I have been using it for years as a service to deliver photos to the end-user. I must say as a photo hosting, it works great. I recently started using the API option to optimize the photos that are on the website and I like the simplicity, but I still haven't quite measured the speed at which the service optimizes the photos. I am generally satisfied with the functioning. They are constantly improving, following trends, and trying to follow the requirements that, above all, Google imposes.

If you have photos on the site that need to be adjusted so that they load faster, all you need to do is install their WP plugin and everything will be optimized. That's it, in one click. On the other hand, there is the option of uploading directly to the Imagekit control panel and then linking on the site with that target external source.

I will love for the service to inform me what to choose or do, to get more optimized image delivery. In options, there is fixed value to choose but I will love for it to have more flexibility and to automate the delivery based on what is known.

We'been using ImageKit for faster image delivery through an Image CDN, better image processing (smaller file size), cache for dynamic URLs. Much faster page load, happier clients. Specially in mobile/3G connections, this is much more noticeable.

Endpoints connected to non-static image sources. This enables us to do some really cool & fast dynamic image generation. Without Imagekit, our dynamic images would be not very performant, which leads to an overall slower website experience.

It's not so easy to understand where are we using all our bandwidth within ImageKit. ImageKit dashboard provides have a monthly view with the highest consumption resources, but as we try to adjust things, it's hard to see if they're working until the next month.

painless format conversion and thumb generation.

The transition from an existing S3 bucket with lots of assets was easy. We needed an auto rotation feature (based on EXIF data) and it was implemented very quickly from their team.

So far so good. The flat rate is interesting but actually a bit expensive for our needs. We run an application used by university and some period (holidays, semester breaks) have a very low activity.

Went through various alternatives such as Cloudinary, Fastly, etc and while they have a great product, their documentation was difficult to sort through. It took a while to get up and running, whereas, Imagekit was very easy to use.

Easy to use documentation, timely blog articles, intuitive user dashboard, and fantastic product.

Nothing I can think of yet....they do great in everything!

The experience with imagekit has been outstanding. Even though the documentation is very well written with many code examples, we still had some questions and whenever we asked a question via the Intercom widget on their website, we got a competent reply from an actual engineer within minutes. Even better, we found one or two bugs, reported them, within minutes we were given a workaround AND within a day, they had pushed a bugfix. This blew my mind. This company is agile and moves fast.

Imagekit is incredibly easy to setup. If you have an S3 bucket on AWS, you are basically good to go. We just had to change 5 lines of code in our backend to return the new image URLs, and we were all set.

In the beginning, we weren't able to use our debit card. Now they use Stripe and recurring payments are no longer an issue. No cons for us.
