GraphMyDB helps teams understand complex database structures fast. Upload a MySQL, PostgreSQL, or SQLite dump, CSV datasets, JSON schemas, or Excel spreadsheets — and get an interactive ER diagram in seconds. Compare schema versions, preview migrations, collaborate live in the code editor and ER diagram, and click any table or column to focus on its relationships.
Local-first and stateless by default: your files are parsed in the browser and are not uploaded for project storage. When you start co-op, peers join with an invite code and authenticate with a room secret before syncing.
Analyze schemas directly in your browser with no account, no project storage, and no locked workflow around a backend service.
Start a room after loading a database and share an invite code. Up to four people can review the live code tab and ER diagram together.
Right-click any .sql, .json, .csv, or .xlsx file in VS Code and instantly visualize its schema. The extension now supports the same invite-code co-op flow, so browser and VS Code sessions can review the same live schema together.
Install from MarketplaceUse the Compare tab for full snapshot-to-snapshot checks and the Migration tab for base-plus-migration analysis. The changelog explains changes in plain language so non-technical stakeholders can follow.
Drop the old SQL dump or paste DDL to create your baseline.
Add the new version to compute table, column, FK, and index differences.
Inspect highlights in the diagram and confirm details in plain-English changelog.
Upload SQL, CSV, JSON, or Excel files. All parsing happens in your browser — your data never leaves your machine.
GraphMyDB is a free, browser-based tool that lets you visualize SQL schemas as interactive ER diagrams, compare database versions, and preview migration impact — all without uploading data to any server.
GraphMyDB supports MySQL, PostgreSQL, and SQLite — including CREATE TABLE, ALTER TABLE, FOREIGN KEY, INDEX, and all common DDL statements. Code generation is also dialect-aware.
You can upload SQL files (.sql), CSV/TSV files of any size, JSON schema files (.json), and Excel spreadsheets (.xlsx, .xls). All parsing happens entirely in your browser.
Yes. By default GraphMyDB parses files locally in your browser and does not upload your schemas for storage. Optional accounts only cover hosted limits and billing metadata. If you explicitly start co-op, the app uses invite-code collaboration with authenticated peer connections so collaborators can sync the live session without durable project storage.
Yes. Start co-op after loading a database, copy the invite code, and your collaborators can join the same live code and ER diagram session from the browser or the VS Code extension. Hosting may require signing in if hosted limits apply.
Yes. Use the Compare tab to upload old and new SQL dumps (any dialect) for full snapshot-to-snapshot diff, or the Migration tab for base-plus-migration analysis. Changes are shown visually and as a plain-English changelog.
Yes. Files of any size are supported. Large CSVs (100 MB+) are automatically sampled — the first ~2,000 rows are read for fast schema inference. Your browser won't freeze.
Click any table node to focus on its relationships (unrelated items dim). Then click a specific column to highlight the exact edge connected to it in amber. Click the canvas to reset.
You can export the diagram as PNG or SVG from the toolbar, and the schema as SQL DDL, CSV, JSON, or Excel (.xlsx) from the Export tab.
