| Fact | Stardog | Teiid |
|---|---|---|
| Connectors | Stardog connects to more than 80 enterprise sources and offers a generic REST connector for bespoke applications. | Built-in translators are listed for Oracle, DB2, SQL Server, MySQL, PostgreSQL, and files, and custom translators can be created. |
| Deployment | Stardog can run as a managed AWS cloud service, in customer cloud environments, or on premises through Docker, Kubernetes, AWS Marketplace, and Azure Marketplace. | The project describes Spring Boot, WildFly, embedded Java, and OpenShift deployment options. |
| License | Stardog Free is proprietary, licensed software and the pricing FAQ explicitly says it is not open source. | The community page says that starting with Teiid 10.0, the majority of Teiid and related project code is under the Apache License 2.0. |
| Purpose | Stardog connects enterprise data into a semantic layer for AI, analytics, search, and applications. | Teiid is a Java data virtualization query engine that integrates data from multiple sources through a uniform API. |
Stardog suits organizations that need to unify data across cloud and on-premises sources for analytics, AI, search, or applications. It is also relevant to teams that need graph-based data modeling, standards-based querying, and deployment options spanning managed cloud and self-hosting.
Teiid suits Java developers integrating multiple enterprise data sources, particularly those targeting OpenShift. It may be a poor fit for big-data, LDAP-style virtualization, or primarily streaming workloads.
