How this list is ordered. Specifiction scores each tool on how fully its maker documents it, whether its prices are published, where the research puts it, the platforms it runs on and whether it can be tried for free (how we rank). Makers can also buy a numbered place (how Specifiction is paid for).

Amazon DynamoDB, Aerospike Database and Riak KV are among the entries to consider. Free-plan availability and paid-from pricing add cost context. Think about the access patterns your application needs, how data should persist, and whether deployment or geographic requirements shape the choice.
