Why we chose lifetime pricing

Most CAD tools charge $50–300/month. Subscriptions make sense for full authoring suites, but a file viewer should not cost more than the files you are reviewing.

CADDaddy is a review and inspection tool. You open a file, check the geometry, measure what you need, export or share, and move on. That workflow does not justify a recurring bill.

We charge $19 once because that is what a fast, reliable viewer is worth — and because we would rather have 10,000 users who paid once than 200 users on a plan they keep meaning to cancel.
