Server Info – System Health & Diagnostics Suite vs Smush – Image Optimization, Compression, Lazy Load, WebP & CDN

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.

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.
