27 Large Companies using Ruby/Rails in 2023

I frequently get asked why we use a Ruby stack over other “newer & better” stacks. I've heard suggestions to “upgrade” our stack but I’ve stood by Ruby for years as our primary tech stack in all the projects we have worked on. From startups with just a few visitors to complex platforms serving millions of requests.

Unless we are talking about a very specific use-case, the programming language and the framework you choose is mostly irrelevant for web platforms. The decision mostly comes down to preference (in my opinion), experience someone has with it, how invested they are in that language’s community and how many people they believe they can hire to expand the team. Disagree? Tweet to me!

At this stage you’re probably saying, “Daniel, that seems like a bold claim to make. Who else even uses Ruby?”.

Everyone loves social proof. Every time someone has asked me why I’ve chosen Ruby, I usually just point them to others who use it. Several popular platforms that we use are built on Ruby - keeping the Ruby community strong and active. Below are some of the companies you might be familiar with.
