Your database schemas, hosted in France
A web-based database diagram (ER) editor powered by ChartDB, installed and maintained by DINAO. Import, visualize, and document your schemas in seconds — all on our French servers.
What is ChartDB?
ChartDB is a self-hostable web-based database diagram (entity-relationship schema) editor. It allows you to visualize and document the structure of your databases without installing an agent or providing a password: you run a simple « Smart Query » that returns the schema in JSON format, and ChartDB instantly draws it.
The resulting diagram is interactive: you edit tables, columns, relationships, and annotations directly on screen. ChartDB supports many DBMSs — PostgreSQL, MySQL, SQL Server, MariaDB, SQLite, CockroachDB, ClickHouse — and requires no account to function.
An AI-assisted DDL export feature generates migration scripts to switch between SQL dialects. It is configured via the OpenAI API or a custom inference server (e.g., vLLM), making it compatible with a sovereign AI hosted on-premise. The whole solution deploys via Docker.

This application uses AI
The container hosts the application, not the AI engine (which requires dedicated GPUs) : inference is handled externally, with your own provider key. Prioritize a sovereign engine — Mistral AI, NumSpot, Scaleway, or OVHcloud AI Endpoints (France, GDPR) ; an international provider (OpenAI, Anthropic…) only if a specific capability requires it. Inference subscriptions are not included in hosting.
Technical details
You might be wondering…
Do I need to give ChartDB access to my database?
No. ChartDB imports your schema via a « Smart Query » that you run yourself: it returns the structure in JSON format, which you paste into the tool. No agent to install, no password to provide.
Which DBMSs are supported?
PostgreSQL, MySQL, SQL Server, MariaDB, SQLite, CockroachDB, and ClickHouse. ChartDB visualizes their schema and helps migrate between dialects.
How does the AI-assisted DDL export work?
The AI generates DDL scripts to switch between SQL dialects. It is configurable via the OpenAI API or via a custom inference server — so you can connect it to a sovereign AI hosted by DINAO. The core visualization feature works without AI.
Where are my diagrams hosted?
On DINAO infrastructure in France, in one of the available datacenters. The structure of your databases never leaves the territory.
Can I export my diagrams?
Yes. Your diagrams and generated scripts remain exportable at any time — no proprietary lock-in.
