Datastore guides
Every guide uses the same safe path—connect, explore, scope, read, inspect, export, diagnose, and transfer—then names the controls and limits that differ for that engine.
SQL and relational
8 enginesPostgreSQLPostgreSQL gets a typed SQL workbench with rich catalog views, live read execution, primary-key row evidence, and guarded operational previews.AvailableCockroachDBCockroachDB uses PostgreSQL-style SQL with distributed database posture, Cockroach Cloud metadata, and preview-first cluster operations.AvailableSQL Server/Azure SQLSQL Server and Azure SQL expose TDS SQL, Showplan rendering, Query Store, Extended Events, Agent posture, and guarded table/file workflows.AvailableMySQLMySQL combines live SQL, Workbench-style metadata, performance_schema diagnostics, and guarded table maintenance previews.AvailableMariaDBMariaDB shares the MySQL-compatible base and adds MariaDB-specific roles, storage engines, server variables, and ANALYZE FORMAT=JSON workflows.AvailableSQLiteSQLite is treated as a local-file workbench with file posture, PRAGMA health, integrity checks, guarded VACUUM INTO, and table import/export.AvailableOracleOracle 19c+ uses a bundled managed driver for live SQL and PL/SQL, schema and package inspection, DBMS output, plans, and guarded writes.AvailableTimescaleDBTimescaleDB builds on PostgreSQL with hypertables, chunks, compression, retention, continuous aggregates, jobs, Toolkit checks, and time-bucket dashboards.Available
Document and NoSQL
5 enginesMongoDBMongoDB uses a document-first workbench with collection builders, aggregation helpers, explain dashboards, diagnostics, and guarded document edits.AvailableDynamoDBDynamoDB exposes typed endpoint and credential flows, table/key/index metadata, read-only PartiQL, capacity signals, and guarded conditional item operations.AvailableCassandraCassandra runs bounded CQL reads over the native binary protocol and adds partition-key query helpers, tracing, storage health, grants, and snapshot/import/export planning.Available for CQL reads; writes and administration are guardedCosmos DBCosmos DB supports parameterized SQL API reads with a visual NoSQL builder and bounded continuation-token paging, plus a native GraphSON v2 Gremlin WebSocket runtime with Cosmos authentication, bounded graph results, and request-charge metrics.Available for NoSQL queries; cloud administration is guardedLiteDBLiteDB is documented as a local document-file workflow with collection metadata, index and file storage panels, sidecar boundaries, and guarded local management.Available through the bundled LiteDB runtime
Key-value and cache
3 enginesRedisRedis opens in a native key browser with type-aware results, console mode, Redis Stack capability gates, live guarded key edits, and file import/export workflows.AvailableValkeyValkey uses the Redis-compatible core workflow while hiding Redis Stack/vector-only surfaces unless compatible metadata proves support.AvailableMemcachedMemcached is documented around known-key operations and server diagnostics because it has no portable native key browser.Available for known-key reads; broad enumeration is unavailable
Search
2 enginesElasticsearchElasticsearch focuses on search DSL builders, mappings, shard/profile diagnostics, explicit-id document edits, and guarded index/admin previews.AvailableOpenSearchOpenSearch mirrors scoped search workflows and adds OpenSearch-specific SQL, ISM, security, and Performance Analyzer boundaries.Available
Warehouse and analytical
4 enginesClickHouseClickHouse is documented as a warehouse-style SQL surface with MergeTree, query-log, cluster, TTL, optimize, freeze, metrics, and import/export previews.Available for HTTP SQL and transfersDuckDBDuckDB is a local-file analytics workbench with local read SQL, EXPLAIN/profile rendering, extension posture, CSV import/export, and backup-folder execution.AvailableSnowflakeSnowflake is documented as a SQL-first warehouse workflow with account/project posture, query history, credits, warehouses, stages, shares, and clone/copy previews.Preview for local/proxy query endpointsBigQueryBigQuery uses GoogleSQL, project/dataset/table metadata, dry-run estimates, job timelines, slot and reservation posture, and guarded cloud-operation previews.Available for Prometheus HTTP queries and bounded exports
Time-series and metrics
3 enginesInfluxDBInfluxDB keeps org, bucket, token, tag, field, retention, cardinality, Flux/InfluxQL, and chart-ready result context visible.Available for OpenTSDB HTTP queries and bounded exportsPrometheusPrometheus focuses on endpoints, metric and label discovery, PromQL, targets, rules, chart-ready results, cardinality, retention, and guarded metadata previews.PreviewOpenTSDBOpenTSDB documents metric, tag, UID, stats, retention, profile, and guarded metadata operations for time-series APIs.Preview
Graph
4 enginesNeo4jNeo4j runs live Cypher over Bolt by default or the current HTTP Query API, with bounded graph normalization, live metadata, and guarded mutations.Available for Bolt and Query API connectionsAmazon NeptuneAmazon Neptune runs Gremlin and openCypher through the AWS Neptune Data SDK and signs SPARQL with SigV4, while explicit custom endpoints can use unsigned HTTP.Available for AWS IAM queries; some cloud diagnostics are limitedArangoDBArangoDB runs live AQL through an authenticated TLS-capable HTTP client, consumes bounded cursor batches, and cleans server cursors on completion or failure.Available for HTTP and AQL queriesJanusGraphJanusGraph runs live GraphSON v3 Gremlin over WebSocket with SASL, partial-response aggregation, TLS/custom CAs, bounded graph results, and live schema metadata.Available for Gremlin WebSocket queries
