perpetual licensing versus consumption-based cloud. That is where a per-server, perpetual model is most compelling, and why a self-hosted option is worth piloting before you commit to a multi-year cloud contract. As always, run a real proof-of-concept with your actual application set and a representative user load before signing anything.
Whichever direction you lean, validate two things during the trial: how the platform behaves at your true concurrent-user peak, and exactly what you will pay in year three, once any introductory pricing has lapsed and your headcount has grown.
Frequently asked questions
Why are companies moving away from Citrix in 2026?
The main drivers are cost and licensing. Citrix, under Cloud Software Group, ended perpetual licensing and moved customers to subscription and term contracts, and many smaller and mid-sized organisations found the renewal pricing hard to justify for their user counts. They look for alternatives that offer simpler administration or perpetual, per-server licensing instead of open-ended per-seat subscriptions.
Do I still need RDS CALs if I use an alternative?
It depends on the architecture. On-premises Microsoft RDS deployments require Remote Desktop Client Access Licenses (RDS CALs) per user or device, according to Microsoft’s licensing documentation. Some alternatives build on Windows RDS and inherit that requirement, while others use a different per-server or VDI licensing model. Always confirm the exact Microsoft licensing implications with the vendor before you buy.
What is the most cost-effective Citrix alternative for a small team?
For small and mid-sized teams, a self-hosted platform with perpetual, per-server licensing is usually the most predictable on cost, because the price does not scale automatically with every new user. Open-source gateways such as Apache Guacamole can be even cheaper in software terms, but they require in-house technical skill to deploy and secure, which is a real cost of its own.
Can remote users connect without installing software?
Yes. Every platform in this guide offers browser-based HTML5 access in some form, which lets end users reach their desktop or applications from a standard web browser without installing a dedicated client. This is one of the biggest practical improvements over legacy remote-desktop setups and is now considered a baseline expectation rather than a premium feature.
Self-hosted or cloud: which is better for remote access?
Neither is universally better. Self-hosting on your own Windows server gives you control and, with perpetual licensing, predictable long-term cost, which suits teams that want to avoid consumption-based billing. Cloud platforms such as Azure Virtual Desktop reduce infrastructure management but tie your cost to usage and your hosting to a specific provider. Match the model to whether your priority is cost predictability or hands-off operations.
Is open-source Apache Guacamole a real Citrix replacement?
For some teams, yes. Apache Guacamole is a free, browser-based gateway that brokers RDP, VNC and SSH sessions, and for technically strong teams it can replace the access layer of a commercial product. It is not a full application-delivery and management suite, though, so you still provide and license the back-end Windows hosts and handle deployment, scaling and security yourself. Treat the zero software cost as a trade against the engineering time it demands.
