The New Relic One observability platform has become programmable, allowing users to connect their observability data to business decisions. To showcase this capability, New Relic has developed a handful of open-source applications that can be deployed on the platform. These applications include Container Explorer, Deployment Analyzer, and Page View Map, which provide tools for visualizing container inventory, deployment analysis, and geographic visualization of browser application data. The applications are available under an open-source license and can be deployed locally using the New Relic CLI or published to a personal account. New Relic also offers resources for building custom applications, including the Developer Edition and SDKs, as well as community support through the Explorers Hub. Contributions to these open-source projects are welcome, and users can preview more apps in future editions of this series.
