Robusta

Robusta is an AI SRE service that investigates infrastructure alerts and incidents. It groups duplicate alerts into a small number of real incidents, investigates each with full context, and remembers the results so later incidents of the same kind are handled faster. The vendor describes it as making existing incident tools autonomous rather than replacing them. Alerts can arrive from Prometheus AlertManager, Grafana, Datadog, New Relic, Dynatrace, AWS CloudWatch, Sentry, PagerDuty, Opsgenie, Rootly and others, or from any webhook, HTTP API or MCP server. Its investigation agent, called Holmes, reads data through native integrations such as Kubernetes, OpenShift, Helm, ArgoCD, AWS, Azure, GCP, Prometheus, Loki, Tempo, PostgreSQL and MySQL, plus any MCP server. Investigation starts the moment an alert fires and aims to identify the root cause, blast radius and a suggested fix, escalating to a human only when needed. Robusta auto generates a skill for each data source it investigates and suggests the right one in later investigations, which the vendor says reduces token use by 60 percent. The cost argument rests on grouping: the vendor says customers pay per unique incident rather than per duplicate alert, and offers a calculator that estimates savings, using a benchmark of $2.50 per investigation for build your own setups. The pricing page shows no plan prices. It asks teams to submit their company size and infrastructure details to receive a quote.
