An AI-powered database client and SQL workspace for developers, DBAs, analysts, and data teams.
What is Chat2DB?
Chat2DB Community is a free, cross-platform database client for Windows, macOS, and Linux. It runs entirely on your machine and combines a full-featured SQL workspace with an AI assistant that you connect to your own model.
40+ databases — MySQL, PostgreSQL, Oracle, SQL Server, ClickHouse, MongoDB, Redis, SQLite, MariaDB, TiDB, Hive, DB2, Snowflake, BigQuery, Elasticsearch, Trino, TimescaleDB, Greenplum, YugabyteDB, CrateDB, QuestDB, Apache IoTDB, Firebird, HSQLDB, Apache Derby, and more via plugins — new JDBC databases can be added through configuration only, without code changes.
SQL workspace — editing, completion, formatting, execution, saved SQL, and execution history.
AI assistant — bring your own AI model to generate, explain, and optimize SQL in natural language.
Database management — browse metadata, manage tables and objects (DDL/DML), and edit data in place.
Data import and export, dashboards and charts, and an open-source CLI with MCP support.

Early preview
The next feature line ships as an early preview before it reaches the regular Beta channel:
Chat2DB Community 5.4.0-beta.1 (early preview) — installers for macOS, Windows and Linux.
It adds an optional local agent runtime with skills, external MCP servers, and file and terminal tools; choose Pi Agent in the AI input's runtime selector to enable it (the first selection asks for confirmation and downloads the runtime).
This preview is neither the stable nor the regular Beta release: Latest stays on the stable build, and the regular Beta line continues with 5.3.8-beta.x. Enable Receive Beta versions in Settings → About Us to receive it in the app.
Quick Start
Option 1: Desktop App
Download the installer for your platform from GitHub Releases, install it, and start connecting to your databases. No further setup is required.
Option 2: Docker
Requirements: Docker 19.03.0+, Docker Compose 2.0.0+ (Compose V2, only for the Compose variant), 2+ CPU cores, 4+ GiB RAM.
First create the encryption key (see Encryption Key for why it matters), then start the container:
# Run once from a repository checkout. Re-running reuses the same valid key.
git clone https://github.com/OtterMind/Chat2DB.git && cd Chat2DB
./script/security/init-community-encryption-key.sh
docker run --detach \
--name chat2db-community \
--restart unless-stopped \
--publish 127.0.0.1:10825:10825 \
--volume "$HOME/.chat2db-community-docker:/root/.chat2db-community" \
--env CHAT2DB_COMMUNITY_ENCRYPTION_KEY_FILE=/run/secrets/chat2db-community-encryption.key \
--volume "$HOME/.config/chat2db-community/encryption.key:/run/secrets/chat2db-community-encryption.key:ro" \
chat2db/chat2db:latest
Then open http://localhost:10825 in your browser.
Alternatively, use the bundled Compose definition:
./script/security/init-community-encryption-key.sh
docker compose --file docker/docker-compose.yml up --detach
Notes:
To update, pull the new image, remove the old container, and run the start command again. Keep ~/.config/chat2db-community/encryption.key across rebuilds.
The docker run example stores application data in $HOME/.chat2db-community-docker; the Compose definition uses the chat2db-community-data named volume. These locations do not share data.
Chat2DB Community 5.3.0 uses the independent /root/.chat2db-community directory and does not automatically migrate data from earlier images that used /root/.chat2db.
Security Notes
Chat2DB Community is a single-user, local-first application. It has no user
accounts or authorization boundaries between users. Keep the HTTP service
bound to 127.0.0.1 or ::1 and do not expose it to other users or
untrusted networks.
Custom JDBC drivers are executable Java code — install them only from
sources you trust. Imported configuration files, archives, SQL files,
database contents, and AI responses remain untrusted data. See the
Security Policy for the complete trust boundary and
vulnerability reporting process.

Encryption Key
Chat2DB Community encrypts stored datasource passwords and AI model API keys with AES-256-GCM using a per-installation key. Create it once from a repository checkout (requires openssl):
The key is written to ~/.config/chat2db-community/encryption.key. Back this file up separately and keep it across upgrades and container rebuilds — replacing or losing it makes previously stored datasource passwords and AI model API keys unreadable. Web/headless startup fails when no valid key is provided; only Desktop mode creates a missing key automatically.
The key must be valid Base64 that decodes to exactly 32 bytes. The bundled initializer generates the standard padded form: 44 Base64 characters ending in =. It is cryptographic key material, not a human-readable password. Datasource passwords and AI API keys use the same key with separate authenticated AAD values, so ciphertext from one purpose cannot be decrypted as the other.
To use a custom path, pass it to the script and configure the same path when starting Chat2DB:
The script's key-file path priority is the positional argument, CHAT2DB_COMMUNITY_ENCRYPTION_KEY_FILE, then the default path. It reuses a valid regular file, rejects symbolic links and non-regular files, and refuses to overwrite an invalid file. Keep the key readable only by the Chat2DB process owner.
Key configuration is resolved in this order:
JVM property chat2db.community.encryption-key containing the Base64 key.
Environment variable CHAT2DB_COMMUNITY_ENCRYPTION_KEY containing the Base64 key.
JVM property chat2db.community.encryption-key-file containing a key-file path.
Environment variable CHAT2DB_COMMUNITY_ENCRYPTION_KEY_FILE containing a key-file path.
The first configured value is authoritative. A blank value, malformed Base64, a key that does not decode to 32 bytes, or an invalid key file fails startup instead of falling through to the next source. File-based configuration is recommended because it avoids placing the key value directly in process arguments or environment variables.
Automatic key-file creation depends on chat2db.mode, not chat2db.gui. Community Desktop mode (chat2db.runtime.mode=community with chat2db.mode=DESKTOP) creates the selected key file when no inline key is configured and the file is missing. Any non-Desktop mode, including normal Web/headless startup, never creates a missing key and fails until a valid key is provided or initialized. The resolved key is cached for the process lifetime, so changing key configuration requires an application restart.

Community vs Commercial Editions
The Community edition contains the full local database client described above, including custom AI model support. The commercial Pro and Enterprise editions build on the same core and add hosted AI services, user accounts, cloud storage and multi-device sync, and team collaboration and governance features. See chat2db.ai for details.
