Features

MCP Server: Provide your database information to AI-powered IDEs and MCP clients like Cursor, Windsurf, etc.
Quick table open command: Press Cmd+K Cmd+G (Mac) or Ctrl+K Ctrl+G (Windows/Linux) to quickly open any table.
Zero-config Database Auto-discovery: Automatically discover and load your database ― no manual configuration required. Supports environments like DDEV, Adonis, Laravel, containerized setups (Laravel Sail), etc.
Database affordances for Local Development: Because of a deep understanding of your database schema, DevDb is able to provide affordances that aid development and debugging, such as one-click generation of Eloquent Model factories, etc.
Powerful IDE Integrations: DevDb nicely integrates your database with your IDE to provide very useful IDE-powered features like Context Menu & CodeLens Integrations directly in your editor, providing features like opening tables from code, invoking SQL query explainer when working on query optimization tasks, etc.
Rich Database Client with Intuitive UX: Dedicated database client view with one-click data browsing, inline editing, deletion, one-click reconnection, etc. Easily modify, set values to null, preview complex JSON data, all within a responsive interface.
Data Export: Export table data as well-formatted JSON or SQL INSERT statements copied to your clipboard or saved to file.
Comprehensive Multi-database Support: Seamlessly interface with SQLite, MySQL, MariaDB, PostgreSQL, and Microsoft SQL Server; with more to come!
Intuitive Configuration System: In environments where automatic zero-config is unavailable, DevDb provides quick snippets that produce well-formatted templates, as well as JSON Schema validation IntelliSense, which altogether makes creating configuration file for connecting to your database an awesome experience.
Integrated Framework & Tool Support: Tailored support for popular frameworks and tools including Laravel, DDEV, and Adonis ensures a seamless development experience. Need special feature(s) for your environment? We're listening!.
Cross-platform Compatibility: Engineered to perform consistently on Linux, macOS, and Windows, ensuring maximum flexibility as you can carry on your work across all these platforms.

Requirements

VS Code 1.83 or newer
A VS Code project using any of the supported databases

OS/Platform Support

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

<small> Ubuntu 20.04 (including equivalent distors) and below are not supported because they have reached EOL and no longer supported runners in GitHub Actions. See https://github.com/actions/runner-images/issues/11101 </small>

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:

Applications managed by DDEV
Adonis using default .env config for MySQL and PostgreSQL (with Lucid ORM)
Laravel with default local SQLite database
Laravel with default .env config for MySQL/MariaDB, PostgreSQL, and Microsoft SQL Server
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"
	}
]

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:

Open a Laravel PHP file containing SQL query (Eloquent or DB facade)
Select the SQL query to analyze
Click the Explain query Code Lens or select Explain query from the context menu
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

As shown in screenshot, click the hammer icon to copy the MCP settings.
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:

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

Parameters:

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