dbdiagram.io and DBML

dbdiagram.io is a free, simple tool for drawing database diagrams (ERDs) by typing DSL (Domain Specific Language) code. The platform utilizes the popular DBML (Database Markup Language), which was born from dbdiagram.io itself. As of February 2025, DBML has seen significant adoption with 2.5 million documents created and 1.4 million users utilizing the language.

Key aspects of dbdiagram.io include: - Free access to basic database diagram creation features - Support for DBML syntax for diagram definition - Command-line tool (CLI) for converting between SQL (DDL) and DBML - Community-driven development with open-source availability on GitHub

DBML was developed when the creators couldn't find a simple tool they liked for designing database structures. After one year and over 100,000 diagrams created by 60,000 internet users, the syntax designed for drawing diagrams was well-received, leading to the creation of DBML as a standalone language for designing and documenting database structures.

The community has contributed various tools and integrations for DBML, including: - Emacs Mode for DBML by ccod - Vim Plugin for DBML by jidn - VSCode Plugin for DBML by duynvu - Python parser for DBML by Vanderhoof - FloorPlan: Android's Room to DBML by julioz - Go parser for DBML by duythinht - DbmlForDjango: Converter between Django models.py and DBML

This ecosystem of tools makes DBML a versatile option for developers working in different environments and with various programming languages.
