ERD Builder Pro Design database schemas and document how your systems work. Documentation · Desktop releases · Docker image ERD Builder Pro combines an ERD canvas and DBML editor with flowcharts, notes, and drawings. Desktop and CLI builds also include DB Client for working with existing PostgreSQL, MySQL, and SQLite databases. Features - Model schemas in the ERD canvas or DBML editor, then export SQL DDL for PostgreSQL and MySQL. - Keep flowcharts, rich-text notes, and drawings alongside project files. - Use DB Client in the Desktop and CLI apps to inspect connected database schemas, browse data, and run queries. - Ask the AI assistant to draft SQL, sample data, or flowcharts. Review generated content before applying it. AI features require a configured provider. Install CLI Requires Node.js 18 or later. The CLI opens the web interface at `http://localhost:3101`, binds its server to `127.0.0.1`, and stores its SQLite database at `~/.erdbpro/data.db`. See the CLI guide for other commands, MCP, and schema checks.

Check the release notes for installation instructions. Docker The published image listens on port `3000` and uses SQLite when `DATABASE_URL` is unset. The database is stored under `/app/data`; mount that path to a persistent volume. Web deployments also require a stable `ERD_ENCRYPTION_KEY`. Keep the `erd-data` volume and `.env` backed up.
