Generate test data in VS Code

Why generate test data inside the editor

• No context switch: stay in the file you are testing, run a command, get loadable data.
• The data is foreign-key-consistent: every customer_id points at a customer that exists, so it loads with constraints on.
• Pull straight into your repo as SQL, CSV or JSON, then load it into your dev database or fixture folder.

Install

Install from your marketplace of choice. The extension is the same across VS Code and Cursor.

• VS Code Marketplace — search "SeedBase" in the Extensions panel.
• Open VSX — for Cursor, VSCodium and other open builds.
• Download the VSIX — then Extensions: Install from VSIX… in the Command Palette.

From schema to data in four steps

1. Open the Command Palette (Cmd/Ctrl+Shift+P) and run SeedBase: Sign in. It opens the browser once to link the editor to your account.
2. Run SeedBase: Generate and pick a project. SeedBase builds a foreign-key-consistent dataset from that schema.
3. Run SeedBase: Pull and choose the format, SQL, CSV or JSON.
4. Load the SQL into your dev database, or drop the CSV/JSON into your fixtures. Done.

Your account, projects and row limits are the same ones you see at seedba.se. Build a schema there from a SQL dump, Django models or a Prisma schema, then drive generation from the editor.

Works with your stack

• Editors: VS Code and Cursor. There is also a JetBrains plugin for IntelliJ, PyCharm, DataGrip and the rest.
• Databases: PostgreSQL, MySQL, MariaDB, SQLite, SQL Server. Export SQL, CSV or JSON; Pro pushes straight into the database.
• Schemas: import from a SQL dump, Django models, a Prisma schema, or a live connection.
