Gumlet Review

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.

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.

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.
