The desktop app is free, and it stays free. Hosted is the same thirty-eight tools on a machine that does not close when your lid does — priced by how many browsers you run at once, and nothing else.
No account for the desktop app, and no card. What "free forever" means here.
One axis: how many browser sessions run at the same time. Every feature is in every band — the tunnel, the timeline, the audit queue, every tool, the whole supervision surface. Bands differ by how much of it you may run at once, never by what you are allowed to do.

Billing is switched off here, which is what a self-hosted vitro looks like:
every team is entitled to everything, and the only ceiling is the one the
machine's own VITRO_MAX_SESSIONS sets — the right
authority on hardware you are already paying for. The prices above are what
the hosted service at vitro.run costs, listed so you can see what you are
not being charged.
Metering keeps running either way. It is what tells you which key is holding twelve browsers open at 3am, and that question is just as good on a machine nobody is invoicing.
It is not a trial that expires, a seat you eventually pay for, or a tier with the good tools held back. The same thirty-eight tools, the same timeline, the same window. There is no higher desktop tier, so there is nothing above it to want.
What you pay for, if you ever do, is somewhere else to run it: a machine that stays up when your laptop sleeps, shared with the rest of your team, with the history kept somewhere that survives a reinstall. That is a hosting bill, and it is the only thing being sold.
A browser slot measures 677 MB before it holds a page, and a renderer another 199 MB on top. Concurrency is literally what a machine is bought for, and a team running twelve agents at once is getting twelve times the work out of vitro as a team running one. The price and the cost move together.
Hours are the other obvious meter, and they are the wrong one for a price list. You cannot predict them, they punish leaving a browser open over lunch, and they turn the invoice into a surprise. Concurrency is a number your team already knows about itself.
Not two products. The same Elixir application, packaged twice. An agent reaches either one over MCP and cannot tell the difference, and the hosted console shows the same wall the desktop window does.

No. It is the whole product on hardware we do not pay for, so there is nothing to recover. If that ever changed it would be a different piece of software with a different name, not an update that took this one away.
The team stops being entitled and the API answers 402 until a plan is picked. Nothing is deleted on the day, and the desktop app is still sitting there, still free, with every tool in it.
The next create_session is refused, immediately, with the
reason and the current count — not queued behind a browser that
may never free up. An agent at its band's ceiling gets exactly the
answer it already gets at the fleet's ceiling, which is a path that was
designed to fail well long before anybody was billed for it.
Yes, and billing is off by default when you do. A self-hosted install is vitro plus a dashboard for a team that already owns the machine, and charging them is not something this software can do by accident.
Because the hardware is bought in euro. For a business whose gross margin is mostly a hosting bill, listing in the currency the capacity is priced in matters more than matching the currency of the comparison.
Install it, point one agent at it, and watch what the agent was actually looking at when it went wrong. If you end up wanting the same thing on a machine that never sleeps, it is here.
