The open source tier stays free
Cloud is a hosting convenience, not a paywall around features. Nothing that works today moves behind a subscription.
No lock-in in either direction
Self-host now and move to Cloud later, or export and come back. It is the same schema and the same API on both sides.
No usage metering on self-host
We do not count your sends, your templates or your seats. There is nothing phoning home to count them with.
