Click a table node to inspect columns.

A SchemaSpy-style ER diagram, right in your browser

No Java install, no local SchemaSpy setup. Upload a .sql DDL file, or connect a saved Snowflake account, and get an interactive, searchable entity-relationship diagram you can pan, zoom, and click through — the same core value as SchemaSpy, delivered as a free web tool.

How it works

  • Upload or connect: Choose a local .sql file, or pick a saved Snowflake account / database / schema for a live connection.
  • Diagram rendering: Tables and foreign-key relationships are rendered as an interactive graph you can pan and zoom.
  • Search & focus: Filter the sidebar table list by name and tick checkboxes to narrow the canvas to just the tables you need.
  • Inspect: Click any table node to slide in a details panel with its full column list, types, and keys.

FAQ

Is this a SchemaSpy replacement? Yes — it gives you the same core value as SchemaSpy (a browsable, visual ER diagram of your schema) directly in the browser, with no Java install or local setup.

Can I connect a live Snowflake database? Yes — switch to the Snowflake tab, pick a saved account, database, and schema, and load the live ER diagram directly.

Can I focus on just a few tables? Yes — use the table list checkboxes and search filter to narrow the diagram down to only the tables you care about.

Does it support other databases besides Snowflake? Any SQL dialect works via file upload (Postgres, MySQL, SQL Server, Snowflake DDL). Live database connection currently supports Snowflake.
