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.

Which SQL dialects does GraphMyDB support?

GraphMyDB supports MySQL, PostgreSQL, and SQLite including CREATE TABLE, ALTER TABLE, FOREIGN KEY, INDEX, and all common DDL statements.

What file formats can I upload?

You can upload SQL files (.sql), SQLite databases (.db, .sqlite, .sqlite3), CSV/TSV files of any size, JSON schema files (.json), and Excel spreadsheets (.xlsx, .xls). Parsing happens in your browser.

Is my data private when using GraphMyDB?

Yes. By default GraphMyDB parses files locally in your browser and does not upload your schemas for storage. If you explicitly start a co-op session, GraphMyDB uses a signaling service plus authenticated peer connections so collaborators can sync the live document without accounts or durable project storage.

Can I collaborate live with other people?

Yes. GraphMyDB supports invite-code co-op sessions for live collaboration on the shared SQL or JSON code. The ER diagram updates locally from that code while each participant keeps independent zoom, pan, and layout control.

Can I compare two database schemas?

Yes. Use the Compare tab to upload old and new SQL dumps 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.

Can I upload large CSV files?

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.

How do I trace a specific column relationship?

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.

What export formats are available?

You can export the diagram as PNG or SVG from the toolbar, and the schema as SQL DDL, CSV, JSON, Excel (.xlsx), or a generated SQLite .db file from the Export tab.

GraphMyDB Release Notes

This release introduced the full co-op workflow, production collaboration fixes, SQLite `.db` support, and a refreshed VS Code extension package. The result is a more practical browser database workspace for live reviews and schema exploration.

Open GraphMyDB Explore the VS Code Extension

Invite-Code Browser Co-op

Introduced invite-code co-op sessions for shared SQL and JSON code.

Added a dedicated Co-op sidebar tab in both the web app and the VS Code webview.

Moved collaboration to a production-safe shared room store backed by Redis-compatible REST.

Replaced fragile SSE delivery with polling-based event sync for stable Vercel deployments.

Code-First Collaboration Model

Reduced collaboration scope to shared code only so the ER diagram stays derived locally.

Each participant now keeps independent zoom, pan, and viewport control in the ER diagram.

Removed the broken invite-link action and kept the co-op flow centered on room codes.

SQLite .db Import and Export

Added direct browser-side support for `.db`, `.sqlite`, and `.sqlite3` uploads.

Schema DDL is extracted from SQLite files and rendered into the normal code + ER workflow.

Data previews now load from SQLite tables, and Export can generate a new SQLite `.db` file.

VS Code Extension Refresh

The extension now accepts SQLite files in addition to SQL, JSON, CSV, and Excel.

The webview shares the new co-op and SQLite handling from the main app.

Packaging metadata and marketplace copy now reflect co-op, SQLite, and release updates.
