Running Multiple WordPress Sites Locally with DevKinsta

Why Run Multiple Local WordPress Sites?

Managing multiple WordPress projects simultaneously presents unique challenges for developers and agencies. DevKinsta provides a streamlined solution for creating and managing multiple local WordPress sites in isolated containers.

When building themes and plugins for WordPress, ensuring compatibility across different environments becomes essential. Developers often need to test their products against multiple PHP versions, WordPress releases, and configuration scenarios. A robust local development environment that supports multiple isolated sites eliminates the complexity of managing various configurations on a single machine.

DevKinsta addresses this challenge by creating containerized WordPress environments, where each site operates independently with its own PHP version, database, and configuration. This isolation ensures that changes made to one project do not affect others, providing a safe testing ground for development work.

For agencies managing client projects, this capability proves invaluable. Each client site remains completely separate, with independent configurations that can be tailored to match their specific hosting environments. Whether you're developing custom WordPress themes or building complex plugin architectures, having isolated development environments prevents unexpected conflicts and ensures consistent testing conditions across all your projects.

For teams working on WordPress plugin development, having multiple isolated environments allows testing plugins against different WordPress versions and PHP configurations without compromising the stability of other active projects.

Getting Started with DevKinsta

DevKinsta is a free suite of tools for local WordPress development created by Kinsta. The application provides a complete hosting stack consisting of PHP, Nginx, and MySQL, enabling developers to create local WordPress instances in just a few minutes. Unlike some development tools, DevKinsta remains freely available to everyone, not just Kinsta customers according to SitePoint's DevKinsta guide.

System Requirements

Before installing DevKinsta, ensure your local machine meets these requirements:

• Disk Space: Minimum 5 GB required, 20 GB+ recommended
• RAM: Minimum 1 GB required, 2 GB+ recommended
• Internet: Stable connection for initial download
• Virtualization: Must be enabled in BIOS

Installation Process

1. Download the installer from kinsta.com/devkinsta
2. Add your name and email in the download modal
3. Run the downloaded file (.dmg, .exe, or .deb)
4. Grant Docker Desktop access when prompted
5. Wait for Docker images to complete installation

When starting DevKinsta for the first time, Docker Desktop installs as a dependency. DevKinsta uses Docker for creating containerized WordPress environments. During installation, you may see a prompt requesting privileged access for Docker Desktop--provide your user account password to complete the setup according to SitePoint's DevKinsta guide.

For developers transitioning from other local development environments like XAMPP or MAMP, DevKinsta's containerized approach offers significant advantages. Each site runs in complete isolation, eliminating the common conflicts that arise when multiple projects share the same Apache or MySQL instance on a single machine. This architecture aligns with modern DevOps practices and provides a foundation for scalable development workflows.

Managing Multiple Sites Effectively

DevKinsta's interface provides comprehensive tools for managing multiple local WordPress sites simultaneously. The Sites list serves as your development command center, displaying all active projects at a glance according to Kinsta's official documentation.

Sites List Features

When viewing 10 or more sites, DevKinsta reveals additional organization controls:

The list shows key information at a glance, including WordPress version, PHP version, and site size for each project. Quick buttons provide immediate access to open the site in your browser or navigate to the site folder. The kebab menu (three-dot icon) offers additional options including site cloning and access to database management tools according to Kinsta's official documentation.

Organizing Your Development Portfolio

For agencies managing multiple client projects, effective organization is crucial:

• Naming Conventions: Incorporate client names, project types, or version numbers
• Filtering: Hide completed projects to focus on active development
• Resource Management: Stop unused sites to free system resources

Establishing consistent workflows across multiple local WordPress sites improves productivity and reduces errors. Consider implementing standardized development practices that work across all your DevKinsta projects, especially when your team follows agile development methodologies.

For developers looking to expand their WordPress expertise, understanding advanced concepts like actions and filters helps maximize the potential of isolated development environments for complex plugin and theme development.

Database Management with Adminer

Every DevKinsta installation includes Adminer, a lightweight database management tool similar to phpMyAdmin. Adminer provides a web interface for editing database tables, running queries, importing and exporting backups, and performing other database operations according to SitePoint's DevKinsta guide.

Accessing Database Tools

Click the Database Manager button on the Site Info page to launch Adminer. The tool opens in your default browser, displaying your WordPress database tables including wp_comments, wp_posts, and wp_options. Default WordPress tables appear in the Table column, with additional tables from plugins and themes also visible.

Common Database Operations

Editing Tables: Click any table to view and edit individual records. Modify site URLs, update plugin settings, or troubleshoot data issues directly. This capability proves valuable when troubleshooting configuration problems or making bulk changes that would be tedious through the WordPress admin interface.

Importing Databases: Supports both .sql files and compressed .sql.gz files. Click Import, select your backup file, and click Execute. This flexibility accommodates various backup formats from different environments, making it easy to migrate databases from production or other local development setups.

Exporting Databases: Generate backups with options for gzip compression and SQL format. Export before making significant changes to ensure you have restore points available. Regular database backups protect against data loss and enable quick recovery from unexpected issues.

SQL Commands: Execute complex queries directly, such as checking autoloaded data size or performing bulk updates across multiple records according to SitePoint's DevKinsta guide. This feature enables advanced troubleshooting and optimization tasks that go beyond standard admin interfaces.

Testing Email Functionality Locally

DevKinsta includes a built-in SMTP server and email capture tool that simulates email sending without delivering messages to actual recipients. Local WordPress sites can send outgoing emails like production sites, but all messages are captured for inspection according to SitePoint's DevKinsta guide.

Email Inbox Features

• Captured Messages: All outgoing emails stored locally
• Sender/Recipient Info: View from address, to address, and timestamps
• Content Inspection: Check body content and delivery details
• Display Modes: HTML, Plain Text, and Raw header views

Practical Applications

This capability proves invaluable for:

• WooCommerce Development: Test order confirmations and notifications without spamming customers
• Membership Sites: Verify welcome emails and subscription alerts during development
• Contact Forms: Ensure message delivery without accidentally spamming real addresses
• Notification Systems: Confirm automated communications work correctly before deployment

For e-commerce development projects, this email testing capability eliminates the risk of sending test orders or notifications to actual customers. Developers can verify that transactional emails, order confirmations, and notification systems function correctly in a completely isolated environment before deploying to production.

Deploying to Kinsta Staging

For developers with WordPress sites hosted on Kinsta, DevKinsta streamlines pushing local changes to staging environments. This integration eliminates manual export and import procedures when transferring work between local development and remote staging according to SitePoint's DevKinsta guide.

Push to Staging Workflow

1. Click Push to Staging on the Site Info page
2. Provide MyKinsta credentials if prompted
3. Select target site and environment
4. Confirm the deployment action

The process transfers your local site content to the chosen staging environment, overwriting existing content if a staging site already exists. After pushing completes, access your staging environment URL to verify changes. From there, promote staging to production using MyKinsta's standard deployment tools.

Benefits of This Workflow

• No Manual Exports: Direct transfer from local to staging
• Environment Matching: Staging closely mirrors production
• Efficient Testing: Verify changes before going live
• Version Control: Maintain clear deployment history

This streamlined deployment workflow reduces the potential for human error when moving between development and production environments. By integrating directly with Kinsta's platform, DevKinsta helps agencies maintain consistent deployment practices across all client projects.

Best Practices for Multi-Site Development

Resource Management

Running multiple containerized environments simultaneously consumes system resources. Monitor your computer's memory and CPU usage, stopping sites you're not actively developing. DevKinsta's site management interface makes it easy to stop and start individual environments without affecting others.

Docker Desktop allocates system resources for containerized environments. If multiple sites cause performance issues, adjust Docker's resource allocation in Docker Desktop settings. Increasing memory and CPU limits often resolves slowdowns when running many simultaneous sites.

Backup and Version Control

While DevKinsta sites exist locally, maintain regular backups of important work:

• Export databases before making significant changes
• Use version control for theme and plugin code
• Document each project's configuration and requirements

Documentation

Record for each project:

• PHP version in use
• Active plugins and configurations
• Any custom setup requirements
• Deployment history and changes

This information helps when switching between projects or troubleshooting issues after time away from a particular development effort. For teams practicing continuous integration and deployment, maintaining clear documentation ensures smooth transitions between team members and environments.

When developing custom child themes for multiple clients, maintaining organized documentation for each site's configuration becomes essential for long-term maintenance and updates.

Advanced Configuration Options

PHP Version Management

Different projects may require different PHP versions for compatibility testing or specific feature usage. DevKinsta supports PHP 7.2 through 8.x, allowing you to match local environments to production servers or test compatibility across versions according to SitePoint's DevKinsta guide.

When creating sites, specify the appropriate PHP version; existing sites can be recreated with different versions if needed. This flexibility enables comprehensive compatibility testing, ensuring your themes and plugins work correctly across the PHP versions your clients' hosting environments support.

HTTPS Configuration

Local HTTPS support enables testing SSL-dependent features without configuring actual certificates. DevKinsta generates self-signed certificates for local sites, providing realistic HTTPS environments for development. Enable HTTPS during site creation or configuration when your project requires secure connection testing.

For agencies developing secure payment integrations or membership systems requiring encrypted connections, this feature provides accurate testing conditions without the complexity of managing SSL certificates in local environments.

Multisite Installation

WordPress multisite networks require specific configuration during site creation. DevKinsta supports both subdomain and subdirectory multisite installations, enabling you to test network functionality locally before deploying to production. Select the appropriate multisite mode when creating sites that will function as networks.

This capability proves essential for agencies developing enterprise solutions or platform products that will support multiple sites from a single WordPress installation. Testing multisite configurations locally ensures proper network setup before deployment to client environments.
