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. Features Page cache purging Persistent object caching Ensures debug.log files aren’t saved in a publicly-accessible location

Your visitors decide to stay or leave in under 3 seconds. xSpeed Cache makes sure they stay. Most caching plugins bury you in settings, charts, and upgrade popups. xSpeed Cache does the opposite — install it, flip one switch, and your site loads faster. No bloat, no upsells nagging you, no PhD required. Built by the team at WPDeveloper — trusted by over 7 million WordPress users worldwide. What Does xSpeed Cache Do? xSpeed Cache is a full-site performance plugin. It caches your pages, shrinks your code, compresses your files, and serves everything as fast as your server physically can — including an AI-powered audit that tells you exactly what’s slowing your site down. The result: pages that load in milliseconds, not seconds. Better Google PageSpeed scores. Happier visitors. Better SEO rankings. The Speed Advantage No Other Free Plugin Offers When xSpeed Cache caches a page, it doesn’t just save it — it serves it directly from the server, bypassing PHP entirely. That means: With xSpeed static cache: 5–15ms response time Without it (PHP-served cache): ~85ms response time That’s up to 17× faster page delivery on cache hits. No other free caching plugin does this across Apache, nginx, and LiteSpeed automatically. Features at a Glance Page Caching Your pages are saved as static HTML files and served instantly to visitors — before WordPress even loads. The cache rebuilds itself automatically whenever you publish a post, switch themes, or update a plugin. You never have to think about it. Static-file rewrite path (bypasses PHP entirely — 5–15ms TTFB) Auto-purge on publish, update, comment, theme change One-click cache purge from the admin bar Exclude specific URLs (e.g. /cart, /checkout, /my-account) Set your own cache expiry (1–720 hours) Separate mobile cache for phone and tablet visitors Per-post cache rules — custom expiry or disable caching for individual posts Code Minification Strips all the unnecessary whitespace, comments, and characters from your HTML, CSS, and JavaScript without breaking anything. Minify HTML, CSS, and JavaScript Combine CSS and JS files to reduce HTTP requests Defer or delay JavaScript so it doesn’t block page rendering Async CSS loading Removes ?ver= query strings from asset URLs Safe-minify: automatically skips already-minified files and falls back if anything looks off GZIP Compression Makes every file your server sends smaller — so browsers download them faster. Auto-configures GZIP on Apache and LiteSpeed Shows a ready-to-paste config snippet for nginx and IIS Detects if your server already has GZIP active — no double-configuration Lazy Load Images, videos, and iframes load only when a visitor scrolls to them — not all at once on page load. Lazy load images, iframes, and videos Automatic CLS (Cumulative Layout Shift) fix so your layout doesn’t jump Fonts Optimization Web fonts are one of the most common causes of slow-loading pages. Adds font-display: swap so text is visible immediately while fonts load Preloads above-the-fold font files for instant rendering Removes the blank-text flash caused by slow Google Fonts responses Browser Cache Tells browsers to remember your static files (images, CSS, JS) so returning visitors load your site even faster. Sets proper Cache-Control and Expires headers Works automatically — no manual configuration needed Cache Preloader Warms up your cache automatically so the very first visitor after a purge still gets a fast page. Sitemap-driven cache warmer Auto-warms cache when you publish or update content Object Cache (Redis / Memcached) Speed up database-heavy WordPress installs with server-side object caching. Connect Redis or Memcached in seconds View status and flush cache from the dashboard CDN Support Serve your static files from a CDN for faster global delivery. Pull-zone URL rewriting for any CDN provider Built-in Cloudflare integration: connect your zone, auto-purge on publish, toggle dev mode Database Optimization A bloated database slows down every page load. xSpeed Cache keeps yours clean. Optimize database tables Remove post revisions, spam, trash, transients, and orphaned meta Schedule automatic cleanup so it runs on autopilot Disable Bloat Turn off WordPress features you don’t use — each one is a request your server doesn’t have to make. Disable dashicons on the frontend Remove oEmbed, RSS feeds, XML-RPC, jQuery Migrate, REST API authentication headers AI-Powered Site Audit (Pro) xSpeed Pro scans your specific site and tells you exactly which performance features will help the most — with severity ratings and concrete reasons, not generic advice. Smart Enough to Stay Out of Trouble xSpeed Cache handles the edge cases other plugins miss: Multisite ready — each site in the network gets its own cache and settings. LiteSpeed server? — xSpeed Cache detects LiteSpeed Cache’s server module and steps back to avoid conflicts. WooCommerce? — logged-in customers and checkout pages are never cached. WordPress Site Health — xSpeed Cache adds its own health check under Tools → Site Health so you always know your cache config is working correctly. Works on any server — Apache, nginx, LiteSpeed, IIS, and any standard PHP host. Designed for Everyone Non-technical users: A 3-step setup wizard walks you through first-time configuration in under 2 minutes. Settings auto-save — there’s no Save button to forget. Developers: REST API at /wp-json/xspeed/v1/, developer filters (xspeed_skip_minify, xspeed_cache_skip_for_post, xspeed_cache_expiry_for_post), WP_DEBUG awareness, and a React 18 + TypeScript admin UI under 80 KB gzipped. Agencies: Use the xspeed_branding filter to white-label the dashboard for clients. Private By Default xSpeed Cache never collects personal data, stores IP addresses, or uses tracking cookies. Every optimization runs locally on your server. By default it makes no calls to any third-party server — the only request is a quick check to your own site’s home URL to confirm GZIP is active, rate-limited to once per hour. xSpeed Cache also includes optional usage analytics. The setup wizard shows a clearly-labeled consent control for it (enabled by default, untick to opt out), and nothing is sent until you confirm your choices in the wizard. When enabled, xSpeed Cache shares anonymous, non-sensitive diagnostics — your WordPress & PHP version, active theme & plugins, server type, site language, and which xSpeed Cache features you have switched on — so we know what to keep fast and compatible. No personal data and no page content are ever sent, and you can turn it off again at any time from your dashboard. (See “External services” below.) Backed By a Team You Trust xSpeed Cache is developed by the trusted team at WPDeveloper, a leading WordPress marketplace used and loved by millions of users. Loved xSpeed Cache? If xSpeed Cache makes your site faster, please leave a review on WordPress.org — it really helps! External services xSpeed Cache contacts your own site (the gzip probe below); when usage analytics is enabled, an analytics service; only if you choose to submit the optional deactivation survey, that same service; and — only if you turn it on — one external performance-score provider. The setup wizard shows a clearly-labeled consent control for analytics (enabled by default, untick to opt out), and nothing is sent until you confirm your choices there. The deactivation survey is separate and never sends anything unless you explicitly click Submit. External scores are off by default and never run on their own. Self-hosted gzip probe What it does: Issues a single GET request to your site’s home URL (home_url('/')) with an Accept-Encoding: gzip header to detect whether your web server is already serving gzipped responses. The response body is discarded; only the Content-Encoding header is read. When it runs: On demand when the admin dashboard loads server status, throttled to once per hour via a transient (xspeed_gzip_active). Where the request goes: Your own site (home_url()). This request goes only to your own server. What is sent: No personal data, no site identifiers, no payload — just a standard HTTP GET from your server back to your server. Usage analytics (opt-in, off by default) What it does: When usage analytics is enabled, xSpeed Cache periodically sends anonymous, non-sensitive diagnostics to help us keep the plugin fast and compatible with real-world WordPress environments. Data sent: site URL, site name, WordPress version, PHP version, site language & charset, multisite flag, server software, your list of active & inactive plugins, active theme & version, text direction, and your xSpeed Cache feature usage (which optimization features you have switched on and their numeric settings — e.g. cache lifetime, minification, lazy-load). This is feature-usage data only: it tells us which features are actually used so we can focus on what matters. We never send any values you enter — no API keys, tokens, passwords, license keys, email addresses, URLs, brand names, or logos — and no page content, no visitor data, and no personal data (your email is never collected in the free plugin). When it runs: It runs at most once per day via WP-Cron, only after you confirm your choices in the setup wizard. Untick the consent control (or disable it later from the dashboard) and nothing is ever sent. Where the request goes: WP Insights, WPDeveloper’s usage-analytics service — https://send.wpinsight.com/process-plugin-data. (Privacy Policy) How to turn it off: Untick the consent control in the wizard, or disable it later from the xSpeed Cache dashboard. Opting out stops all data collection and clears the scheduled task. External performance scores (opt-in, off by default) What it does: Lets you run a performance audit of one of your own pages from the dashboard and shows the score alongside xSpeed Cache’s internal TTFB benchmark. Two providers are supported: Google PageSpeed Insights (works without an API key; you may add your own key to raise Google’s anonymous rate limit) and GTmetrix (requires your own API key — it has no anonymous mode). When it runs: Only when you press Test now on the dashboard, or run wp xspeed score run. There is no schedule and no background call. If the feature is left off — which is the default — no request is ever made. Where the request goes: Google PageSpeed Insights — https://www.googleapis.com/pagespeedonline/v5/runPagespeed (Terms, Privacy Policy) — or GTmetrix — https://gtmetrix.com/api/2.0/tests (Terms, Privacy Policy). What is sent: The URL you are testing (your own page, which the provider then fetches publicly) and, if you supplied one, your own API key for that provider. No personal data, no visitor data, and no site content are sent by the plugin. How to turn it off: Switch “Enable external scores” off in the xSpeed Cache dashboard (Health → PageSpeed). Past results stay in your database until you clear them. Deactivation feedback (optional, only when you submit it) What it does: When you deactivate xSpeed Cache, a short optional survey asks why, so we can fix problems and prioritize the right features. Nothing is sent unless you pick a reason and click Submit & Deactivate. What is sent: the reason (or reasons) you selected and any note you type. If usage analytics (above) is enabled, that reason is attached to your regular analytics report. If usage analytics is disabled, only a minimal message is sent — the reason, your optional note, your site URL, the xSpeed Cache version, and your WordPress & PHP version — and nothing else (no plugin list, no theme data, no personal data, no page content). When it runs: Only on the deactivation screen, and only when you click Submit & Deactivate. Choosing Skip & Deactivate, closing the dialog, or pressing Esc sends nothing at all. Where the request goes: WP Insights, WPDeveloper’s service — https://send.wpinsight.com/process-plugin-data. (Privacy Policy) How to avoid it: Click Skip & Deactivate (or close the dialog) instead of Submit — deactivation works exactly the same, with no data sent.
