What Robusta is
Robusta is an AI SRE for investigating infrastructure alerts and supporting incident response. It groups duplicate alerts, filters noise, and surfaces new issues; its AI can investigate an alert, identify root cause and blast radius, propose a fix, and escalate to a person when needed. Alerts can arrive through webhooks, HTTP requests, or MCP events, with listed tools including Prometheus AlertManager, Grafana, Datadog, PagerDuty, and Jira. Holmes has native integrations for Kubernetes, OpenShift, AWS, Azure, GCP, Prometheus, Grafana, PostgreSQL, GitHub, and ServiceNow. It can also connect through MCP servers or HTTP APIs and generate a connector for an HTTP API. Deployment options are SaaS, a customer's VPC, or fully self-hosted with the customer's own LLM key. Customers can choose their own models and API keys or disable Robusta-hosted models. Robusta says customer logs, traces, and incidents are used to answer questions, not train models. The agent is read-only by default; write access for automated remediation is optional. Queries, log lines, and conclusions are logged and replayable. Pricing is by quote, and Robusta says its core is open source.
