What is a DBML editor?

A DBML editor is a tool designed for writing Database Markup Language (DBML) and visualizing the resulting database schema. The VPasCode DBML editor is an online tool that provides a live-rendering DBML viewer, so you can see your ERD update in real time as you define tables, columns, and relationships in code.

Is this a free DBML diagram editor?

Yes, the core functionality is completely free. Our free DBML diagram editor allows you to write DBML, view the schema, and export it to PNG or SVG without any cost.

Can I use this tool as a DBML viewer?

Absolutely. If you already have DBML code, you can paste it directly into our online editor. It will function as an instant online DBML viewer, rendering your schema visually without any setup required. It's the fastest way to turn DBML into a diagram.

How do I convert DBML to an ERD?

Our tool does this automatically. 'DBML to ERD' is the core function of our editor. As you write DBML, the tool parses it and renders a clear Entity Relationship Diagram (ERD). You can then export this ERD for your documentation or presentations.

Is Your Database Schema Just Code?

DBML is fantastic for defining schemas as code, but raw text can't show the whole picture. Without a visualizer, spotting relationships and explaining the architecture to your team is a struggle. You need more than just text—you need a powerful DBML viewer that brings your schema to life.

Instant DBML to ERD Visualization

Our online DBML editor is the bridge between your code and clarity. As you define tables, columns, and relationships, a professional Entity Relationship Diagram (ERD) is rendered in real time. This instant DBML to ERD conversion makes it the perfect database diagram tool for agile development.

Your DBML Editor Questions, Answered

What is DBML?

DBML stands for Database Markup Language. It's a simple, readable DSL created for defining database schemas. It allows developers and database architects to design, document, and collaborate on database structures in a code-first, version-controllable way. Our DBML editor makes this process visual and interactive.

Can this tool function as a simple DBML viewer?

Yes. If you have a DBML file, you can simply paste its contents into the editor. It will immediately function as an online DBML viewer, rendering a complete ERD for you to inspect, share, or export.

Does the 'DBML to ERD' feature support all DBML syntax?

Yes, our DBML to ERD renderer supports the full DBML specification, including tables, columns with data types, primary keys, foreign key relationships (many-to-one, one-to-one), indexes, enums, and project-level definitions.
