Open source tools & projects
Tools I've built to solve real SRE problems — most of these came from something that burned me on-call or slowed down a migration.
SLO Dashboard Generator
Generates production-ready Grafana dashboards from a simple YAML SLO definition. Supports multi-window burn-rate alerts, error budget visualization, and Grafonnet templating for consistent dashboards across hundreds of services.
k8s-runbook-operator
A Kubernetes operator that attaches structured runbooks to PodDisruptionBudgets, Deployments, and Services. Automatically surfaces the relevant runbook URL in PagerDuty alerts and Slack incident channels via annotations.
victoria-metrics-migrator
CLI tool for migrating Prometheus recording rules, alerting rules, and dashboards to Victoria Metrics. Includes a cardinality analyzer to identify high-cardinality metrics before migration.
alloy-config-validator
Validates Grafana Alloy (formerly Agent Flow) pipeline configurations in CI. Checks for syntax errors, validates target labels, and warns about high-cardinality label combinations before they hit production.
incident-cost-estimator
Estimates the real cost of incidents based on MTTD/MTTR, affected revenue streams, and team time. Integrates with incident.io webhooks to auto-calculate cost per incident and trend over time.
terraform-sre-modules
Opinionated Terraform modules for SRE infrastructure: multi-region ALB with health checks, RDS with automated failover, EKS node groups with proper taints, and CloudWatch alarm baselines.
All projects are open source. Contributions, issues, and ideas welcome.
