DBOS is an open-source library, DBOS Transact, for durable workflows and queues in applications and AI agents. It stores workflow state in a Postgres database that the application already uses, so a program can resume after a failure without a separate orchestration service. The library is released under the MIT licence. The vendor also offers DBOS Cloud and the DBOS Conductor control plane, and Conductor can be self-hosted on-premises or in any cloud.
DBOS, Inc. is a US company. Because the library is MIT-licensed and needs only Postgres, a European organisation can run it entirely on its own infrastructure and keep workflow data under its own control. The regions of DBOS Cloud are not stated on the vendor's pages, so European users of the hosted service should confirm data location and data processing terms in the contract. A US company may be subject to US legal demands regardless of where data is stored.
