On-Premise or Hybrid Cloud – You Decide !

FusionReactor is a Hybrid monitor, it always comes as On-Premise, but we also offer a Cloud interface. If you have an FR Cloud account, then metric and alerts will be sent to the cloud as well as locally.
FusionReactor Cloud does NOT replace FusionReactor On-Premise – it extends the feature set.

FR Cloud offers some cool additional features and capability, such as extended data retention, tracing, configurable metric graphs and powerful alerting.

The software (Agent) is THE SAME – so you still need to download the installer/software below. If you want to try the Hybrid solution, just click on Start Free Cloud Trial
