 ## Features
 
 ### 100+ Databases, One Tool
 
-MySQL, PostgreSQL, SQLite, Cloudflare D1, Redis, MongoDB, DuckDB, ClickHouse, SQL Server, Oracle, Elasticsearch, Easysearch, Meilisearch, Qdrant, Milvus, Weaviate, MariaDB, TiDB, OceanBase, openGauss, GaussDB, KWDB, KingbaseES, Vastbase, GoldenDB, Doris, SelectDB, StarRocks, Manticore Search, Redshift, DM, TDengine, XuguDB, CockroachDB, Access, HighGo, UXDB, Dolt, and more. Agent-based profiles extend DBX to H2, Snowflake, Trino, PrestoSQL, Hive, DB2, Informix, Neo4j, Cassandra, BigQuery, Cloud Spanner, Kylin, SunDB, JDBCX, and custom JDBC connections. New native and agent-driven drivers also cover Databricks, SAP HANA, Teradata, Vertica, Firebird, Exasol, YashanDB, GBase 8a/8s, Databend, RQLite, Turso, InfluxDB, QuestDB, IoTDB, etcd, ZooKeeper, Nacos, Consul KV, IRIS, and more. Message queue admin is also available for Pulsar, Kafka, and RocketMQ. All in a single ~25 MB app. No bundled Chromium.

+### Message Queue & Middleware Consoles
+
+- **Kafka / RocketMQ / RabbitMQ / Pulsar** — topics, consumer groups, message browsing, query and trace, broker monitoring, permissions and policies
+- **MQTT** — topic tree navigation, subscribe, and publish
+- **Nacos / Consul / ZooKeeper / etcd** — service discovery, KV / config browsing, health, and ACL
+
+### Plugin System
+
+- **Extensible by design** — new connection types and tools arrive as plugins: S3 browsing, Kubernetes, LDAP, and more from the built-in store
+- **Signed & sandboxed** — every plugin package is signature-verified before install; plugin UI runs sandboxed with its own sidecar process
+- **Build your own** — Go / TypeScript SDKs with `npx @dbx-app/plugin-cli` scaffolding; publish to the Marketplace via [`t8y2/dbx-store`](https://github.com/t8y2/dbx-store)

 ### Safety & Connectivity
 
 SSH tunnel (key & password) · database and AI proxy settings · auto-reconnect on connection loss · confirmation dialogs for destructive operations · encrypted config export/import · color-coded connections · driver store and optional JDBC plugin
