What Pro unlocks

More room for the parts of testing that expand as your product grows.

Larger test runs

Exercise busier signup, notification, and release flows without hitting the hourly cap as quickly.

More room to inspect

Keep larger volumes of message data available while validating templates and delivery behavior.

A longer debugging window

Choose a retention period that matches the pace of each active QA cycle.

Keys for each environment

Separate API access for local development, CI, staging, and production integrations.

Public API fair-use limit: 10 requests per second. This API request limit is global and not a plan differentiator.
