Fully isolated, high-performance dev labs on a single Proxmox host.

Most security incidents don't start in production.
They start in "just a dev box":

• A VM in the cloud with a public IP and SSH open to the Internet
• Test environments for different clients accidentally seeing each other
• "Temporary" instances that nobody remembers to shut down
• Underpowered instances that slow everyone down, but nobody has time to fix

Developers are not malicious. They simply don't have the guardrails to safely operate infrastructure while they're trying to ship features.

When dev environments are treated as disposable, they quietly turn into:

• A growing attack surface that nobody is really watching
• Unpredictable, slowly increasing cloud bills
• Shadow infrastructure that security and IT teams don't fully control

Result: a mess that leads to the classic conclusion:
"Turns out on-prem was safer after all."

MSL Setup takes the opposite approach:

• Run everything on your own hardware (a single Proxmox host is enough)
• Give each project its own fully isolated Layer-2 network and VPN entry
• Make it easy to spin labs up and down without exposing your main LAN

Instead of "temporary" cloud instances, you get a permanent, isolated dev lab that behaves predictably and is designed not to leak into the rest of your network.

MSL Setup is for teams and freelancers who:

• Need realistic, high-performance dev and test environments
• Must keep client projects strictly separated from each other
• Want to move fast without turning every test VM into a production risk

That's why this project exists: to give you a way to move fast in dev — without turning every environment into a security or compliance incident waiting to happen.

Yes. MSL Setup Basic is publicly available on GitHub. It’s a step-by-step, manual build guide (not the one-click automation). MSL Setup Basic: https://github.com/zelogx/proxmox-msl-setup-basic

Personal License is intended for individual use (e.g., homelab users or freelancers) to build and manage their own isolated lab environment using the automation workflow. Enterprise License is intended for organizations deploying isolated development environments for teams and business use cases, with terms suitable for corporate adoption.

MSL Setup Pro is licensed per host. If you want to use it on multiple physical hosts, please purchase a license for each host.

The default design prioritizes performance and simplicity by leveraging the Proxmox host and its kernel directly, rather than introducing additional network appliances such as VLAN-based firewalls, pfSense, or OPNsense. That said, you’re free to integrate them into your own environment if your requirements call for it. You’re free to integrate them in your own environment if you want, but they’re not required by the standard setup.

Support options depend on the license and availability. For Basic users, support is typically community-based (GitHub issues/discussions). For Pro/Enterprise, We currently do not offer formal support plans. We may offer consulting services on a case-by-case basis. We may be able to discuss individual consulting or support arrangements depending on availability.

No. By default, MSL Setup routes VPN traffic only to the isolated lab networks. Your users' Internet-bound traffic keeps using their own normal gateway, so the VPN server is an entry point to the lab – not a full-tunnel Internet proxy.

It's a third-party project by Zelogx that builds on top of Proxmox features (e.g., SDN and firewall rules) to provide a structured, repeatable lab setup workflow.

Production use is possible, but typically requires additional design considerations beyond the default scope of MSL Setup. The current implementation is primarily designed for a single Proxmox host.Production deployments may require additional planning around reliability, scalability, and SLA requirements, such as cluster configurations or expansion strategies.
