DBaaS / Serverless Databases
Amazon DynamoDB and QuestDB diverge first on pricing model: Amazon DynamoDB uses subscription pricing with a free tier, QuestDB uses freemium pricing with a free tier. Everything else flows from that commercial choice. Amazon DynamoDB is built for apps, global and is not a fit for simple, offline projects. QuestDB is built for teams without a dedicated dba and is not a fit for on-premise or air-gapped requirements. On the scoring side, Amazon DynamoDB rates 4/5 for developer experience and 4/5 for transparency; QuestDB rates 5/5 and 5/5 respectively. The honest trade-off: with Amazon DynamoDB you accept that simple key-value storage needs, while QuestDB comes with the reality that vendor-specific features increase lock-in. Neither side is free. Amazon DynamoDB's headline strength in the data is that apps needing managed database. QuestDB's headline strength is that managed database removes operational overhead. Read each side's best-for and not-for fields carefully before you pick; the shape of your team and workflow matters more than any single score.

Amazon DynamoDB uses a subscription model, while QuestDB uses a freemium model, and both publish a free tier. We don't have per-seat numbers in this dataset, so 'cheaper' depends on volume. Price both on your actual usage before deciding.
Amazon DynamoDB has low lock-in (proprietary nosql data model, hard to migrate off); QuestDB has low lock-in (oss time-series db, self-hostable). Migration effort scales with how much state and automation you've built in Amazon DynamoDB; plan for data export, config rebuild, and a parallel-run period before cutting over.
In our data, QuestDB scores 5/5 for developer experience versus 4/5 for Amazon DynamoDB. That said, DX is subjective; the Amazon DynamoDB score may still be acceptable if its feature fit is stronger for your use case.
QuestDB is built for teams without a dedicated dba and explicitly not for on-premise or air-gapped requirements, so it's a fit only if your workflow matches its stated audience. If you were using Amazon DynamoDB for apps, global, the switch is reasonable; outside that scope, look elsewhere.
