Screenshots

Requirements

• VS Code 1.83 or newer

OS/Platform Support

• Linux *(Linux-x64, Linux-arm64, Linux-arm, Alpine-x64)
• macOS (Darwin-x64, Darwin-arm64 Apple Silicon)
• Windows (Win32-x64)

Quick Start

• In a VS Code project using any of the supported databases, ensure your database is properly configured and accessible from your application code.
• For zero-config environments, DevDb automatically discovers and auto-loads your database. View your database by opening the DevDb view like in the screenshot shown, or by using the shortcut.

[!NOTE] DevDb also provides several Language and Framework Integrations

UI Actions and Key Map

• Cmd + K + D to toggle the view panel
• Cmd + K + G to go to a table
• Cmd + Click table name in the sidebar to open the table in the current tab
• Cmd + Click on a database value to edit it
• Click any value to preview it in the pane (useful for viewing prettified JSON string values)
• The right pane offers options to view the current table schema or selected value
• During edit sessions (activated during data edit/delete), the control box appears as shown in the screenshot
• During edit sessions: Cmd + Z to undo changes, Cmd + Y to redo changes, and Cmd + S to save changes
• Added new "Suggest New Feature" button

One-click Actions (Data Manipulation)

• Click the trash icon on a table row to delete it
• Click the Set null button on a database value to set the value to null

Supported Databases

Currently supported databases:

• SQLite
• MySQL
• MariaDB
• PostgreSQL
• Microsoft SQL Server

Loading Databases

DevDb can automatically discover and load your database using connection details from your VS Code workspace (zero-config mode). When this zero-config auto-discovery isn't available, a configuration file option is provided.

1. Zero-config (Automatic Database Discovery)

No configuration file is needed when the workspace root contains any of the following:

1. Applications managed by DDEV
2. Adonis using default .env config for MySQL and PostgreSQL (with Lucid ORM)
3. Django with settings.py for SQLite, MySQL, and PostgreSQL
4. Ruby on Rails with config/database.yml for SQLite, MySQL, and PostgreSQL
5. Laravel with default local SQLite database
6. Laravel with default .env config for MySQL/MariaDB, PostgreSQL, and Microsoft SQL Server
7. Containerized Laravel MySQL (Laravel Sail) with default .env/docker-compose.yml config (including dev containers support)

2. Config-based Database Loading

If zero-config support isn't available for your environment, create a .devdbrc file in your project root with your database connection details.

[!WARNING] Exclude the .devdbrc config file from version control by adding it to .gitignore. This protects sensitive information and allows team members to use different database configurations.

The configuration file should contain a single array of database connection objects. DevDb provides rich editing features for .devdbrc:

• JSON Schema Validation: Automatic configuration validation
• IntelliSense: Autocompletion for all fields, including type
• Snippets: Quick configuration templates:
• devdb mysql: MySQL configuration
• devdb mariadb: MariaDB configuration
• devdb postgres: PostgreSQL configuration
• devdb sqlite: SQLite configuration
• devdb mssql: Microsoft SQL Server configuration

Configuration File Example

[
	{
		"name": "My test MySQL database",
		"type": "mysql",
		"host": "127.0.0.1",
		"port": "3306",
		"username": "root",
		"password": "12345",
		"database": "test" // <-- the database to show in VS Code DevDb view
	},
	{
		"type": "sqlite",
		"path": "/path/to/database.sqlite"
	},
	{
		"name": "My MSSQL database",
		"type": "mssql",
		"host": "localhost",
		"port": "1433",
		"username": "sa",
		"password": "YourPassword123",
		"database": "master",
		"options": {
			"trustServerCertificate": true
		}
	}
]

Tools and Framework Integrations# Context Menu Entry

Open any database table in DevDb by right-clicking its name/model/entity from the editor in any framework/programming language.

Example from a Node.js app

Laravel## Eloquent Model Code Lens

DevDb provides Code Lens features for:

• Viewing the underlying table for the Eloquent model
• Generating a factory for the model (automatically pre-filled with real data from the underlying table)

[!NOTE] Factory Generation is also available via the context menu

Query Explainer

The Query Explainer integrates with MySQL Visual Explain to optimize SQL queries by analyzing MySQL's query execution plan. Usage:

1. Open a Laravel PHP file containing SQL query (Eloquent or DB facade)
2. Select the SQL query to analyze
3. Click the Explain query Code Lens or select Explain query from the context menu
4. View the explanation in your browser or copy the URL

[!NOTE] VS Code multi-root workspaces support is in development. Track progress here.

MCP Configuration

1. As shown in screenshot, click the hammer icon to copy the MCP settings.
2. In your IDE's MCP settings file (e.g. .vscode/mcp.json, windsurf/mcp_config.json, etc.), paste the copied JSON as one of the available MCP servers.

Your IDE/AI-tool should now be able to use your database details.

URI Handler

DevDb provides a custom URI handler that allows you to open specific database tables directly from external applications or links. This is useful for integrating DevDb with other tools or creating shortcuts to frequently accessed tables.

URI Format

The URI format follows this pattern:

vscode://devdb/open/table?connectionId=123&database=main&table=users&workspace=...

Parameters:

• connectionId: The ID of the database connection
• database: The database name
• table: The table name to open
• workspace: (Optional) The workspace path
