Version Info – Server Health Monitor, PHP & MySQL Version Display, Environment Indicators
🛡️ THE ESSENTIAL TECHNICAL HUD FOR EVERY WORDPRESS PROFESSIONAL
Stop digging through hidden menus or leaving insecure phpinfo() files on your server. Version Info is the essential technical dashboard that brings your site’s most vital environment data directly into your daily workflow — the admin footer, the admin bar, or a dedicated dashboard widget.
Whether you’re a freelancer managing dozens of client sites, a developer debugging a complex plugin conflict, or an agency maintaining a portfolio of high-value properties, having instant access to your PHP version, MySQL version, WordPress version, and web server type is a mission-critical utility.
Version Info has been trusted by WordPress professionals since 2015 and is now supercharged with a complete PRO + Agency suite for serious site monitoring. Learn more at versioninfoplugin.com.

🎯 Real-World Use Cases
”The Support Hero” A client reports a bug. Instead of asking for their login credentials, you ask them to screenshot their admin footer. You instantly know their PHP version, MySQL version, WordPress version, and web server — without ever logging into their site.
”The WooCommerce Specialist”
Black Friday is coming. You use Database Tracking to monitor table size growth during the high-traffic event. When wp_options grows 300% overnight, you catch the autoloaded transient bloat before it takes down the store.
”The Agency Owner” You hand over a beautifully built site to a high-ticket client. With White-Labeling, the client never sees ”Gaucho Plugins” — they see your agency name everywhere. With Role-Based Visibility, the client’s editors see a clean dashboard without confusing server information.
”The Safety-First Developer” You manage staging and production environments for the same client. The bright red ”Production” badge in your admin bar prevents you from ever accidentally running a migration script on the live site. The admin bar highlight makes the environment unmistakable.
”The Managed Hosting Reseller” You run 40 sites on a Multisite installation. The Network Dashboard gives you a single page showing WP, PHP, and MySQL versions across every site — perfect for planning bulk upgrades. When a host updates PHP overnight, the Email Alert hits your inbox before the first support ticket arrives.
”The Remote Debugger” A client’s site throws a white screen. You open the Error Log Dashboard directly in wp-admin — no FTP client, no SSH terminal. The last 100 lines show a fatal error from a plugin update. The Version History tab confirms the plugin updated 10 minutes ago. Root cause found in under 60 seconds.
⚡ Performance & Architecture
Version Info is built with performance as the #1 priority:
- Transients API — All resource-heavy metrics (CPU, RAM, DB size) are cached. CPU/RAM uses 60-second TTL; database size uses 12-hour TTL.
- Heartbeat API — Live resource updates use the native WordPress Heartbeat, ensuring data refreshes only when the admin page is active.
- Provider Pattern — A
ProviderInterfaceabstracts all detection logic, making it trivial to add custom providers for AWS, Kinsta, or any host-specific API. - Hook-First Architecture — Every data point fires a WordPress filter (
version_info_wp_version,version_info_php_version, etc.) and every render point fires an action. Extend anything without editing core files. See the hooks reference. - Strict Typing — Every file uses
declare(strict_types=1)and PHP 8.1+ typed properties for maximum reliability. - WordPress Coding Standards — Follows WPCS, uses proper escaping, nonce verification, capability checks, and prepared SQL queries throughout.
🌍 Works With Your Stack
Version Info auto-detects and works seamlessly with:
- Hosts: Kinsta, WP Engine, Pantheon, Flywheel, Cloudways, SiteGround, and any standard LAMP/LEMP host
- Environments: Bedrock, Trellis, Local by Flywheel, MAMP, WAMP, Docker, DevKinsta
- Servers: Apache, Nginx, LiteSpeed, OpenLiteSpeed, IIS
