| Data handling | The graphs are virtual, so data remains in its source databases rather than being moved to another database. | Teiid acts as a data gateway and does not store the data it accesses. |
| Deployment | Ontop can be deployed as a SPARQL endpoint using its command-line interface or Docker image. | The project describes Spring Boot, WildFly, embedded Java, and OpenShift deployment options. |
| License | Ontop is available under the Apache 2.0 license. | 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 | Ontop exposes relational database contents as virtual knowledge graphs and translates SPARQL queries into SQL queries executed by the source databases. | Teiid is a Java data virtualization query engine that integrates data from multiple sources through a uniform API. |

In their own words
Teiid
Teiid is a free, open-source data virtualization project that gives applications a uniform way to query multiple underlying sources. It works as a gateway rather than storing the data, and virtual databases can present separate sources together so applications can join or union their results. Access is available through JDBC, ODBC, OData, and REST. Built-in translators are listed for Oracle, DB2, SQL Server, MySQL, PostgreSQL, and files; custom translators can also be made. Its optimizer uses source capability information to send query work to underlying systems where possible. Documented runtimes include Spring Boot, WildFly, embedded Java, and OpenShift, with Spring Boot noted as less feature-complete than WildFly. Teiid is aimed especially at Java developers integrating enterprise data sources. Connecting to sources commonly requires third-party drivers that are not included. The FAQ cautions that big-data, LDAP-style, and primarily streaming workloads may not be a good fit. Teiid Designer is deprecated, with no further releases expected.
