In their own words
MindsDB Query Engine
MindsDB Query Engine provides SQL access to connected data sources and semantic search, including for AI agents that need live, queryable data. It connects to more than 200 sources and runs federated queries against them in place, using one SQL dialect without copying data or using ETL pipelines. Listed source examples include PostgreSQL, MySQL, MongoDB, Snowflake, BigQuery, S3, and Slack. Users can work in an HTTP SQL editor or connect clients such as DBeaver and SQLAlchemy through MySQL and PostgreSQL wire protocols. For unstructured content, knowledge bases pair an embedding model with a vector store and, optionally, a reranking model. Hybrid search combines vector similarity with BM25 keyword matching. Projects organize work, views preserve cross-source transformations, and scheduled jobs run SQL at intervals. Deployment options include Docker and PyPI installation. The engine is available for Linux, web, API, and self-hosted use. The free plan is listed at free; MindsDB Core uses the Elastic License 2.0, and some repository directories have separate licenses.
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.
