Browse your SeedBase projects, kick off data generations and pull SQL seed files straight into your workspace — without leaving the editor.
Features
SeedBase view in the Activity Bar: all your projects with their generations (status and date) at a glance.
Generate Data: start a generation for a project from the tree or the Command Palette and get notified when it completes.
Pull SQL into Workspace: download a generation as SQL, save it as seedbase-<id>.sql in your workspace root (or via save dialog) and open it in the editor.
Load into Database / Reset & Reseed: run a generation straight into your local database. Reset & Reseed truncates the project's tables first and reloads fresh data in one step (confirmation required).
Workspace DB auto-detect: the connection string is suggested automatically from .env / .env.local (DATABASE_URL), docker-compose.yml (postgres/mysql service) or prisma/schema.prisma — you only confirm or edit it.
Preview Data: open a generation as a read-only table (first 100 rows) in an editor tab — no leaving the editor.
Create Project / Push Schema: turn a workspace schema file (.sql, .prisma, Django models.py) into a new SeedBase project, or push schema changes to an existing project from the tree.
Seed Test Data: generate and load fresh data into your database in one command — handy before a test run.
Open in Browser: jump to the project's schema page on seedba.se.
Status bar entry: a SeedBase item in the status bar opens your projects when signed in, or starts the login when you're not.
Installation
Cursor, VSCodium, Gitpod, Windsurf and other Open VSX editors: search "SeedBase" in the Extensions panel, or run cursor --install-extension seedbase.seedbase. Also available at open-vsx.org/extension/seedbase/seedbase.
Plain VS Code (Microsoft build): download the .vsix from seedba.se/seedbase-vscode.vsix, then Extensions panel → ⋯ → Install from VSIX… (or code --install-extension seedbase-vscode.vsix).
Getting started
Open the SeedBase view in the Activity Bar (or click SeedBase in the status bar).
Click Login to SeedBase (or run SeedBase: Login from the Command Palette).
Your browser opens with a one-time authorization code. Confirm it while the extension waits.
Once authorized, the access token is stored securely in VS Code's Secret Storage (backed by your OS keychain) — never in settings or plaintext files.
Use SeedBase: Logout to remove the stored token.

Seeding before a test run
There is no dedicated tasks.json task: VS Code's shell task type cannot invoke an
extension command, so a generated task would be misleading. Instead, hang
SeedBase: Seed Test Data (generate + load) onto your own pre-test hook — for
example an npm pretest script that runs your seed SQL, or run the command from
the Command Palette before launching your test suite.
Configuration
The extension talks to https://seedba.se and stores your auth token in VS Code's
SecretStorage. There is no API-URL setting (a workspace settings.json from a cloned
repo could otherwise silently redirect your token). For local development against a
self-hosted instance, set the SEEDBASE_API_URL environment variable before launching
VS Code — an explicit, per-shell override that cannot be injected by a repository.
