The ability to see memory usage in real time—and quickly identify leaks or abnormal spikes—makes troubleshooting far more efficient. On top of that, tracking every request gives complete visibility into application performance, helping pinpoint slow transactions or bottlenecks with precision.

Another standout feature is its built-in crash protection and monitoring. Knowing the system can automatically detect critical issues and help prevent unexpected downtime provides real confidence in production environments.

Overall, FusionReactor APM combines deep visibility with proactive protection, which makes it an invaluable tool for maintaining application stability and performance. Review collected by and hosted on G2.com.

Some advanced features require careful configuration to get the most value from them. Without proper tuning, it’s possible to either miss important insights or collect more data than necessary, which can impact performance or clarity. Review collected by and hosted on G2.com.

FR brings "light into the darkness" for me. I also like how this monitoring software is constantly being expanded and developed in a progressive manner. The cloud integration offers many advantages. I can't say directly what I like best about it; for me, it is a daily tool to observe, check, and monitor the direct impacts of my work on the servers. For error analysis, it provides me with very tailored tools and usually gets me to the goal immediately. I also really like the AI support. It often provides very useful tips to narrow down errors.

Fundamentally, it is very expensive. We have a lot of instances in the cloud, and we cannot run it on all installations, as that would far exceed our budget. Compared to the range of functions, the price is certainly justified, but as a standard monitoring tool on all instances, it is unfortunately too expensive, at least in our environment.

I have used Fusion Reactor on both my CF11 and CF23 installations, and I find that the insights it offers are both comprehensive and detailed. This has made performance tuning and fault detection significantly quicker and much easier for me. Kudos also to their excellent customer service. Review collected by and hosted on G2.com.

A very minor issue (so minor I'm not really complaining about it - this review just wanted something negative, so I'm trying here, lol) is how tightly it binds to CF -- to turn FR off for any reason, you have to stop your CF installation briefly. Review collected by and hosted on G2.com.

FusionReactor is vital to our org to ensuring we are getting the best of ColdFusion. Our favorite feature is the ability to monitor slow transactions, which immensely helps us in tuning our web pages. The customer support is friendly and quick, and they are eager to assist if you run into any issues. It is also very easy to login and setup and to see what you are looking for.

I cannot say anything bad about FusionReactor itself. It fits our needs and has been a great tool for us to catch issues before they even happen. Review collected by and hosted on G2.com.

We use FR on a daily basis to either assist in troubleshooting or just general performance monitoring.

Installation and integration with Coldfusion servers is straightforward and easy to automate (we use ansible).

Customer support is stellar. Hands on, without too much bureaucracy and back and forth with the support team, with quick turnaround times.

We recently moved to the Cloud + AI platform and it has more features than we know to use. We're still in the process of learning the ropes, but it provides with a more holistic view of our infrastructure compared to our old on-prem deployments. Review collected by and hosted on G2.com.

Nothing comes to mind immediately in terms of dislikes.

I would say that sometimes a setting is in a different place than what you would think.

There are various settings menus per function that may get confusing at times. Review collected by and hosted on G2.com.

I like how easy it is to navigate the application. I only saw the demo but the data insights the application gives into the development process is very helpful. It also has support for legacy languages as well. As someone who has used cfm I can see how helpful this application can be. Review collected by and hosted on G2.com.
