Does DataDoe write to Amazon today?

Yes. Its site says Actions can reprice SKUs, edit listings and images, add negative keywords, adjust PPC, confirm shipments, and cancel orders. Writes stay off until you enable them, and every change is logged.

Does DataDoe have a permanent free plan?

No. The pricing page states one plan at $97 per month with a 14-day free trial. That is a trial, not a $0 plan that stays free.

Does Spillmark replace DataDoe's warehouse?

No. DataDoe's strength is normalized tables, BigQuery, and a REST API with up to 2 years of history. Spillmark does not offer that warehouse.
