Mystra App Count Margin

Mystra's pricing is per app monitored, not per agency client, and that single fact decides whether a retainer is profitable. Free covers 1 app at 25 runs/month with 7-day history and 1 GB of evidence. Starter is $29/month for 3 apps and 500 runs. So a client with one production app fits inside Starter, but a client running staging plus production, or a multi-tenant SaaS with separate checkout domains, can push an agency onto a higher tier while the retainer fee stays flat. Before quoting, count the client's apps and deploys per week, then price the retainer above the Mystra tier that count lands on. A $1,500 Mystra Flow Starter setup at 12h effort only holds margin when the client's app count stays inside the tier you budgeted for. Review app counts at every renewal.
