How billing works
We sell the software, not your compute and not your data.
Runs on your compute
Every tier runs on your machine with your own model keys. We never host the models. Your code and prompts never touch our servers.
Pro is ownership, not rent
Buy Pro once and own that major version forever, with every update in its line included. A new major generation is a discounted upgrade, never a forced one.
Company stays current
Company is billed per seat per year and auto-renews for the next twelve months. New features ship continuously the whole time the subscription is active.
Private by construction
Licenses are verified offline against a key built into the binary. No phone-home, works air-gapped. We hold billing, never your work.
Compare every plan

Questions
Do you host the models or take a cut of my usage?
No. Atlas runs on your machine with your own provider keys. We never sit in the token path, so there is nothing of yours to meter, log, or resell.
If I buy Pro now, do I get features you add later?
You get every update within the major version you bought, forever. When we ship a new major generation it is a separate, discounted upgrade, and you can always keep using the version you own with no obligation.
Is Pro per machine or per person?
Per person. One Pro seat covers all of your own machines. We never license per device.
What happens when a Company subscription lapses?
The team keeps the last version it was entitled to and simply stops receiving new updates until it renews. Nothing is bricked, because the license is verified offline.
Will my code or prompts ever reach your servers?
No. The agent runs locally against your keys. We hold billing and license records, never your work. Licenses verify against a key built into the binary, so they work air-gapped.
