ERD LIVE is a collaborative ERD tool for designing database schemas by moving bidirectionally between DDL and a visual canvas. As light as Figma but specialized for data modeling, it features Yjs CRDT-based real-time co-editing, an AI schema assistant, and structural version diffs.
Why ERD LIVE
The disconnect between code and diagram — most ERD tools flow only one way, so SQL and the drawing quickly drift apart.
Collaboration that's just screen sharing — co-editing isn't possible or it conflicts, making team schema reviews a hassle.
Not knowing what changed — text diffs make it hard to read structural changes at the table, column, and FK level.
Key Features
Bidirectional DDL ↔ canvas
Paste SQL DDL to generate an ERD, and canvas edits flow back to DDL. Convert across four dialects: MySQL, PostgreSQL, SQLite, and SQL Server.
Real real-time collaboration
Conflict-free co-editing with Yjs CRDT. See collaborator avatars, remote cursors, and selections in real time.
AI schema assistant
Describe a table in natural language and it suggests DDL, flagging normalization, indexes, and potential issues. Apply suggested DDL in one click.
Version history & structural diff
Save snapshots and restore anytime. Compare differences between versions at the table, column, and FK level, and line by line in DDL.
A local parser for fast edits
DDL edits don't go through AI every time, so they apply to the canvas instantly and for free.
Sharing & permissions
A three-tier Workspace · Project · Diagram structure, role-based permissions (owner/admin/editor/viewer), token-based share links, and an audit log.
How to Get Started
Paste or draw
Paste existing DDL, or draw tables on a blank canvas.
Refine
Connect relationships by dragging, edit columns in the Inspector, and let AI handle improvements.
Share & collaborate
Invite your team to edit together in real time or share externally by link, and roll back by version anytime.
