FusionReactor

What FusionReactor is

FusionReactor is application performance monitoring software from Intergral GmbH that helps teams understand why applications slow down or fail. Its agent monitors Java and ColdFusion applications, with deployment on-premise or as an addition to Cloud; the maker says data can stay local. The product combines real-time application monitoring with continuous profiling, database monitoring, anomaly detection, full trace capture, call trees, and method-level detail. Profiling covers code, memory, threads, CPU, and garbage collection, with source map support and continuous alerts. The agent can export Java and ColdFusion telemetry to OpenTelemetry-compatible backends, including Datadog, New Relic, Grafana Cloud, Honeycomb, and Splunk. The Developer Edition is intended for development and test environments, helping teams find issues and performance bottlenecks before production deployment. Plans include cloud options with stated allowances for metrics, logs, traces, and OpsPilot Tokens; usage beyond an allowance switches to on-demand for the remainder of the billing period. The Developer License is $22 a month. A 14-day trial is available without credit card details at signup. Intergral GmbH is headquartered in Ebhausen, Germany; the maker states its personal data processing is GDPR compliant and Intergral Information Systems GmbH is SOC 2 Type 2 compliant.

Who it suits

FusionReactor suits teams running Java or ColdFusion applications that need performance details such as traces, call trees, database activity, and profiling. Its Developer Edition is aimed at development and test environments, while on-premise deployment may suit teams that want data to remain local.

Limits

There is no free plan. The trial lasts 14 days; cloud plan allowances vary, and usage beyond them switches to on-demand for the rest of the billing period.

Getting started

1. Visit the FusionReactor website.
2. Choose a plan, including the Developer License for development and test environments.
3. Start the 14-day trial without providing credit card details at signup.
4. Deploy the monitoring agent on-premise or add it to Cloud for a Java or ColdFusion application.

Verdict

Choose FusionReactor if you need detailed monitoring and profiling for Java or ColdFusion applications, with on-premise deployment or OpenTelemetry export. Look elsewhere if you need a free plan or a maker that can sign a BAA for HIPAA compliance.
