Easy ERDPaste your SQL. See your database.
Easy ERD turns CREATE TABLE statements into an interactive entity-relationship diagram you can label, search, and export. No signup, no install, and your schema never leaves your browser.
Why it exists
Most schema diagram tools ask you to create an account, learn their own modeling language, or upload your DDL to someone else's server. For a client schema or an internal database, that is a non-starter. Easy ERD is a static web page. You paste SQL, you get a diagram, and that is the whole workflow.
What you get
- Private by design. Your SQL is processed 100% in your browser and is never sent anywhere. The site counts anonymous page views, nothing more (details below).
- Handles real dumps. MySQL, Postgres, SQLite, and SQL Server quoting;
ALTER TABLEconstraints; schema-qualified names. - Project labels. Tag tables ("HR Core", "Billing"), then filter and highlight by tag so a big schema becomes readable.
- Easy import. Paste one table or a whole schema, upload a
.sqlfile, or reopen a saved project file. - Easy export. PNG, PDF, SVG, and editable draw.io, in light or dark. Save and reopen a portable project JSON.
- Relationships that read well. Lines connect the actual FK column to the actual PK column, with 1:N / 1:1 labels and link-table detection.
- Multi-select and editing. Box-select, move groups, edit any table's SQL and watch the diagram redraw.
Privacy and analytics
Everything you paste, upload, tag, and export stays in your browser. There is no server that receives your SQL, and no account to tie it to. Your work autosaves in this browser's local storage, which you can clear at any time.
To learn how many people use the tool, the site uses Vercel Web Analytics, which records anonymous page views: which page was opened, the referring site, and the visitor's country, browser, and device type. It uses no cookies and does not identify individual visitors. It never sees your SQL, table names, file names, or anything else you enter. If you open your browser's network tab, you will see that one analytics request to this site's own domain, and nothing carrying your schema.
How it compares
| Tool | Great at | Where Easy ERD differs |
|---|---|---|
| dbdiagram.io | Quick diagrams written in its DBML language | You paste the SQL you already have instead of learning and translating to DBML. |
| drawDB | Designing a schema visually from scratch | Built for the opposite direction: start from existing DDL and understand it fast, with tags for large schemas. |
| Liam ERD | Polished diagrams for developer docs | Interactive editing, tagging, and draw.io export in one paste-and-go page. |
| SchemaSpy | Documenting a live database with full metadata | No Java, no database connection, no setup. Works from a SQL file in seconds. |
| Mermaid erDiagram | Diagrams as text inside markdown | You do not hand-write syntax, and layout is draggable. |
Based on each tool's public pages as of October 2026. These are good tools and the right pick for many jobs.
