Performance Lab
The Performance Lab plugin is a collection of features focused on enhancing the performance of your site, most of which should eventually be merged into WordPress core. The plugin facilitates the discovery and activation of the individual performance feature plugins which the performance team is developing. In this way you can test the features to get their benefits before they become available in WordPress core. You can also play an important role by providing feedback to further improve the solutions. The feature plugins which are currently featured by this plugin are: Embed Optimizer Enhanced Responsive Images Image Placeholders Image Prioritizer Instant Back/Forward Modern Image Formats Optimization Detective (dependency for Embed Optimizer and Image Prioritizer) Performant Translations Speculative Loading View Transitions (experimental) These plugins can also be installed separately from installing Performance Lab, but having the Performance Lab plugin also active will ensure you find out about new performance features as they are developed.
Server Info – System Health & Diagnostics Suite
Server Info provides a practical dashboard for inspecting the hosting environment behind a WordPress site. It brings important WordPress, PHP, database, caching, certificate, and diagnostic details together without changing the public site. All diagnostic features are free. The optional Support area offers one-time voluntary payments through Freemius; paying does not unlock or restrict plugin functionality. Overview and diagnostics Server hostname, IP address, protocol, operating system, web server, and resource usage. SSL/TLS issuer, hostname, expiry date, and remaining days, with graceful unavailable states. Optional domain registration expiry and registrar lookup, disabled by default. PHP version, limits, extensions, configuration summary, and a detailed phpinfo view. Database version, size, charset, collation, limits, and largest tables. WordPress version, memory, debugging, permalinks, theme, and plugin status. OPcache, Redis, Memcached, object cache, and output buffering detection. Configuration, file permission, cron, and error-log diagnostics. Administrator controls Optional admin bar environment HUD. Compact optional admin footer summary. Display schemes and custom background/text colors. Settings for external domain-expiry lookup and admin display elements. The dashboard and HUD are available only to users with the manage_options capability. External Services Server Info includes the Freemius SDK for optional usage opt-in and voluntary one-time supporter payments. Freemius communication is subject to user consent where requested by the SDK. The checkout script is loaded from checkout.freemius.com only after an administrator selects a support amount. See the Freemius privacy policy and terms. The optional domain-expiry setting is disabled by default. When enabled and an administrator opens the dashboard, the plugin sends the site’s registrable domain to an HTTPS RDAP service operated by the relevant registry or rdap.org. If RDAP cannot provide a result, it may query the relevant public WHOIS server over port 43. These services use the domain name to return public registration data. See the RDAP bootstrap service, RDAP.org, and the applicable registry’s terms and privacy policy. The SSL/TLS certificate check connects from the WordPress server to the site’s own hostname on port 443 to read the public certificate. No visitor data is sent.
