Reviews

Developers and businesses worldwide rely on Uploadcare’s JavaScript File Upload Library for their file handling needs. Here is what our satisfied customers have to say about their experience with Uploadcare.

“In-house file infrastructure? No thank you. With Uploadcare, we save 40 hours of per week and decrease the total cost of ownership (TCO) on infrastructure development. More to ask?”

Yakov Karda
CEO & co-founder

“For us to build the functionality we use, it would probably take a team of 3 or 4 developers several months. Using Uploadcare, we've basically taken a shortcut. We haven't had to build any uploading or image-processing infrastructure ourselves, so we've saved a bunch of dev work. This part of our software is just handled. It's not something we need to worry about.”

Finbarr Taylor
CEO & co-founder

“Before using Uploadcare, I just did all the image processing myself with scripts. It was a nightmare. It’s a lot more work, and it’s not interesting work.”

Sergey Bliznetsov
Front End Architect

Initially, the implementation took about an hour. I integrate Uploadcare with all of my side projects now, and it takes minutes, especially with a Ruby on Rails site. Add the gem, place the helpers in the template, and I’m going. Today, it would probably take 10 to 20 minutes.
