Why do you need a Performance Optimization Plugin?

A high-performing website significantly contributes to a better user experience, higher SEO rankings, and improved conversion rates.

Performance optimization plugins like NitroPack help you improve the speed of your website, pass Core Web Vitals, and remain competitive in a rapidly-evolving web space.

While numerous performance optimization plugins are available, a select few consistently stand out. Don’t be fooled by the packaging, though. NitroPack might be part of the WordPress plugin directory but after installation, it comes apparent it’s a full-blown SaaS that operates entirely on the cloud.

Let’s explore the distinctive features that made NitroPack an outstanding solution on the optimization market.

NitroPack Features

Core Web Vitals Optimization

NitroPack effectively addresses performance and speed. In the past, the plugin has been criticized for a one-sided approach to optimization, written off as a tool that improves speed but does little for real-world performance.

However, data speaks volumes and we went straight to the source to check where NitroPack stands in terms of passed Core Web Vitals.

The global Core Web Vitals Technology Report (CrUX) shows the clear leader of % of users passing Core Web Vitals – NitroPack with 40.74%.

Along with an advanced resource loader, it uses 35+ powerful optimization features that work on autopilot to properly prepare your website for interactions with real users. NitroPack runs on an enterprise-level cloud infrastructure to take the load off your servers and provide a lightweight solution WordPress websites are dependent on.

HTML, CSS, and JavaScript Optimization

Excessive code can often slow down your website. NitroPack tackles this issue through minification, compression, deferring, and smart combining of code that effectively reduces the size of your HTML, CSS, and JavaScript files by removing unnecessary characters like line breaks, whitespace characters, and comments, without changing their functionality.

Image Optimization

What other plugins provide as a separate service, NitroPack offers out-of-the-box.

The plugin’s image optimization stack is nothing short of impressive with Preemptive Image Sizing, WebP Support, Adaptive Image Sizing, Lazy Loading, Lossy and Lossless Compression, and more.

It’s a powerful toolbox that ensures images above and below the fold are loaded with the correct priority, significantly improving page load times and the overall responsiveness of your web pages.

CDN & Caching

NitroPack offers a built-in Content Delivery Network (CDN) by Cloudflare with GZIP and Brotli compression to serve your content from servers close to your site’s visitors, enhancing the delivery speed.

Moreover, its intelligent caching system ensures that your website’s static content is served instantly, further boosting performance and your visitors’ browsing experience.

Font Optimization

NitroPack’s font optimization specifically targets web fonts, which can impact your website’s load time due to their file size or if the browser needs to make an extra trip to a third-party server to fetch them.

Here are some key aspects of NitroPack’s font optimization:

  • Font Preloading: NitroPack automatically identifies and preloads critical fonts. This way, the browser knows which font files are important for rendering the page and it can start fetching these files as soon as possible. Preloading helps minimize the Flash of Unstyled Text (FOUT) or Flash of Invisible Text (FOIT) effect.
  • Font Subsetting: An innovative feature available for the Scale subscription only, this technique reduces the size of the font files that your website needs to load. Essentially, font subsetting involves removing unnecessary characters from a font file, thus reducing its size and making it quicker to download and render.

ECommerce Cart Cache

ECommerce Cart Cache is a caching feature that enables fast browsing in a WooCommerce store with items in the cart. In other words, all online shoppers can add items to their cart without affecting the load times of a web page. As a result, all eCommerce owners can expect an increase in purchase value.

NitroPack Pricing: Is it Worth the Investment?

NitroPack differentiates between monthly and yearly subscriptions.

Their paid plans start from $21/month and go up to $176/month based on the number of resources your website might need. A free plan is available with limited resources for testing purposes.

Upon request, NitroPack assembles a highly-flexible custom plan to answer the different needs of agencies, publishing businesses, enterprises, and digital creators with multiple websites.

All NitroPack tiers are based on:

  • The number of monthly visitors your website receives
  • The monthly CDN resources your website needs
  • Plan-specific advanced features

Each tier brings additional benefits as your site grows.

Why NitroPack subscriptions cost more than what you’d expect?

The way I see it, NitroPack invests heavily in offering a full-fledged service that goes beyond the quality you would get with a one-time purchase. By becoming a NitroPack subscriber you get ongoing treatment that includes support, access to new features, the latest in Google’s Core Web Vitals, and more.

Another upside is the elimination of manual updates after new releases and decreased costs due to outsourcing the heavy lifting to NitroPack’s infrastructure.

Before purchasing a premium plugin, checking out customer reviews is always advisable.

The record shows NitroPack dedicated significant resources to build a robust technical support team with trained performance optimization experts. Today, NitroPack offers 24/7 support to its users and it’s not an exaggeration to say 9/10 people recommend the plugin for its fast, reliable support.
