Robusta

CNCF Sandbox Kubernetes alert enrichment and automation platform

open sourceupdated Aug 16, 2026

Robusta is a CNCF Sandbox project that enriches Kubernetes alerts with diagnostic context and automates remediation workflows. It intercepts Prometheus alerts, attaches relevant logs, pod status, resource metrics, and troubleshooting suggestions before delivering them to Slack, Teams, or PagerDuty. Supports custom playbooks for automated incident response and AI-powered root cause analysis.

Robusta transforms the Kubernetes alerting experience by intercepting raw Prometheus alerts and enriching them with the diagnostic context that engineers need to understand and resolve issues quickly. When a pod crash alert fires, Robusta automatically attaches the pod's recent logs, restart history, resource consumption graphs, and related events, transforming a sparse alert into a comprehensive incident report that arrives in Slack, Microsoft Teams, or PagerDuty.

The platform's automation engine executes playbooks in response to specific alert conditions, enabling automated remediation for common operational scenarios. Teams can define playbooks that automatically collect thread dumps from high-CPU Java pods, capture heap snapshots from OOMKilled containers, scale deployments in response to queue depth alerts, or trigger CI/CD rollbacks when error rate thresholds are breached. Custom playbooks are written in Python with access to the Kubernetes API and cluster state.

As a CNCF Sandbox project with over 2,500 GitHub stars, Robusta integrates with the existing Kubernetes observability ecosystem rather than replacing it. It works alongside Prometheus, Grafana, and AlertManager, adding an intelligence layer that reduces mean time to resolution by providing actionable context with every alert. The AI-powered root cause analysis feature correlates multiple signals across the cluster to identify the underlying cause of cascading failures that generate dozens of related alerts.
