| Availability | The maker says ActorDB has no single point of failure and that a follower can become an actor's leader when a server goes offline. | AWS says Aurora is designed for up to 99.99% single-Region and 99.999% multi-Region availability. |
| Notable limit | The documentation cautions against putting many gigabytes of data inside a single actor and recommends spreading data across actors. | The free plan provides Aurora PostgreSQL Serverless instances with up to 4 ACUs and 1 GiB of storage per cluster. |
| Product | ActorDB is a distributed relational SQL database. | Amazon Aurora is a fully managed relational database service with PostgreSQL, MySQL, and DSQL engines. |
| Scaling | The maker says ActorDB can scale horizontally to hundreds of nodes and petabytes of data. | Aurora Serverless automatically starts, stops, and scales capacity based on application needs, and charges for capacity consumed. |

In their own words
ActorDB
ActorDB is an open-source distributed relational SQL database from Biokoda that organizes data into independent actors. SQLite handles SQL queries and LMDB provides storage. Applications connect through the MySQL protocol or Thrift, and the FAQ recommends Thrift; default MySQL drivers also work. ActorDB uses Raft for distributed consensus and write replication, and describes itself as strongly consistent. Transactions can span multiple actors and are described as ACID compliant. It can also provide a sharded key-value store with structured values, multiple columns, and foreign tables. The maker says horizontal scaling can reach hundreds of nodes and petabytes when data is spread across actors. If a server fails, a follower can lead an actor while a cluster majority remains online. Recommended cluster sizes are 1, 3, or 5 nodes. Supported downloads include Windows, Mac OS X, CentOS, and Ubuntu, with version 0.10.29 dated 1 October 2019 shown as the latest stable release.
