What is AWS DevOps Agent?
AWS DevOps Agent is AWS's agent for incident response and SRE work, generally available since March 2026.
- Where it works: AWS, plus Azure and on-prem, reading CloudWatch, Datadog, Dynatrace, Grafana, New Relic and Splunk.
- How you get it: Self-serve in the AWS console, 2-month free trial.
- Pricing: $0.0083 per agent-second, about $30 an agent-hour.

- Where you use it: AWS console, Slack, ServiceNow, PagerDuty, MCP.
What is RubixKube?
RubixKube runs read-only observers in your Kubernetes clusters, AWS, Google Cloud and Azure accounts and Linux machines, and takes alerts from Datadog, PagerDuty, Grafana, Sentry and other tools by webhook. It groups related alerts into one incident, and its agent, Rubix, writes a root cause analysis for each one, citing the tool output behind every step and checking quotes in code against what the tools returned.
Every RCA proposes a Fix and Follow-ups. Rubix opens the change as a pull request or through any tool you connect, and you choose how much it may do: Observe only reads, Assist asks before every change, Auto asks before anything destructive. It remembers past incidents and fixes, and works in the console, Slack, the CLI and your own AI tools over MCP.
- How you get it: sign up and start today, no demo and no approval.
- Pricing: Individual is free (1 environment, 10 investigations a month), Business is $999 a month, Enterprise is custom. See pricing.
