Gumlet

Pros: It works and I like the concept of lazy load combined with exactly the size needed. I also like the many API-parameters you can use to size, crop, watermark, color-manipulate, ... the image.
They evolve rapidly and listen to the request of their customers.

Cons: The CDN worked reliable and fast as they used the Amazon CDN, but I have concerns about the future, as they switch now to their own CDN, which has only some nodes. But time will tell.
The rather new WordPress-Plugin needs still some work, but it's going into the right direction. Some things like css background-images were added just recently and do not work in all situation.

Overall: The service is easy to use and for it's complexity there is enough documentation too. It's a well thought through service which is new but in it's core already pretty matured.
If they keep up their recently rapid pace, I have high hopes for the future.
Good 4 Stars for now.

Pros: - Extremely easy to setup
- Support very fast and helpful
- Prices very affordable compared to other CDN's

Cons: Noting bad to say about Gumlet - even by trying hard.

Overall: Best experience in setting up and using a CDN I had, compared to other ones.

I am using Gumlet for my Magento shop - some other products I never got running or needed hours to get up and running.

With Gumlet it took me really just 2 minutes and it was done!

Pros: Absolutely the most affordable image optimization service.
Easy to install.
Multiple options of installation.
No need to upload images to their servers, system will do it on its own.
Support for serving css and js files.

Cons: Sadly you do not have the option to serve images on other buckets like Webflow. But it looks like that will be a features in the works.

Overall: I come from Cloudinary and this one service has saved me a lot of time and money. Google will now rate our website at 95% . Something amazing for any website out there. Hands down the best service service. Customer support is unprecedented.

Pros: Gumlet is one of our best investments, we are really happy with the speed of this Product. What we love about Gumlet is, it is not only limited to one platform like most competitors. Also, happy with their amazing Support.

Cons: Ability to edit subdomains with use, just in case a mistake was done, we can just edit it and not delete it and start over.

Overall: Really very happy with Gumlet, because we have seen a big difference in speed. We use to try out too many products that come in the market for website speed but we finally stick to Gumlet and are very happy using it.

Pros: - Extremely fast loading speed with CDN
- Allow Lazy Load
- Installation is very simple (just install their plugin into the domain cdn set, you already have 1 website with the fastest speed anywhere in the world)
- Extremely cheap price (only $ 5 for 25gb bw / month) I believe with current websites this package is more than enough for everyone). They have Free package with 1gb free, you can use it right now without any charge.
- Allow CDNs for both JS / CSS / Fonts through Cloudfront (this is an extremely good feature because I do not have to spend additional CDN costs for a 3rd service anymore, I can also immediately turn off the free package of Cloudflare (because to me Amazon Cloudfront is much better)
- Multi-platform support (they have their own API to deploy on your source code, I'm also integrating it on my website)
I recently learned that they have implemented a new CNAME feature that can help you create your own CDN sub domain name like cdn.yourdomain.com. This is great for saving and also making your website image more professional, or cooler.

Cons: I am still completely satisfied with Gumlet and feel that I don't have any weaknesses (or maybe I haven't realized it yet). Sometimes they will be able to answer support a little longer but that doesn't matter because all my questions are solved.

Overall: I got to know Gumlet when I was looking for a photo compression app but still kept the quality. With Wordpress, there are many plugins that can do this, but the image quality is reduced after compression or it is extremely expensive, some services are quite expensive and the number of images allowed to be compressed is very limited, while an image uploaded to wordpress can generate dozens of different sizes on its own.
That's why I have to choose an appropriate image compression application, in addition to good quality it should also have a CDN. We are in the era of global business, the website load through CDN is essential if you want everyone in the world can access your website quickly.

It was great that I found Gumlet. I wasn't sure at first, but they allowed the trial to try 1GB of bandwidth and it was amazing that I was completely conquered.

Pros: Overall a good package including the following features:

Custom Name
CDN
Appsumo Plan
Faster Websites

Cons: I don't have any cons although at the current pricing I may use an alternative particularly when there is a $5 per domain cost for C names but my legacy plan is exceptional value.

Overall: I am more than happy with this service I use, this and shortpixel on different sites and they compare well, I am always chasing the speed.

Pros: Was faster just not as much as hopped.
We still use it though.
Logo was making website render strange. Excluded image with supports help and now runs well.

Cons: Our website is faster and now with CNAME we have it all.
Support was great they helped me set up as I needed and was great and fast to talk with.

Overall: Our website is faster and now with CNAME we have it all.
Support is perfect.
Fast to reply to questions.
