PixeBuilder is engineered to be lightweight and efficient. However, like any modern WordPress page builder, it relies on a specific server environment to function smoothly—particularly when handling complex layouts or importing prebuilt blocks. Below are the recommended system specifications to ensure optimal performance.
1. Server Environment
Since PixeBuilder runs on top of WordPress, your server must meet the core WordPress requirements.
-
WordPress Version: 6.0 or higher (Latest version recommended).
-
PHP Version: PHP 8.1 or higher (Optimized for modern PHP execution speeds).
-
Database: MySQL 5.6+ or MariaDB 10.1+.
-
HTTPS: Required for secure data transmission and modern browser features.
2. PHP Configuration Limits
This is the most critical section for page builders. If you experience "spinning loading screens" or "save failed" errors, it is usually due to these limits being too low.
| Directive | Recommended | Why it matters? |
| memory_limit | 512 MB+ | Prevents crashes when loading the visual editor. |
| max_input_vars | 6000 | Crucial for saving large pages with many blocks. |
| max_execution_time | 300s | Ensures imports of prebuilt blocks complete without timing out. |
| post_max_size | 64 MB+ | Allows for uploading larger media files and templates. |
| upload_max_filesize | 64 MB+ | Must match or exceed the file sizes you intend to upload. |
| wp_max_upload_size | 64 MB+ | WordPress internal limit; should match the upload directives above. |
| default_socket_timeout | 120s | Prevents timeouts when connecting to cloud servers for template imports. |
| suhosin | Disable | If this security patch is installed, ensure its limits are high or disable it to prevent conflicts. |
3. Client-Side (User) Requirements
For the best experience while editing pages with PixeBuilder:
-
Browser: Latest versions of Google Chrome, Firefox, or Safari.
Note: Microsoft Edge is supported, but Internet Explorer is not. -
Screen Resolution: 1280px width or higher (Desktop/Laptop recommended for building layouts).
-
JavaScript: Must be enabled in the browser.
4. Plugin Compatibility
PixeBuilder is designed to work efficiently with standard WordPress environments.
-
WooCommerce: Fully compatible (version 8.0+ recommended).
-
Caching: Compatible with WP Rocket, W3 Total Cache, and Autoptimize (clear cache after saving layouts).
-
General Compatibility: PixeBuilder is built to be compatible with virtually any third-party plugin that is well-implemented and follows official WordPress coding best practices.
Summary Checklist for System Admins
If you are asking your hosting provider to configure your server for PixeBuilder, you can copy and paste this request:
"Please ensure the server is running PHP 8.1+, the PHP Memory Limit is set to 256MB, PHP Max Input Vars is raised to 5000, and Max Execution Time is 300s. Please also verify that suhosin is disabled or configured not to block large POST requests."
