Trusted by Industry Leaders
Join hundreds of companies using GoReplay in production
"Today we keep 10 days of traffic in case of problem. We are one of the top 10 French website which means a lot of traffic! Gor saved our life more than once! It was the only way to find very specific issues."
"Gor is really a nice tool and we use it to capture traffic. The traffic is then redirected to 2 versions so that we can compare their performance behavior under real-time production load mix conditions."
"Videology has been using Gor for at least a few months now. Traffic from our production load balancers stream a small slice of traffic to Gor which then streams it to multiple QA environments. We soak test our new and old versions of our web service and the compare their metrics to discover bugs. Great stuff!"
