Transparency is a feature.
Published prices. Readable source code. Built for AI agents. realvirtual is open by design — so your digital twin stays yours: auditable, portable, and something you can build your own business on.
Openness at realvirtual is a deliberate design decision, not a slogan: published prices, readable source, open interfaces. It protects your investment for the decade you will rely on this infrastructure — and it lets you build your own offering on top, on your own terms. Increasingly, that is exactly what engineers expect.

What openness looks like in practice
The concrete difference an open approach makes.
AI moves fast. Suppliers change hands.
What happens to your digital twin if a closed-source vendor is acquired, quietly winds down development, or doubles the price at your next renewal? With realvirtual the source is yours — to run, adapt, and keep on your own hardware, for as long as the machine lives. That is the difference between renting your foundation and owning it.
Questions about open
Why give away source code and publish prices?
Because trust compounds. Engineers adopt what they can inspect, budget for what they can price, and stay with what does not trap them. Openness is our moat, not a giveaway: the free viewer drives adoption, and the professional tools people gladly pay for are built on top of it.
Is realvirtual WEB really free under the AGPL?
Yes. Under the AGPL it is free and open source — any project that uses it must itself be published under the AGPL. If you want to keep your application closed or need commercial support, the commercial license is €1,920 net per developer per year plus one deployment fee. Both options are fully documented.
What does it actually cost to start?
Nothing to try it. The Starter edition is free on the Unity Asset Store and the MCP server is free on GitHub. You only pay when you move to Professional (€1,250 one-time, plus a Unity Editor license) or license realvirtual WEB commercially, and every one of those numbers is published right here.
Can I fork it if I ever need to?
For the AGPL-licensed WEB viewer, yes — that is the whole point of open source. For the commercially licensed framework you get full source access to adapt and extend it for your own use. Either way, you are never left waiting on a vendor to unblock you.
Infrastructure you can trust is infrastructure you can see.
