OpsPilot

OpsPilot OpsPilot is an AI-powered observability and autonomous reliability platform with an AI Site Reliability Engineering (SRE) teammate that helps engineering and operations teams detect, understand, and resolve incidents faster — and increasingly prevent them from happening at all. Your 24/7 stack expert Modern production systems — microservices, distributed architectures, cloud and hybrid environments — generate enormous volumes of telemetry. Your existing tools surface that data. But they still leave engineers responsible for interpreting signals, finding root causes, and deciding what to do next. OpsPilot closes that gap. It continuously analyzes telemetry across your applications, infrastructure, and services — then tells your team what is happening, why it is happening, and what to do about it. From dashboards to autonomous reliability OpsPilot goes beyond alerting and visualization. It correlates signals across metrics, logs, traces, and deployment events to identify abnormal behavior, explain root causes, and guide teams toward faster resolution — dramatically reducing time spent on incident investigation and operational troubleshooting. Over time, it evolves from reactive investigation toward proactive and autonomous operations. Your AI SRE teammate OpsPilot acts as an AI SRE teammate — augmenting your operations team by answering the questions engineers face during incidents: What changed? Where is the failure occurring? Which service is responsible? What should we investigate next? Three core capabilities Observability — collects and correlates telemetry across metrics, logs, traces, JVM data, and application-level diagnostics for a complete picture of system behavior. Operational Intelligence — applies AI-driven analysis to surface what changed, what is causing the issue, which components are involved, and what actions may resolve it. Foundational capabilities include anomaly detection, alert reduction, telemetry correlation, and root cause analysis. Action and Automation — supports guided incident response, runbook generation, automated remediation, and continuous operational learning — moving teams progressively toward autonomous reliability. OpenTelemetry-native. No new agents required. OpsPilot ingests telemetry via OTLP over gRPC or HTTP — no proprietary agent required. It works with your existing OpenTelemetry instrumentation across Kubernetes, microservices, cloud services, and serverless platforms. Prometheus-compatible metrics, Loki log ingestion, and Jaeger/Zipkin trace formats are also supported. For teams needing deep JVM or ColdFusion diagnostics, the optional FusionReactor APM agent provides additional application-level telemetry. Built for DevOps, SRE, and platform engineering teams OpsPilot is designed for organizations running modern production systems that require high reliability and operational efficiency — particularly teams moving toward SRE or platform engineering models who need deeper operational insight without increasing headcount. Deployed as SaaS, hybrid, or agentless via OpenTelemetry.
