Cloud infrastructure that heals itself — no humans on call.

Yarrow is an always-on agentic cloud operator. Platform teams declare the intent they want kept true over Terraform, Pulumi, or CloudFormation. A swarm of specialized agents reconciles live state against that intent — and fixes the drift before a human ever gets paged.

The story

No pager rings. No overnight escalations.

Most clouds drift. An IAM key quietly goes stale, a deploy starts misbehaving, a bucket drifts to public-read. Normally, that means a 3 a.m. page. With Yarrow, it means an agent ran a sprinkle and went back to watching — you find out in the morning log, if you care to look.

The agents don't improvise. They replay sprinkles — small, declarative remediations you authored once. Every action is logged, approvable, and reversible.

    Rotate a stale IAM key

    Declare: keys older than 30 days belong to yesterday. The fleet rotates them before they become a finding.

    Gate a misbehaving deploy

    Declare: a canary that misses its SLO for two windows rolls back. The redeployer enforces it without a human looking.

  • sprinkle · rescind-public-read
    repeatable

    Rescind a public-read bucket

    Declare: no object store is world-readable at rest. The patcher flips the ACL the moment the bucket drifts open.

A sprinkle is one declarative fix — rotate a stale key, gate a misbehaving deploy, rescind a public-read bucket — and the agents replay whichever sprinkle the drift calls for.

Supported providers

Layers over the clouds you're already running.

One agent fleet, four surfaces. Sprinkles are authored once and replayed across every account and cluster you're tasked with — same intent, same evidence, same audit trail.

AWS

EC2, ECS, IAM, S3, KMS — full-account reconcile.

Azure

AKS, Entra ID, Storage, Key Vault — policy-as-intent.

GCP

GKE, IAM, Cloud Storage, Secret Manager — declarative.

Kubernetes

Any conformant cluster — admission, rollout, rollback.

Put one workload under Yarrow this week.

We start every team in a sandbox — your stack, your compliance scope, your choice of regional boundary — and only ask for the IAM scopes you want the swarm to use.
