One interface. Different engines.

PostgreSQL

The reference engine — pooled connections, full catalog introspection, visual EXPLAIN, ER diagrams, live health and agent mode.

Transport

pg pool · 5432

Reference

docs/providers/postgres.md

Does not do Nothing held back — every capability in the product ships here, including agent mode.

MySQL

Pooled connections with information_schema introspection, EXPLAIN plans and performance_schema-backed monitoring.

Transport

mysql2 pool · 3306

Reference

docs/providers/mysql.md

Does not do Agent mode is unavailable, as on every engine but PostgreSQL, SQLite and DuckDB.

Oracle

Pooled connections with introspection and monitoring through the ALL_* and DBA_* data-dictionary views.

Transport

oracledb pool · 1521

Reference

docs/providers/oracle.md

Does not do Agent mode is unavailable here. Operate still reads the server's own reporting interface.

SQL Server

Pooled connections with sys.* catalog introspection, estimated plans and DMV-backed monitoring.

Transport

mssql pool · 1433

Reference

docs/providers/mssql.md

Does not do Agent mode is unavailable here; the editor, diagrams and health are identical.

SQLite

The embedded engine — a file, no network. Full editor, ER diagrams, EXPLAIN and agent mode.

Transport

file · embedded

Reference

docs/providers/sqlite.md

Does not do There is no server to monitor: health reads file size and pragma statistics only.

libSQL

SQLite's dialect over the network — Turso and self-hosted sqld, spoken natively.

Transport

hrana · 443

Reference

docs/providers/libsql.md

Does not do Monitoring is limited to what the sqld server itself exposes.

DuckDB

In-process analytics — query Parquet and CSV files directly, with full EXPLAIN support and agent mode.

Transport

file · embedded

Reference

docs/providers/duckdb.md

Does not do Single-writer by design: no sessions to list, so health shows storage, not connections.

ClickHouse

HTTP interface with system.* introspection, EXPLAIN pipelines and query-log monitoring.

Transport

http · 8123

Reference

docs/providers/clickhouse.md

Does not do No foreign keys exist, so ER diagrams show structure without discovered relations.

Apache Druid

SQL over HTTP with datasource and segment introspection for streaming analytics.

Transport

http · 8888

Reference

docs/providers/druid.md

Does not do Append-oriented: row editing is disabled rather than offered and then failed.

Apache Trino

Federated SQL — one query across the catalogs you already have, from object storage to RDBMS.

Transport

http · 8080

Reference

docs/providers/trino.md

Does not do Trino queries catalogs; it does not manage a lakehouse. Writes depend on the underlying connector.

MongoDB

Document browsing, aggregation pipelines and index introspection over the native driver.

Transport

driver · 27017

Reference

docs/providers/mongodb.md

Does not do No SQL translation layer is faked — queries here are MongoDB queries.

Couchbase

SQL++ queries with bucket, scope and collection introspection over the documented REST surfaces.

Transport

http · 8091

Reference

docs/providers/couchbase.md

Does not do Agent mode is unavailable, as on every engine but PostgreSQL, SQLite and DuckDB.

Redis

Key browsing by pattern, type-aware value views and INFO-backed live monitoring.

Transport

resp · 6379

Reference

docs/providers/redis.md

Does not do No SQL, and none is pretended — the editor speaks commands here.

LibreDB

The embedded ordered key-value store — a file, no server and no wire protocol. Mapped onto the interface by convention rather than by emulating SQL.

Transport

file · embedded

Reference

docs/providers/libredb.md

Does not do No sessions and no index objects exist, so those two panels are absent with their reason rather than answered empty. Maintenance operations are refused, not faked.

Cassandra

CQL editor with keyspace, table and type introspection for wide-column data.

Transport

cql · 9042

Reference

docs/providers/cassandra.md

Does not do No joins and no EXPLAIN — the grid respects partition-key query rules instead of hiding them.

Elasticsearch

Query DSL and browsing over indices, with mapping introspection and cluster health.

Transport

http · 9200

Reference

docs/providers/elasticsearch.md

Does not do Search engines are query-and-browse: no row editing, no ER diagrams.

OpenSearch

The same query-and-browse surface as Elasticsearch, against OpenSearch clusters.

Transport

http · 9200

Reference

docs/providers/opensearch.md

Does not do Search engines are query-and-browse: no row editing, no ER diagrams.
