DBaaS / Serverless Databases
CockroachDB and Amazon DynamoDB diverge first on pricing model: CockroachDB uses hybrid pricing with a free tier, Amazon DynamoDB uses subscription pricing with a free tier. Everything else flows from that commercial choice. CockroachDB is built for apps, global and is not a fit for simple, offline projects. Amazon DynamoDB is built for apps, global and is not a fit for simple, offline projects. On the scoring side, CockroachDB rates 5/5 for developer experience and 3/5 for transparency; Amazon DynamoDB rates 4/5 and 4/5 respectively. The honest trade-off: with CockroachDB you accept that simple key-value storage needs, while Amazon DynamoDB comes with the reality that simple key-value storage needs. Neither side is free. CockroachDB's headline strength in the data is that apps needing managed database. Amazon DynamoDB's headline strength is that apps needing managed database. 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.

CockroachDB uses a hybrid model, while Amazon DynamoDB uses a subscription 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.
CockroachDB has low lock-in (low — postgresql-compatible, standard sql); Amazon DynamoDB has low lock-in (proprietary nosql data model, hard to migrate off). Migration effort scales with how much state and automation you've built in CockroachDB; plan for data export, config rebuild, and a parallel-run period before cutting over.
In our data, CockroachDB 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.
Amazon DynamoDB is built for apps, global and explicitly not for simple, offline projects, so it's a fit only if your workflow matches its stated audience. If you were using CockroachDB for apps, global, the switch is reasonable; outside that scope, look elsewhere.
