NitroPack

விளக்கம்

NitroPack is the all-in-one performance optimization service. It combines everything you need for a lightning-fast website. Image optimization, code minification, caching, CDN, lazy loading – you name it, NitroPack has it.

NitroPack performs all optimizations in the cloud. This makes it a very lightweight solution with a lower CPU overhead compared to standard caching plugins.

Our service provides you with the following (typically paid extra) functionalities included without the need for additional configuration:

  • Cloudflare CDN – we automatically serve your static assets from a CDN based on Cloudflare
  • Image Optimization – we optimize all of your images automatically and convert them to WebP
  • Cache Warmup – we keep your most important pages optimized at all times

Apart from these, NitroPack offers other unique features and benefits like:

  • Incredibly Simple Setup – getting started with NitroPack is a breeze. There’s no technical configuration or a 15-step installation process. And you don’t need to be a developer to set it up. Simply follow these 4 steps and you’ll be done in no time
  • No risk of damaging your original site files – NitroPack works on copies of your site files. You don’t like the results from an optimization? No problem. Purge your cache and start over. Even if you decide to disable NitroPack your site will go back to the state it was in before activating our plugin
  • Cache Invalidation – you can invalidate cache files instead of purging them. This allows NitroPack to keep serving your visitors from cache while a fresh copy of the cache is being generated in the background. Cache invalidation is awesome for high traffic situations like campaigns. It allows you to keep updating your site while still serving cache to your clients. And with NitroPack, cache invalidation happens automatically. (For more info on this, scroll down to the “NitroPack and Campaigns” section)
  • Critical CSS tailored to each of your unique layouts – most plugins that provide critical CSS functionality prepare a single critical CSS file per post type. Even when you have multiple pages with the same post type but different layouts. NitroPack detects this and generates unique critical CSS for each unique layout. Oh, and because desktop and mobile devices have different viewports, NitroPack also uses different critical CSS for each device type 😉
  • Optimize resources linked statically into your theme files – NitroPack will discover and optimize all resources linked into your theme, even ones that come hardcoded into your CSS files (even if they are multiple levels down an @import chain)

The configuration requires no technical knowledge. All you need to do is select your desired optimization level: Standard, Medium, Strong or Ludicrous. Besides that, NitroPack does all the work.

Running Marketing Campaigns with NitroPack

Two major issues often come up when running a campaign. First, each visitor hits your server with a unique URL request. Second, you lose your cache if you update content on your site.
Most optimization plugins come up short when it comes to both issues.
At the same time, NitroPack has two powerful features that help you thrive in these high traffic situations:

  1. NitroPack recognizes campaign parameters in the URL and ignores them when looking up a cache file for the campaign request.
  2. Cache invalidation – typically, when you update content on your site, caching plugins have to purge their cache and start rebuilding it. When a purge occurs during a high traffic period your visitors will no longer be served from cache. And your server will have to work extra hard to generate new cache files. As a result, the user experience on your website takes a hit. NitroPack solves this problem by invalidating the cache, instead of purging it. This method allows NitroPack to refresh the cache files in the background. At the same time, you still serve your clients from the slightly outdated cache files. As we already said, this happens automatically. You don’t need to worry about caching during an important campaign.

Whether you’re running a big campaign or your site suddenly becomes trending, both features are crucial for keeping your visitors happy.
So, if you want a fast website right now, go over to the Installation section and download NitroPack.

Incompatible Plugins

WordPress is designed to have only a single active page cache solution at a time, otherwise conflicts can arise. We do not recommend using NitroPack together with another caching plugin, like:

  • WP Rocket
  • Autoptimize
  • Swift Performance
  • WP Fastest Cache
  • WP Fastest Cache Premium
  • Powerpack (WPTouchPro)
  • W3 Total Cache
  • Breeze
  • PhastPress
  • WP Super Cache
  • Litespeed Cache
  • Swift Performance
  • PageSpeed Ninja
  • Comet Cache by WP Sharks
  • Hummingbird
  • SG Optimizer
  • WP-Optimize – only the page caching must be disabled, not the entire plugin
  • Smush – only the lazy load option must be disabled, not the entire plugin
  • JetPack – only the lazy load option must be disabled, not the entire plugin
  • ShortPixel – only the WebP conversion option must be disabled, not the entire plugin

3rd Party Services Used By The NitroPack Plugin

The NitroPack plugin acts as a service. It calls/sends data to our API servers, which perform all of the optimizations.
As a result, our infrastructure does all the heavy lifting. That’s how NitroPack ensures low CPU overhead for your servers.

NitroPack also uses Cloudflare and Bunny CDN to accelerate content delivery across the globe.

அடிக்கடி கேட்கப்படும் கேள்விகள்

Does NitroPack modify site files?

No. NitroPack works on copies of your site files. However, it does modify your wp-config.php file if WP_CACHE is not enabled yet.

I installed NitroPack but my pages are still slow. Why?

After installing and activating NitroPack, you must log into your account, go to “Connect Your Website” and use the provided Site ID and Site Secret to connect the plugin to our cloud service.

Why my scores are still low after connecting NitroPack?

After connecting NitroPack you need to select your desired optimization mode – Standard, Medium, Strong or Ludicrous. Once you do that, please visit your home page and allow NitroPack a minute to prepare an optimized version of your page. You can then run the tests again.

How long does it take for pages to get optimized?

It usually takes NitroPack a few seconds to optimize your pages.

Can I use another page caching plugin and NitroPack at the same time?

WordPress’s design allows you to use only one page cache solution at a time. Other page cache solutions are designed this way too. However, you can use other non-page cache optimization solutions perfectly well with NitroPack.io (e.g. database optimization plugins, object caching, etc.).

What if I have a question?

You can contact us anytime at https://m.me/getnitropack

Will NitroPack slow down my server?

No. We’ve designed NitroPack to be a very lightweight solution that adds no CPU overhead to your server.

I'm thrilled with the customer service I received.

The team is knowledgeable, very quick in responding. NitroPack is doing what it is meant to do, which is to improve the speed. Well done guys. Thanks

I thought the plugin was great. It does a really good job of increasing the speed of a website. This is true across all browsers, with the best experience on Firefox and mobile. Unfortunately, it did not work out for me, and I had to get a refund for the plugin. Since the servers are in Europe, it broke my mobile theme. Every time there was a change on the NitroPack side, my mobile site would start to display pricing in Euros, while my desktop website would still show my pricing in USD. I live in the USA, with 99% of my customers in the USA, so that was not working out for me. I advertise heavily with Google Ads and it was causing a lot of issues there and also confusion with my customers. This is why I gave the plugin four stars instead of 5. I also live in California, which has some strict privacy laws, and since I have no way to control my data flowing outside the USA, that was another deal breaker. Servers need to reside in the USA for me to be in compliance. If the company ever sets up servers in the USA, I think it would be a great plugin, and I would most likely return as a customer. Now, I am falling back on my SiteGround Optimization plugin that comes Free with the Siteground suite of WordPress tools. It is not as good as NitroPack, but a lot better than WP Rocket, and it is free.

This is probably the worst optimization plugin I have ever tried. Lately, I found some problems on a customer site. The header/slider image did not load properly. Nitropack prevented not only the image from loading but also the cookie banner from popping up. On paper, performance was awesome with a loading time of 260 milliseconds. Which is, of course, impossible when using the Enfold theme. And it did absolutely not FEEL like 260 milliseconds, but more that 4 seconds. After removing Nitropack, everything loaded propery, and the loading time "increased" to 1.4 seconds, which is a realistic value. Now, don't say: "Your settings were wrong!" This might be, but I exspect an optimization plugin to work properly out-of-the-box. So many cache plugins really make things worse, if you don't find the right settings. This is why I prefer "Cache Enabler". Yes, it is not as powerful as WP-Rocket, but it never fails. Just activate it, and you are good to go.

NitroPack is hands down the best caching plugin for WordPress + Elementor. It's super easy to set up and most of the time it's set and forget. But every now and then I need a bit of help. This is where the amazing support team comes in. They're super friendly and actually help solve the problem. This means I can focus on running my business not cutting my teeth as a WordPress developer. I highly recommend using NitroPack.

I've been struggling for a few months to achieve decent mobile speeds on my site. I'd tried WPRocket, Cloudflare (and Pro), Breeze and plenty of other plugins to improve speed. Despite lots of effort my web vitals on mobile were still poor. I tried NitroPack based on some SEO advice I paid for. I was highly skeptical, as my site has a huge variety of plugins (yea, I know, that's why I have such a performance issue). Much to my surprise, NitroPack transformed the performance of my most popular page, taking the total load time from 13 seconds to 5 on mobile. The scores on GTMetrix and Google Speed Test were transformed too. Second surprise - it didn't break any of my plugins Third surprise - once I paid for the premium there was some issue that meant my newly improved pages were not performing. I submitted a ticket on a Sunday morning and got a helpful response back from Antonia, one of NitroPack's support team, within 30 mins. I was a little hesitant having read that the support was poor. My experience so far is the exact opposite. NitroPack means I can now get on and focus on my content.
