## ChartDB

ChartDB attacks a familiar annoyance: understanding an unfamiliar or sprawling database schema. Rather than installing a heavy modeling suite with database access, it asks you to run one read-only query per DBMS — the project publishes a ready-made query for PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, ClickHouse, CockroachDB, Oracle, Snowflake, and BigQuery. Paste the output JSON and you get a full, interactive ER diagram that you can rearrange, annotate, and export.

Beyond visualization, ChartDB works as an editor. You can add tables, subject areas, and sticky notes, edit relationships, use a DBML editor for text-driven modeling, and produce clean DDL scripts in your preferred SQL dialect. The AI ER diagram generator goes the other direction: describe what you want and get an editable, optimized schema draft. Diagrams are also exportable as images or embeddable previews for docs and wikis.

The project is open source under AGPL and has accumulated tens of thousands of GitHub stars, which is why a self-hosted deployment is available alongside the Cloud product. Cloud plans add real-time collaborative editing, database auto-sync that keeps diagrams current as the schema changes, change logs and versioning, and an AI assistant. Teams get multi-user workspaces, 2FA, and priority support; larger organizations can request custom SSO and RBAC terms.

**Pricing & Plans:** ChartDB offers a genuinely free open-source tier (self-hosted, AGPL) that includes all core features and up to two diagrams. Cloud plans run about US$25/month for a single user (Pro) and US$59/month for teams, with annual billing discounts of up to 40%. Custom enterprise pricing covers SAML SSO and granular permissions.

- **One-query schema import:** Paste a single read-only query result and ChartDB renders the whole schema as an ER diagram, with no direct database access or local agent required.
- **AI ER diagram generator:** Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL.
- **DDL and diagram export:** Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation.
- **Auto-sync and versioning:** On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift.
- **Real-time collaboration:** Invite teammates to view and edit diagrams simultaneously, with multi-user workspaces and 2FA on team plans.

**Strengths:** Truly open source with a generous free self-hosted option and no database access needed; Fast setup — a single query gets you a complete interactive diagram in seconds; Broad DBMS coverage including PostgreSQL, MySQL, SQL Server, SQLite, ClickHouse, Snowflake, BigQuery, and Oracle; AI generation works both ways: prompt-to-diagram and diagram-to-DDL

**Limitations:** Cloud collaboration, auto-sync, and the AI assistant are paid; the free self-hosted tier limits you to two diagrams and ten tables each; Snowflake and BigQuery support sits on higher-tier plans; As a specialized ERD tool it does not replace a full data-governance or lineage platform

## Chat2DB Local

Chat2DB is an AI-assisted SQL client that reframes database work as a conversation. Instead of writing every query by hand, you connect your data sources, describe what you want, and Chat2DB generates optimised SQL from natural language, backed by a context-aware AI chatbot, a schema-aware SQL editor, and one-click fixing when a query fails. The project supports more than 30 databases, spanning relational systems like MySQL, PostgreSQL, Oracle, SQL Server, Snowflake, and BigQuery alongside non-relational ones such as MongoDB, Redis, ClickHouse, and Cassandra, so teams can work in one interface rather than switching clients.

Beyond query generation, the product covers the practical work of managing a database: visual tables, ER diagrams, smart sorting and advanced filtering, schema and data migration, and import/export for CSV, XLSX, XLS, and SQL files, all designed to stay stable with millions of rows. An AI analysis layer answers business questions and generates BI dashboards with charts automatically, and a business-terms feature lets administrators annotate columns so the AI understands domain-specific language and produces better queries.

Security is treated as a first-class concern because the AI needs to see your structures. Chat2DB states that queries run locally and that it perceives schema only, never uploading table data to the cloud or an LLM. The client adds two-factor authentication, AES and RSA encryption in transit and at rest, SSH tunnelling for private databases, least-privilege access, and SQL auditing for administrators. It is an open source project released under Apache 2.0 and available as a desktop client with a cloud option, which is why it has become widely adopted among developers, data teams, and analysts.

**Pricing & Plans:** Chat2DB offers a free tier alongside paid plans, with a cloud offering and a desktop client for local databases. Because tiers and enterprise or API options change, the official pricing page is the authoritative source for current costs; the open source edition is freely available under Apache 2.0.

- **Text to SQL and AI SQL editor:** Type a question in plain language and Chat2DB generates optimised SQL against your connected data sources, with context-aware chat and one-click error fixing.
- **30+ databases in one client:** Connect and manage relational and non-relational databases — including local and cloud sources — from one desktop client instead of juggling separate tools.
- **GUI data management and ER diagrams:** Visual data management with table copilot, ER diagrams, smart sorting, advanced filtering, and schema synchronisation.
- **AI data analysis and BI dashboards:** Ask questions and get AI-generated dashboards with auto-created charts and chain reasoning, turning query results into shareable insight.
- **Migration, import/export, and big-data stability:** Move schemas and data between systems, import and export CSV, XLSX, XLS and SQL files, and handle millions of rows with stable performance.

**Strengths:** Natural-language text-to-SQL removes the need to memorise query syntax; Supports 30+ relational and non-relational databases in one client; Open source under Apache 2.0 with strong community adoption; Local processing with schema-only perception, plus encryption, SSH tunnelling, and SQL audit
