Trustpilot Testimonials

I've been using the LiteSpeed plugin for my WordPress site, and I am absolutely thrilled with the results. The performance boost is incredible, making my site faster and more responsive than ever before. Pages load in the blink of an eye, and my visitors are noticing the difference.

But what really sets LiteSpeed apart is their exceptional support team. I encountered a few issues while setting up the plugin, and their support team was there every step of the way. They responded quickly, were incredibly knowledgeable, and went above and beyond to help me resolve every problem I faced. Their guidance was clear and effective, making the entire process smooth and hassle-free.

Thanks to the LiteSpeed plugin and its fantastic support team, my WordPress site is now running flawlessly. I couldn't be happier with the service I've received and highly recommend LiteSpeed to anyone looking to enhance their website's performance. Five stars all the way!

I reached out to support, and within hours, I was asked to help troubleshoot the issue I had. With the help of their support, I could fix the problem, which was a straightforward fix. The actual product brings so much value to my WordPress site and is effortless to use. Highly Recommend!

Primarily I am getting a near-perfect score in page speed insights! I also had a small issue regarding my mobile menu icon, not opening. I asked for help and got invaluable support from Ashok in good time [minutes].

Moreover, I could seamlessly integrate Cloudflare and QuicCloud for complete optimization easily. I am glad I am using Lightspeed!

I am

I already love their web server software openlitespeed. I had a funky issue and their top notch support staff fixed it quickly. Highly recommended. OLS is a great server to use if you run wordpress sites.

I've been using the plugin for website optimization that offers premium features like advanced caching at no cost. It doesn’t just cache your site; it also optimizes and converts images to WebP format, saving you a lot of time. Additionally, it includes page optimization features that go beyond just caching, making your site even faster.

The plugin also comes with a crawler feature that automates the caching process, which is a huge time-saver compared to doing it manually. However, be cautious if you're on a shared hosting plan, as the crawler can put a significant load on resources.

What truly stands out is the support team from LiteSpeed. They're incredibly friendly, responsive, and have a knack for diagnosing issues efficiently.

The best wordpress plugin for speed on the market. I am not very technical and wanted my site to be faster so I was recommended the LItespeed plugin from a lot of friends and even my hosting company recommended it.

My website was slow, but thanks to the litespeed plugin and all the excellent help I received from the team at litespeed my website is now very fast.

If you want your website to be faster which is very important for google ranking then you need the litespeed plugin.

I recently had the pleasure of working with Litespeed, and I must say, their performance left me thoroughly impressed. Here’s why:

Lightning-Fast Response: Litespeed’s speed is unmatched. Their solutions are delivered swiftly, ensuring minimal downtime and maximum efficiency. Whether it’s website optimization or troubleshooting, they’re on it in a flash. Crystal-Clear Problem Solving: When faced with technical challenges, Litespeed’s clarity shines through. Their team communicates solutions concisely, making complex issues feel like a breeze. No jargon, just straightforward answers. Adil: A True Asset: Adil, one of Litespeed’s team members, deserves special mention. His expertise and willingness to go the extra mile made all the difference. He’s not just knowledgeable; he’s genuinely helpful. In summary, Litespeed combines speed, clarity, and exceptional support. If you’re seeking a reliable partner for your web-related needs, look no further.

Kudos to Litespeed and a big thank you to Adil!

We have been using LiteSpeed for our WP website for quite some time now. And after correctly adjusting all the settings, the result is significant. We also use the QUIC CDN which generated significant improvements as well. Recently we ran into some issues with the crawler settings, but LiteSpeed Support, which was very willing and capable, didn’t stop until out issue was resolved. I would easily recommend it to anyone looking to improve their website performance.

I recently encountered a technical issue with my LiteSpeed server, and I reached out to their support team for help. The response was prompt, professional, and incredibly helpful. They guided me through each step with clear instructions, and their expertise ensured my problem was resolved quickly. The support team went above and beyond, making the entire process smooth and stress-free. I’m thoroughly impressed with their service and highly recommend LiteSpeed to anyone looking for reliable and efficient server solutions. Five stars well deserved!

I’m honestly shocked at how fast this system has made my server and all of my hosted sites. Previously, I set up all of my own caching plugins and not only did I fail to implement caching effectively, I frequently broke dynamic content. Litespeed has my system so well set up that I can downsize my server and probably cut my costs in half. I’m super grateful for the set up and all of the support. It took a little bit of adjustment, but man… super satisfying.

Litespeed is the best server platform available to ensure you have a super fast website. We have numerous websites hosting on the litespeed platform and cannot fault it. When an issue does arise the support is super fast and extremely knowledgable to fix any and all issues. If you are not on a litespeed enabled hosting account make the move today you will not regret it. Highly recommended.

Litespeed is an awesome free caching plugin. It will definitely help fix some speed and site issues. And I’ve personally only ever used their free version, and yet they’ve always been willing to provide great support whenever it’s needed. Thank you so much and please keep up the great work!

I am really impressed with Litespeed. It comes free with our hosting so we were able to cancel our paid plugin. It has drastically increased our web speed on 2 sites. After setting up I did have a couple issues. I set up a support ticket and was super impressed with the speed accuracy and follow up to make sure my issues were resolved both times.

I’m using the lightspeed cache plugin for my wordpress page, which is the best plugin I found that actually improves my pagespeed a lot in a quite easy way without completely messing up my website. I had a small issue though which I couldn’t fix, so I contacted the support. The customer-support-team replied really quickly, the reason for my problem was a little hard to detect but the team invested a lot of time to help me fix the issue. Also, they were really patient with me since I didn’t really know a lot about the issue and the different plugin settings and in the end, everything works fine now. Thanks a lot!

We switched from Nginx to LiteSpeed Enterprise. Nothing but a very happy experience! We are running WordPress websites, and they all work great. Their all-in-one solution is exactly what we need. Image optimization, CDN and dynamic caching. Amazing company, with amazing software, amazing caching speed, and most importantly: amazing support. Special thank you to Ashok and Philani. They helped a lot with their great customer service, expertise, and patience.

Exceptional customer support, very fast to respond and provide a solution. I’m extremely impressed and would highly recommend LiteSpeed to others. Also an incredible product, the WordPress plugin has everything you could possibly need. It’s superior in every possible way. Thanks very much to LiteSpeed and Adil for the fantastic experience.

Amazing service and support I decided to pay for the wordpress cache optimization product from LiteSpeed as I wanted to make sure everything was running as smoothly and fast as possible. The support was amazing. Sumith was my support engineer and he dealt with everything from the very start and having one person to speak with rather than many different engineers was very helpful and streamlined the process. I would highly recommend this service to anyone who wants their litespeed wordpress solution to be finetuned and healthchecked. Thanks again Litespeed and Sumith.

Great products & fantastic support! I’m very pleased that my hosting company is using LiteSpeed Server; their server and caching solution makes my website very fast and responsive. When I had an unexpected problem, their tech support really went above and beyond to help me. It was more than I would have ever expected and left a lasting, positive impression.

The web is still full of poorly engineered and optimised business websites, which is great news for anyone who knows what they are doing and why they are doing it. Like many small agencies, my reputation depends on the success of my business clients’ websites – when they’re successful, I am too. While there is plenty of nuance, the bottom line is this – speed = money, bookings, sales, and awareness.

I’ve tried every optimisation tool and technique under the sun (e.g. WP Rocket, ShortPixel, WPMU, etc) – but at the end of the day, I also need to be profitable, so my solutions need to be easily implemented, highly-effective, well-supported, and affordable. Since I started managing my own server farms, those things are important more than ever – and that’s what I got with LiteSpeed. It’s now a staple dev tool for speed and optimisation efforts – because it works. Yesterday’s site came up 100% for both mobile and desktop on Google PageSpeed, that’s no small potatoes. It was this site that I was working on all day yesterday when I ran into some difficulty with one issue. After a 14 hour day, I had all but given up on the idea of sorting before tomorrow when I sent out my SOS to LiteSpeed for input. I never counted on a reply so bloody quickly – less than 1 hour (after hours too), with a simple solution (of course), so I came back to implement it – that’s when I got my Google PageSpeed results – what a result!? Great timing, Jackson – a big thank you for that and the reason for my review today.

The bottom line: LiteSpeed isn’t a pretty face, but it does a bloody good job, and comes with all the bells and whistles a website needs to be successful online. I highly recommend them, obviously. And if you get stuck, don’t forget – ask for Jackon, he’s your man 😉

I use litespeed cache free version on my site… with real good speed enhancements

I had a technical issue causing text sixes on mobile and tablet views to vary.

I reached out to them and within the hour they solved it.

Pretty impressive…. Was expecting days

In today’s world where new technologies spring up like mushrooms after the rain, it is very difficult to stay on top. One of the essentials of large IT companies is their technical support. In my 25+ years in the IT business, I’ve been in some sort of contact with technical support staff almost every day. I have no words to describe the pleasant response I encountered with the support of LiteSpeed Technologies, and not only that, but great knowledge can be seen and felt in every sentence. And I also have to add that agility is in development where fixes are incorporated in a very short time frame (read same day) and become official as a final product. And you also submit the same in cooperation with other companies that use their products and services.

The essence of all of the above comes from a great expert who adorns such a serious company and I would be remiss if I did not mention his name, which is Eric. I hope that Eric will be an example to other companies of how to run their business, and what kind of people should be employed in such places. Many thanks once again!!! Dragan P. Lead Stack Developer of Coral

This company with its software is the best i ever used! The support is awesomeeeeee and available in seconds. The support guys will try to solve your issue until it’s solved even if the issue is not directly related to the litespeed. I find it world class!
The software and the technology is also easier to use and has the best performance and provide the best results for your web infrastructure!!

I am really happy to use Litespeed and i will definetely recommend to everyone around me and use it to any of my current project and future project !

Thank you Litespeed !

When you think of reliable servers, fast like no other and without security problems, you think of LiteSpeed. We have spent years of a combination between Cyberpanel + LiteSpeed Enterprise that has only brought us the best of experiences: practically not intervening in the servers other than to update. Downtime? I don’t even know whats that. 😉
