Pricing
Free for public repos. Pay only for private repos that generate a diagram.
Start with public pull requests for free. Add the GitHub App when your team wants automated structural review on private repositories. Connect as many private repos as you want — your tier is based on how many are active (produced a diagram) during your billing period, not how many you've connected.

How billing works
1. Install the GitHub App and connect as many private repositories as you want — connecting is always free.
2. Your tier is based on how many of those repos actually generate a diagram during your billing period, not how many you've connected. If your active count crosses a tier boundary, you get a 24-hour heads-up before the upgrade takes effect.
3. Stripe handles billing — invoices, cancellation, and the customer portal are all self-serve.
