Frequently asked questions

1. What is a workspace?

In Structurizr, a workspace is the wrapper for your software architecture model, views and supplementary documentation. We recommend that a workspace contains the model, views and documentation for a single software system. See Workspaces - Scope for more details.

2. Do subscriptions belong to users or workspaces?

A subscription belongs to a user account and paid features are associated with the workspace(s) owned by the user who has the subscription. If you transfer a workspace from a paid subscriber to a free user, that workspace will lose the paid features. Subscriptions cannot be transferred between users.

3. Per team pricing, not per user?

Unlike typical software modelling and documentation tools, where the pricing is hundreds/thousands of dollars "per user", Structurizr's pricing is designed to be "per team", for whatever your own definition of a "team" is.

"Per user" licensing tends to result in a common anti-pattern where a small number of people end up being responsible for updating diagrams, with the resulting diagrams often being manually exported to static images for inclusion in documentation or wiki pages. We think that good software architecture diagrams and documentation should be accessible by everybody on the team, rather than just those lucky few individuals who are fortunate enough to have licenses for tooling.

Workspaces owned by a paid customer can be shared with free users, so you only need to purchase one subscription for your team.

4. Is there a free trial of the paid features?

Yes, after signing up for a free account, you can activate a free 14 day trial by using the link on your dashboard. This trial allows you to create up to 5 workspaces and unlocks all of the available features. This is obligation free and no payment details are required. After the trial period, your account will revert back to a free account. We're happy to extend your trial for another 14 days if you get in contact with us, but we will not provide additional trial periods after this.

5. Do you manage credit card details yourself?

No, we use Braintree Payments (a PayPal company).

6. Which credit cards do you accept?

We accept Visa, Mastercard, and American Express.

8. What's your refund policy?

  • Payments for cloud service subscriptions are refundable within 7 days of the payment date.
  • Paid support packages are non-refundable.

9. What happens to workspaces when a paid subscription expires?

Users with a free account can create one workspace so, when your subscription expires, the workspace that you created first will be retained as-is. The other, more recent, workspaces will be retained too, but marked as read-only. You can still view the workspace content (via the UI and web API) but no changes can be made. To make changes to these read-only workspaces, you can either (1) upgrade to a paid plan, or (2) export the workspace as a JSON file, and import it to one of your active workspaces. Any paid features features you were using (e.g. sharing links, iframe embeds, etc) will no longer work.

10. Can we purchase an annual subscription?

Yes, we can provide a non-renewing annual subscription, under the following terms:

  • Payment terms: Net0 - Delivery on payment. Subscriptions will be assigned once payment has been received.
  • Payment methods
    • Credit card via PayPal: Yes.
    • Bank transfer (SWIFT/IBAN or UK): Only available for payment amounts over $2,500.
    • Checks/cheques: No.

11. Can we purchase via a reseller?

We can provide a cloud service subscription via a reseller under the following conditions:

  • The minimum subscription period is one year (monthly subscriptions cannot be purchased via a reseller).
  • We do not provide any reseller discounts.
  • Payment terms: Net0 - Delivery on payment. Subscriptions will be assigned once payment has been received.
  • Payment methods:
    • Credit card via PayPal: Yes.
    • Bank transfer (SWIFT/IBAN or UK): Only available for payment amounts over $2,500.
    • Checks/cheques: No.
  • We will need to know the e-mail address of the Structurizr user (your customer) that the subscription will be granted to; they will need to sign up via if they are not yet registered.
  • We do not send reminders when subscriptions are due to expire. If you would like to renew the subscription, please contact us before it expires to avoid any disruption.
  • All subscription allocation is undertaken by Structurizr Limited - resellers have no ability to do this on our behalf.

Please contact with your business name, address, and any purchase order details. We also need to know the e-mail address of your customer that the subscription should be granted to.

12. Can you complete our supplier/vendor registration?

We will only complete supplier/vendor registrations for a minimum annual spend of $2,500. See Company details for our a link to your company details.

13. Can you complete our security questionnaire/risk assessment?

We're a small company offering a self-service product at an affordable price, and we therefore don't have the resources to complete security/risk assessment questionnaires. We have tried to include as much relevant information on the Cloud service - Security page but, if you do have a small number of specific questions after reading these pages, feel free to contact us.

For organisations concerned about the longevity of a small company and/or have data security concerns, we'd recommend using the on-premises installation. We have customers who have installed the on-premises installation on their own servers, and on the AWS/Azure clouds. On-premises subscriptions include perpetual usage, so you'll be able to continue using the on-premises installation, although you'll only receive support and updates with an active subscription. Alternatively, you may want to look at Structurizr Lite, and the open source Structurizr ecosystem has a number of other diagram rendering options.

14. Do you have a W9 form?

No, Structurizr Limited is not a US-based company. We do have a W-8BEN-E though, please e-mail us for a copy.

15. Do you have a VAT number?

No, Structurizr Limited is registered in Jersey (Channel Islands), so we do not have a UK/EU VAT number.

16. Can we alter the terms and conditions, or use our own contract?

We're a small company offering a self-service product at an affordable price, and we are therefore unable to accommodate client-specific terms and conditions at this time.
