DrawX reads the source and lays it out properly — labelled connections, grouped tiers, no overlapping boxes.
Edit it. Own it. Ship it.
It's a native draw.io file. Refine it by chat or by hand, then export PNG, SVG, .drawio or PowerPoint.
What you can generate
- An e-commerce schema with orders, items and payments
- Your real schema, read from Prisma, SQL or migrations in the repo
- A multi-tenant billing model with tenants and subscriptions

Questions, answered
Will it show individual columns?+
Yes. DrawX renders each table as a container with one row per column — name, type and key role — and connects foreign keys to the primary keys they reference, rather than collapsing a table into a single box.
Can I edit the generated Entity Relationship (ERD) diagram?+
Yes — that's the whole point. DrawX outputs a native draw.io (.drawio) file, so you can edit it here, in desktop draw.io, or in any draw.io-compatible editor, forever. No proprietary format and no lock-in.
What can I use as a prompt?+
A sentence, a paragraph, a PDF, a URL, an image of a whiteboard sketch — or a whole GitHub repository. DrawX reads the source and draws what's actually there.
Is it free?+
You get 5 diagram generations a month free, no credit card. DrawX Pro is $9/mo (or $90/yr) for 50 generations with all modes and every export format.
Is there an API or an MCP server?+
Both. There's a public HTTP API (POST /api/v1/diagram/generate with an OpenAPI spec) and an MCP server on the official MCP registry — run `npx @drawx/mcp-server` to generate diagrams from Claude, Cursor or VS Code.
What formats can I export?+
PNG, SVG, native .drawio, and PowerPoint (PPTX) — so the diagram works for the repo, the doc and the meeting.
