Do you mean a Prefect Cloud subscription? If you’re self‑hosting Prefect Server on your EC2 instance, there’s no subscription to cancel. If you’re on Prefect Cloud, here’s how to cancel or downgrade to Free: - Sign in to Prefect Cloud. - Switch to the correct organization (if you have multiple). - Go to Organization Settings → Billing. - Click “Manage subscription” to open the Stripe customer portal. - In Stripe, choose Cancel plan or Downgrade to Free and confirm. Changes typically take effect at the end of your current billing period. Notes: - You need to be an Organization Owner to access Billing. - If you don’t see Billing/Manage subscription (or if you purchased via invoice), contact Prefect Support via the in‑app Help option or email support@prefect.io. You can also use this contact form. If you’d like, share your org name (as shown in Cloud) and I can help make sure it’s routed correctly.
