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.
See it for yourself
- Starter: free on the Unity Asset Store
- Professional: €1,250 one-time, plus a Unity Editor license
- realvirtual: AGPL-3.0, or realvirtual Commercial at €1,920 per developer / year plus one delivery fee from €300 — and it includes realvirtual Unity Starter and Professional as a download. realvirtual Unity Professional is also available separately, without realvirtual Commercial. The Unity Editor licence is not included and must be obtained separately from Unity Technologies. realvirtual Commercial itself does not require Unity — the twin is authored in the browser.

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 really free under the AGPL?
Yes — and it is worth knowing exactly what that costs you, because realvirtual runs in the browser. The usual "it only runs on our server" reasoning does not apply: every visitor you serve receives a copy of the program, so under the AGPL they are entitled to the corresponding source of what you served them — including the components, plugins and logic you built into it, licensed as a whole. If you modified realvirtual and people reach it over a network, that covers your own staff on an internal network too. Geometry stays yours: a GLB of your machine is data. Behaviour is not — rv_extras logic the program executes travels with the work. And the duty is to offer that source to those users, not to publish it to the world. If you want to keep your own code closed, the commercial licence is €1,920 net per developer per year, plus one fee per delivery. Both paths are documented in full. One further condition applies on the free path: under §7(b) the “Powered by realvirtual” origin notice must stay visible in the interface of any version you use, modify or distribute under the AGPL — removing it is permitted only under the commercial licence, and doing it anyway ends your AGPL rights under §8. Every annual licence becomes perpetual after twelve paid months.
Read the full licence termsWhat 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 commercially, and every one of those numbers is published right here. realvirtual Commercial includes the realvirtual Unity Starter and Professional plugins as downloads — an option, not a prerequisite: the digital twin is authored in the browser, so Unity is not required. realvirtual Unity Professional is also available separately, without realvirtual Commercial. The Unity Editor licence is not included and must be obtained separately from Unity Technologies.
Can I fork it if I ever need to?
For the AGPL-licensed parts of the browser platform, yes — that is the whole point of open source. Two things to know before you start: the editor and CAD import are not in the AGPL build, and the “Powered by realvirtual” notice has to stay visible in an AGPL fork (§7(b)). For the commercially licensed framework you get full source access to adapt and extend it for your own use, and the notice may be removed. Either way, you are never left waiting on a vendor to unblock you.
