About DB Schema Viewer
When a schema spans dozens of tables, scanning raw DDL to find a particular column or relationship gets exhausting fast. The DB Schema Viewer organizes your schema into a browsable structure, letting you explore tables, columns, types, and relationships without scrolling through endless statements. It turns a flat dump of definitions into something you can navigate and actually inspect.
Load your schema and the tool presents it in a clear, structured view so you can drill into the parts you care about. Everything happens in your browser with no signup and no watermark, and your schema details never leave your machine. It is a fast, private way to get oriented in a database, whether you are reviewing your own design or making sense of one handed to you, all without a desktop database client.

FAQ
What do I need to provide to view a schema?
You supply your schema definition and the viewer parses it into a structured, browsable layout of tables and columns.
Can it browse a live database connection?
No. It works from the schema you provide rather than connecting to a running database, which keeps credentials out of the picture.
Does it show column types and relationships?
Yes. The structured view surfaces columns, their types, and the relationships defined in your schema.
Is my schema kept private?
Yes. Parsing and display happen in your browser, so your schema never leaves your machine.
Can I use DB Schema Viewer on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
