Design Your Database,
Visually and Instantly
Create professional ERD diagrams with drag-and-drop simplicity. Generate SQL for MySQL, PostgreSQL, Oracle, and MSSQL in seconds.
Everything You Need for Database Design
Powerful tools to design, generate, and manage your database schemas — all in one place.
Visual ERD Editor
Drag-and-drop table design with auto-layout, column editing, and real-time relationship visualization.
Multi-DB SQL Generation
Generate production-ready DDL for MySQL, PostgreSQL, Oracle, and MSSQL with a single click.
SQL Import & Reverse Engineering
Paste your CREATE TABLE SQL and instantly generate an ERD diagram. Supports ALTER SQL too.
Data Dictionary
Manage term, type, and word dictionaries to keep naming consistent across your entire schema.
Share & Collaborate
Generate secure read-only share links with expiration. No account needed for viewers.
Version Management
Create schema snapshots, compare versions side-by-side, and restore any previous state.
Stay in your terminal — the diagram keeps up
An agent already running in your own terminal connects to this diagram and edits it directly. This is what sets it apart from every other ERD editor.
claude mcp add --transport http --scope user erd-studio https://erd-studio.makevox.com/api/mcp --header "Authorization: Bearer <access-token>"It connects with an access token issued per diagram and per person. Codex and Antigravity take the same URL and header in a config file instead of a command.
Tables and columns
Create tables, edit columns and types, and set indexes, UNIQUE and CHECK — all by asking.
Relationships
Add foreign keys down to which column points where, and drop the ones you no longer need.
DDL in and out
Import and export DDL, including ALTER and DROP. No more copying statements back and forth by hand.
Dictionary and groups
Edit the word, type and term dictionary and sort tables into groups, so naming stays consistent across the diagram.
Layout
Rearrange a canvas that has drifted apart as tables piled up, back into something readable.
Health checks
Names built from words missing in the dictionary, foreign keys whose column is gone, references that export into SQL but have no line on the canvas — the things eyes skip.
We don't charge for AI.You use the agent subscription you already pay for. There is no API key to get from us, and we don't run the models. What we do is connect that agent to your diagram.
