VMware ESXi Free Is Back – But Should Edinburgh SMEs Trust It?
In January 2024, Broadcom eliminated the free vSphere Hypervisor download that hundreds of thousands of small businesses had relied on for years. The backlash was loud and immediate. Edinburgh IT professionals who’d built careers on ESXi watched the free licence disappear overnight, with no migration path offered and no alternative provided (Broadcom).
Then – under pressure from community anger and the very real threat of mass migration to Proxmox – Broadcom brought back a form of free ESXi (Gartner Magic Quadrant for Cloud Infrastructure).
This feels like good news. It might not be.
Here’s the honest assessment of what free ESXi currently offers, what the conditions are, and why Edinburgh SMEs should think carefully before building production infrastructure on it (The Register).
TL;DR: Free ESXi is available again in a restricted form – permitted for personal and educational use but not for commercial production workloads without explicit authorisation. Even if it were fully free for commercial use, the lesson of 2024 is clear: Broadcom can remove free VMware products whenever it’s commercially convenient, and they will. Edinburgh businesses that want a truly free, production-grade hypervisor should be looking at Proxmox VE, which has a genuine open-source foundation rather than a vendor-controlled free tier that can be revoked overnight.
What Happened to Free ESXi in 2024
The history matters for understanding why the “it’s back” announcement deserves scrutiny.
Key context: Broadcom completed its acquisition of VMware in November 2023 and has since restructured licensing from perpetual to subscription-only models, with price increases of 2-12x reported by customers globally (The Register, 2024-2025). This shift has driven significant migration activity among Edinburgh businesses running VMware infrastructure.
VMware offered a free vSphere Hypervisor (commonly called ESXi Free) for years. It had limitations – no vCenter management, no HA, no vMotion – but it ran real workloads reliably and was genuinely free for commercial use. Thousands of Edinburgh SMEs, charities, schools, and small businesses ran production systems on it.
Broadcom closed the VMware acquisition in November 2023. By January 2024, the free vSphere Hypervisor download had been removed from VMware’s website without announcement. Businesses with running free-licensed ESXi installations found they could still operate their existing deployments, but couldn’t download fresh ISO images, receive security patches through normal channels, or stand up new installations without a paid licence.
The response was swift. Proxmox download numbers spiked. GitHub repositories hosting old ESXi ISOs appeared and were subsequently taken down. Forum threads across the Edinburgh IT community and r/sysadmin documented the same story: years of trusted infrastructure, deleted with no notice.
What this tells us about Broadcom’s intent: The decision to eliminate free ESXi without transition support wasn’t a mistake or an oversight – it was a deliberate business move. Broadcom acquired VMware to extract maximum value from the installed base and premium enterprise accounts. Free tiers don’t contribute to that goal. When the backlash was commercially inconvenient, they partially reversed. This is vendor behaviour you should factor into your long-term infrastructure planning.
What Free ESXi Looks Like Now
Broadcom reintroduced a free VMware Hypervisor download under the following terms as of 2025:
Permitted use: Personal use, home lab, educational and non-commercial evaluation
Not included:
- Commercial production use without Broadcom’s explicit authorisation (the terms are ambiguous, but the conservative reading is that running client workloads – i.e., your Edinburgh business’s production VMs – requires a paid licence)
- Access to vCenter Server (you’re managing hosts individually with the local web client)
- VMware HA, vMotion, or DRS (no live migration, no automatic failover)
- Official support – zero – any issues are community-supported
- Guaranteed access to future security patches and updates through normal channels
What you do get:
- A functional Type-1 hypervisor on commodity x86 hardware
- The ESXi web client for VM management
- NFS and iSCSI storage connectivity
- Up to 8 vCPUs per VM, 6TB RAM per host (the old free licence was capped lower)
For a home lab or a technical evaluation environment, this is genuinely useful. For production Edinburgh business workloads – payroll, CRM, accounting, document management – the terms ambiguity and support gap are significant risks.
The Case For Using Free ESXi (When It Makes Sense)
Be fair to both sides. Free ESXi in its current form is genuinely appropriate for:
Home labs and personal development: IT professionals maintaining their skills on VMware infrastructure, developers testing deployment pipelines, students working toward VMware certifications. No commercial use, no problem.
Technical evaluation: An Edinburgh business evaluating whether to stay on VMware wants to test current ESXi behaviour before committing to a migration direction. Running a short-term evaluation on free ESXi is reasonable.
Very small, low-criticality deployments: A single Edinburgh SME with one physical host, running non-critical internal services (a print server, an intranet), where the “production” consequence of a failure is a minor inconvenience rather than a business-critical outage. If you can tolerate the host going down for 48 hours, the absence of HA is less important.
Our position at Virtually Pro: We don’t recommend free ESXi for any client where the VM workloads are business-critical. The licensing ambiguity alone creates risk. If Broadcom decides to close the free tier again in 2027, businesses built on it face the same emergency we saw in 2024. We’ve guided every Edinburgh client with production workloads toward either a paid VMware subscription (if the economics work) or Proxmox VE.
The Case Against: Why the 2024 Lesson Still Applies
The fundamental problem isn’t the current terms – it’s the precedent.
Broadcom demonstrated in January 2024 that it will eliminate a free product that thousands of businesses depend on, with no migration path and no notice. The reinstatement of free ESXi happened under community pressure. It is not a policy commitment. There is no contractual guarantee that free ESXi will remain available, remain free for commercial use, or continue to receive security patches.
Compare this to Proxmox VE:
- Proxmox VE is Apache-licensed open source. The code is public, forkable, and not controlled by a single vendor.
- The Proxmox company provides commercial support subscriptions, but the software itself is not dependent on that subscription to function.
- If Proxmox GmbH ceased trading tomorrow, the open-source community could fork and maintain the codebase. This is not true of ESXi.
Proxmox VE: The Alternative That Didn’t Disappear
Proxmox VE gained thousands of Edinburgh conversions in 2024 precisely because it couldn’t be taken away overnight. The code is public. HA clustering, live migration (KVM-based), storage replication, and backup are all included in the free community version. There is no “free tier” – it’s genuinely open source.
The trade-offs are real:
- Proxmox’s UI is good but not as polished as vSphere’s
- VMware ecosystem tools (vCenter plugins, NSX, Horizon) don’t work on Proxmox
- Linux comfort is important for troubleshooting – Proxmox is a Debian-based system
For an Edinburgh IT team experienced with VMware, the learning curve is typically 2-4 weeks to get comfortable. For the price (zero licensing) and the reliability (no Broadcom interference), most Edinburgh businesses we’ve worked with consider the switch worthwhile.
How to migrate from VMware ESXi to Proxmox VE
VMware migration pitfalls guide
What Edinburgh SMEs Should Actually Do
If you’re currently running free ESXi:
Review what you’re running on it. If the workloads are genuinely non-critical and you understand the licensing ambiguity, you may be fine staying put for now. But document a migration plan.
Don’t build new production infrastructure on free ESXi. Any new virtualisation platform for a real Edinburgh business workload should be either a paid VMware subscription (if the economics make sense) or Proxmox VE. Building on free ESXi today means repeating 2024’s situation in 2027 or 2028.
Use the current window to migrate. Proxmox VE migration from ESXi is well-documented. The tools are mature. If you’re on free ESXi now, the cost of migrating to Proxmox is a few days of downtime planning – vastly better than scrambling under a forced migration when Broadcom closes the free tier again.
If you’re not sure which direction to go, that’s exactly what we help Edinburgh businesses figure out. No vendor stake in the outcome – just an honest read of your specific infrastructure.

Frequently Asked Questions
Is free ESXi legal for Edinburgh business use in 2026?
Broadcom’s current free ESXi terms explicitly allow personal and educational use. Commercial production use falls into a grey area – the terms say “personal use” without defining what distinguishes personal from commercial. Conservative legal advice for Edinburgh businesses is to treat free ESXi as not licensed for production commercial workloads. If in doubt, seek legal advice on the EULA terms or use Proxmox VE.
Does free ESXi receive security updates?
Broadcom provides updates through the standard VMware patch mechanism only for paid subscribers. Free ESXi users are directed to community channels. During 2024, there were multiple high-severity ESXi vulnerabilities patched for paid customers that were not easily accessible to free licence holders. For any Edinburgh business handling personal data under UK GDPR, running unpatched hypervisor software carries compliance risk.
Can I run a Proxmox and free ESXi cluster together?
No. Proxmox and ESXi use incompatible hypervisor architectures. They cannot form a shared cluster or live-migrate VMs between them. If you’re evaluating Proxmox, run it on a separate physical host. Use the ESXi-to-Proxmox migration process to move VMs across when you’re ready.
How much does Proxmox enterprise support cost?
Proxmox enterprise subscriptions (which provide access to the enterprise update repository and Proxmox’s commercial support team) start at approximately €110/year per CPU socket. This is optional – the community edition is fully functional without it. Most Edinburgh SMEs use community Proxmox for several months before deciding whether enterprise support is warranted.
