ArchFoundry designs, prices and deploys infrastructure in AWS accounts you connect. It reads an account through a read-only role you create, and changes it only through a separate deploy role you grant, and only after a person in your organization approves the plan. Coding agents you connect can request infrastructure; they cannot approve it.
You keep ownership of your diagrams, your code and everything in your accounts, and you must have the authority to connect the accounts and repositories you connect. What ArchFoundry deploys runs in your AWS account and AWS bills you for it. Prices ArchFoundry shows are estimates from published list prices; your bill is AWS's.
An organization is on one of three plans: Free, Pro at $20 a month or Enterprise at $120 a month, for the whole organization. Paid plans are billed through Stripe, which handles your card: it never reaches ArchFoundry. Each plan includes an amount of Archie's AI usage a month: $1 on Free, $10 on Pro and $60 on Enterprise. On every plan, Archie stops when it is used up, until the next month on Free and until the plan renews on Pro and Enterprise. Nothing is charged for usage beyond the plan's price, except extra usage an owner or admin chooses to buy. On Pro and Enterprise, $10 of extra usage costs $10.61, paid once and not monthly. It is used after the plan's included usage, and what is left carries over while the organization has a paid plan. On Free, an organization keeps one saved architecture at a time. One that has more, from a paid plan or from before, keeps all of them to open and to delete, and only the one edited most recently can be changed. Owners and admins change or cancel the plan in the Stripe billing portal, from Settings.
Do not use ArchFoundry to reach accounts, systems or workspaces that are not yours, or to get around its limits. Load tests only ever target the load balancer of a deployment in your own workspace, and stay within the caps the product sets.
ArchFoundry is in early access and is provided as it is. Features will change. If these terms change in a way that matters to you, we will tell you in the app or by email before the change applies.
You can stop at any time: destroy your deployments, remove connections in Settings, and delete the IAM roles you created in your AWS account, which ArchFoundry cannot delete for you. To have your account and workspace data deleted, write to legal@archfoundry.ai. We may suspend an organization that breaks these terms.
Questions about any of this: create an account and ask us, or write to legal@archfoundry.ai.
