Download Supabase JDBC Driver

What Is a JDBC Driver?

A JDBC driver is a Java library file (.jar) that enables Java applications to communicate with a database. The JDBC is a standard interface implemented by each database with a specific driver. Drivers are typically distributed by the database vendor or as open-source projects.

Understanding the JDBC URL

The connection parameters including the database location, database name and connection method are passed to the driver using the JDBC URL. The JDBC URL is a text starting with 'jdbc:...' which combines the hostname, port, database name, and any driver-specific parameters. The exact syntax can be different for each JDBC driver.

The Supabase JDBC Driver

Supabase is an open-source Firebase alternative built on top of PostgreSQL, providing a full backend-as-a-service platform with a hosted database, authentication, real-time subscriptions, and storage. It exposes the underlying PostgreSQL database directly, giving developers full SQL access and the ability to use any PostgreSQL-compatible tool. Supabase supports extensions such as pgvector for AI embeddings and PostGIS for geospatial data.

The Supabase JDBC URL

  • Required File(s): postgresql-xxx.jar
  • Java Driver Class: org.postgresql.Driver
  • JDBC URL: jdbc:postgresql://{HOST}:{PORT}/{DB}
  • Website: Supabase

Supabase provides both a direct PostgreSQL connection string and a connection pooler URL (via PgBouncer). For DbSchema, use the direct connection: jdbc:postgresql://db.xxxxx.supabase.co:5432/postgres?sslmode=require. Avoid the pooler URL for schema introspection as it may limit certain metadata queries.

DbSchema and Supabase

DbSchema connects to Supabase PostgreSQL using the standard JDBC driver, visualizing tables, Row Level Security policies, foreign key relationships, and pgvector extension columns, making it easier to design and document your Supabase database schema.

Explore Supabase Visually with DbSchema

Once the JDBC driver is configured, DbSchema connects to your Supabase database and gives you a full graphical workbench — no command-line required. Available as a free Community Edition and a full-featured PRO Edition. No registration needed to get started.

Interactive ER Diagrams

Reverse-engineer your Supabase schema into a drag-and-drop ER diagram. Arrange tables visually, add new columns, define foreign keys, and let DbSchema generate the DDL — all without writing SQL by hand.

Visual Query Builder

Compose Supabase queries by clicking on tables and columns — no SQL knowledge required. Add joins, filters, groupings, and aggregations through a point-and-click interface, then copy the generated SQL or run it directly against the live database.

Schema Synchronization

Compare your Supabase schema across development, staging, and production environments. DbSchema generates the exact ALTER statements needed to close the gap and lets you review every change before executing — reducing the risk of unintended schema drift.
