Wanna Drop Ranking Use Nitropack?

By Ameer Hamza (hamza1999) on February 24, 2025

Using nitropack from past 2 years. They should update thier things. This plugin is not working anymore and their support system is also not as before not helping not replying.

Will NOT work without connecting to Nitro servers - do not recommend.

By John Chapman (jcchapster) on February 5, 2025

This plugin will NOT work standalone.
It requires connection to the Nitro servers.

I do not recommend.

It's pity that there is no free version.

By Jerzy Pazurek (jurekpazurek) on November 25, 2024

Plugin has only paid version.

Slider Revolution Not Working

By Roald Moy (roaldmoy) on November 15, 2024

Slider Revolution sopped working after enabling Nitro.
Have no idea how to make it work, or by disabling cache for the slides.
Got some feedback long time ago, but that did not work.
Give 1 star because without the slides, the page is pretty useless.

Impressive Performance Optimization

By Jimmy90 (herbashake90) on November 6, 2024

I’ve been using NitroPack for over 3 years now, and it has consistently improved my site's performance and loading speed. It’s easy to set up, and the results are noticeable almost immediately. Whether you're looking to enhance site speed, boost SEO, or improve user experience, NitroPack is a fantastic tool. Highly recommended!

If you are smart you buy it now when its black friday deals in november ;)

Best plugin for Website Speed optimization

By Arslan Khursheed (arslankhurshiidofficial) on October 9, 2024

Great for best optimization scored on page speed insight. Recommended.

Puts links on the frontend!

By George Kpax (gkpax) on October 9, 2024

I can't believe this plugin has not been moderated yet. It clearly violates the rule "10. Plugins may not embed external links or credits on the public site without explicitly asking the user’s permission." from the official Plugin Guidelines.

All “Powered By” or credit displays and links included in the plugin code must be optional and default to not show on users’ front-facing websites.

Avoid.

Best optimizer out there by far

By shayeryan on July 26, 2024

I've used em all. This one is the easiest to setup and just freakin works!

Beware | Malicious User Agent

By Generosus (generosus) on July 13, 2024

After removing this plugin, NitroPack's servers continue to ping (i.e., attack) our website for information via the malicious user agent, Nitro-Webhook-Agent. Confirmed with the developers of this plugin via support topic.

If you have used this plugin in the past and no longer need it, we highly recommend blocking the following:

User Agent: Nitro-Webhook-Agent
IPs: 46.101.77.196, 159.65.180.53, 178.62.81.205

Just awesome

By aderjanos on June 22, 2024

Bought the plugin after trying wp-rocket+rocketCDN and after trying a combination of free plugins and manually optimizing my site.
So far this has been the best experience and has given me hope that having an online store on wp+woocomerce is not a lost cause.
Wp-rocket had recurring issues: load times were uneven and this showed in the pagespeed insights console too. Main page loaded in okay time, but single product pages took forever and the load experience was bad (page hanging for 5-10s on occasion). The issue persisted even with rocketCDN too. I spent lots of evenings trying to figure out how to fix it. wp-rocket updates were also causing havoc and had unexpected good/bad effects on load times.
With nitro the loading experience is a lot better, they optimize the site really well, it's truly lazy loaded, served through a good CDN network, load times are consistent. I am really pleased - i don't get the cold sweats when I think about what my customers are experiencing when browsing the site. It's a big relief. I hope they keep up the good work.
Most of the one-star ppl are complaining about the banner in the free version - although it's clearly explained on the plugin page.

Try other plugins too!
