Nginx Cache Purge Preload vs SpinupWP

NPP lets WordPress users manage Nginx Cache Purge and Preload (FastCGI, Proxy, SCGI, UWSGI) operations directly from the WordPress admin dashboard — actively warming the cache via site crawl, so your Nginx cache is always preloaded and ready. NPP is the only Nginx cache plugin that doesn’t just clear the table — it sets the whole banquet. No other Nginx cache plugin comes close to its feature list, purge architecture, preload intelligence on WordPress. 🖥️ Quick WP-CLI Manage your Nginx cache entirely from the command line. Perfect for automation, cron jobs, panels, and headless workflows.

Features 🧹 Purge All Nginx Cache: Completely clear all cached data stored by Nginx. 🔄 Preload All Nginx Cache: Warm the Nginx cache with the most recent data for the entire website. 🎯 HTTP Purge (ngx_cache_purge): When the Nginx cache module (ngx_cache_purge) is available, NPP uses it as the fastest purge path. Falls back gracefully to index and filesystem purge when the module is not present. 🗂️ INDEX Purge: Leverages the preload-generated URL → Filepath index to directly resolve and purge cache without filesystem traversal. If the cache exists and is valid, purge is executed immediately for near-instant performance. ⚡ RG Purge: ripgrep-powered cache file lookup that replaces slow PHP directory scanning for single-URL purges, enabling near-instant deletes on large or FUSE-mounted caches. Automatically falls back to standard scan if unavailable. 🚀 Auto Preload Nginx Cache: Automatically preloads the cache when Auto Purge is enabled for a POST/PAGE or after the Purge All action. 🧼 Auto Purge Nginx Cache: Purge cache on Post/Page content changes, comment status updates, theme/plugin updates, or when compatible Cache Plugins trigger a purge. Nginx cache is preloaded automatically if Auto Preload is enabled (for the entire site or individual page). 🔗 Purge Scope (Related Pages): Automatically purge related pages such as the Homepage, WooCommerce Shop page, and Category/Tag archives when a single URL is purged. Optionally preload those pages to keep the cache warm. 📡 Preload Feeds: Take full control of RSS/Atom feed caching. Decide site‑wide or per‑URL whether the main feed, per‑post comment feeds, and taxonomy RSS feeds are included in the preload process. ⏰ Schedule Nginx Cache Purge & Preload via WP Cron: Automate the purge and preload process using WordPress Cron jobs. 🧭 Proxy Support for Preload: Route preload requests through a proxy server for edge-case environments and containerized deployments. ⏱️ Live Preload Progress Monitoring: Watch the Nginx cache preload process in real time — complete with a dynamic progress bar, currently processed URL, 404 tracking, server load, and total completion time. 🌐 Remote Nginx Cache Purge & Preload via REST API: Remotely trigger cache purging and preloading through REST API endpoints. ⚙️ Manual Nginx Cache Purge & Preload: Allow manual purging and preloading of cache through the table view in the Advanced Tab. 📚 Nginx Cache Analyzer: Full HIT/MISS cache analyzer dashboard, from the last preload crawl with what is currently stored in the Nginx cache. Instantly spot uncached pages and Purge or Preload them directly in the Advanced Tab. 🪫 Preload All MISS: A targeted replacement for the expensive Preload All. Instead of purging and re‑caching everything (Preload All), it targets and populates only the cache entries that are not yet warmed. Perfect for sites with high cache coverage (>50%) where a full Preload All be wasteful. 🔍 On-Page Nginx Cache Purge & Preload: Manually purge and preload Nginx cache for the currently visited page directly from the frontend. 🗝️ Custom Cache Key Support: Define a regex pattern to parse URLs based on your custom _cache_key format. 📊 Monitor Plugin and Nginx Cache Status: Monitor plugin status, cache status, and Nginx status from the Status tab. 📈 Cache Coverage Ratio: Live gauge in the WordPress dashboard widget showing the cache coverage ratio, based on the last preload snapshot. Refreshable on demand without a page reload. ☁️ Cloudflare APO Sync: Automatically mirrors NPP purge actions to Cloudflare APO to keep edge cache synchronized with your Nginx cache. 🔴 Redis Object Cache Sync: Coordinates cache invalidation between NPP and Redis Object Cache during NPP-driven operations. NPP Purge All and Preload workflows handle Redis flushing at the appropriate stage to ensure both cache layers stay aligned. 🛒 WooCommerce Auto-Purge: Automatically purges Nginx cache when WooCommerce product stock quantity changes, stock status changes (in stock / out of stock / on backorder), or when an order is cancelled and stock is restored. 🖲️ WP-CLI Support: Manage Nginx cache directly from the command line. Purge and preload cache, view status reports, inspect logs, update settings, flush cache, and manage scheduled tasks without accessing the WordPress admin dashboard. 🔒 Concurrent Purge Serialization: Atomic lock mechanism prevents simultaneous purge operations from colliding, ensuring cache integrity during concurrent admin actions or background events. 🧩 Modular by Design: Easily integrate with external scripts and automation tools. 🖥️ User-Friendly Interface: Easy-to-use AJAX-powered settings, integrated into the WordPress admin bar and dashboard for quick access. 📋 Admin Notices and Logs: Receive notifications and view logs for plugin status and all cache-related actions within the WordPress admin area. 📧 Email Notifications: Receive email alerts upon completion of preload actions, with customizable templates to suit your needs.

This plugin ensures that the SpinupWP page cache is cleared when your site’s content changes. Not using SpinupWP yet? Sign up here. SpinupWP is a modern server control panel that’s here to help you implement best practices for every server you spin up. Designed for WordPress. This companion plugin should be installed on sites created using SpinupWP to allow the page cache to be cleared when your site’s content changes. Not using SpinupWP yet? Sign up here. Any Provider We support DigitalOcean, Linode, AWS, and any other provider. If your server has an IP address, you can connect SpinupWP. It does need to be a fresh install of Ubuntu though. Latest & Greatest Software SpinupWP will install the latest stable versions of Nginx, PHP, MySQL/MariaDB, and Redis from the standard apt-get repos. No who-knows-what-they-did custom builds of packages. Disconnect from SpinupWP in the future and you can still keep your packages up-to-date with apt-get upgrade. Automatic Security Updates SpinupWP will configure your server to install security updates as soon as they are available to reduce the likelihood of a software vulnerability putting your server at risk. Free SSL/TLS Certificates Serving your site over HTTPS is essential these days, not only for security, but to take advantage of the performance improvements of HTTP/2 as well. When you add a site to SpinupWP, a free Let’s Encrypt SSL/TLS certificate will be acquired, installed, and configured for your site. And SpinupWP will handle certificate renewals as well, so you hardly need to think about certificates. Cache All the Things One of the keys to a great performing WordPress site is caching. All sites are set up with Redis object caching to greatly reduce database requests. And with the check of a box you can enable full-page caching to serve pages lightning fast without even hitting PHP. Git Push-to-Deploy Developers! Developers! Developers! Add a git repository to your SpinupWP site and simply push to master to deploy your code. GitHub, Bitbucket, or a custom git repo will work. You can also configure a build script to run some tasks on the server after deployment is complete. Error Logs WordPress doesn’t enable error logging by default. Probably because the log is saved to a publicly accessible directory and can quickly balloon to take up a lot of hard drive space. SpinupWP enables error logs by default but stores them in a safe place and makes sure they’re rotated regularly like other server logs. Security Security Security Each server provisioned by SpinupWP is security-hardened from the word go. SSH login is disabled for the root user (you login with your user and use sudo instead). The firewall only allows connections to Nginx and SSH and failed attempts are monitored and blocked when the reach a threshold. Nginx is configured to defend against XSS, clickjacking, MIME sniffing, and other attacks. Software security updates are installed automatically. Scheduled Posts Published on Schedule For every site you add via SpinupWP, a server-side cron job will be configured to make sure that your WordPress site’s cron is executed every minute, as it should be. WP-CLI Preloaded If you love WP-CLI (we do! ❤) you’ll be very pleased to find it available on the command line the first time you login to your server. Security Isolation for Sites For each site that you add to your server via SpinupWP, a new system user is created for that site. All site files are owned by the site user and a PHP-FPM pool is configured to run as that user as well. Each site only has access to its files and so if only one site has a security vulnerability and gets infected with malware for example, only the files for that one site can be infected. SFTP Access for Your Clients If you’re hosting a site for someone else, you can easily give them SFTP/SSH access to just that site. And because of the security isolation between sites, they will only have access to files for that site. Professional Guidance & Best Practices SpinupWP will actively point you in the right direction and offer suggestions for maintaining your server. And because it provides detailed feedback about the operations it runs on your server, you can learn what is happening with your server. New release of Ubuntu just came out, should I upgrade? We’ll add a notice to the app about that, why we don’t recommend upgrading your existing servers, and how you can spin up a new server with the new release of Ubuntu and migrate your sites to that server instead. Should I install Varnish to improve page caching performance? We’ve benchmarked Varnish and Nginx FastCGI Cache performed better. Varnish would add complexity too, so one less moving part is another reason. Much of the time SpinupWP will suggest things that you may not have even thought of. Email deliverability for example. SpinupWP will strongly encourage you to configure an email sending plugin for the best email deliverability. SpinupWP’s guidance is especially helpful for those new to managing a server, but can also help those who’ve been at it a while, providing transparency to our decisions. Scheduled Backups of Site Files & Database All server providers (DigitalOcean, Linode, etc) offer automated backups of your entire server for a fee. These services are great and we highly recommend having backups of your whole server. But what happens if some media or data was deleted by accident from your WordPress site? You’re not going to restore your entire server just to get that data back. That’s where site backups come in. Site backups are full backups of your site files (media, themes, and plugins) and database. They allow you to easily restore a single site or just some files or data from a single site. With SpinupWP’s site backups, you choose your preferred provider to stash your backups whether that’s Amazon S3, DigitalOcean Spaces, or Google Cloud Storage. You plug in your account details and SpinupWP will send your site backups there in an easy-to-see format. Teamwork Makes the Dream Work Create a new team account, invite a member of your team, and allow them to spin up their own servers. Or just only allow them to add sites, the permissions you give them is up to you.
