# Your AWS account outgrew human attention years ago.

Two hundred services, four consoles deep. Polylane syncs 74 resource types into one graph, reads CloudWatch for you, and fixes what breaks.

## Supported resources

- Lambda Function
- ECS Cluster
- DynamoDB Table
- S3 Bucket
- RDS Instance
- SQS Queue
- EventBridge Rule
- EKS Cluster

## Attention at AWS scale.

### From VPCs to Lambdas

Lambda, ECS, RDS, DynamoDB, SQS, SNS, EventBridge, Step Functions, VPCs and everything wired into them, EKS clusters included. 74 resource types land in one graph with their edges, config, and history.

### Read-only, by construction

Connecting is one CloudFormation stack that creates an IAM role with the AWS-managed ReadOnlyAccess policy. No write, delete, or modify permissions, cross-account assumption only, and the template is open for review before you create it.

### Alarms that investigate themselves

Point your CloudWatch Alarms at Polylane. When one fires, an agent picks it up and starts investigating immediately, so the alarm arrives with an explanation attached.

### Agents read CloudWatch so you don't

Agents comb metrics, logs, and X-Ray traces on a cadence and judge what they see against how each resource normally behaves. No thresholds to tune.

### Who changed what

Each sync records what appeared, changed, or disappeared across the account. When something breaks minutes after an infrastructure change, the investigation starts from that change.

### Investigations that end in a PR

When the root cause is a line of code, the investigation ends in a fix on the repo behind the service, evidence trail attached.

## Questions

**How does Polylane connect to my AWS account?**

Through a CloudFormation stack. You enter your account ID and region, review the pre-loaded template, and create the stack. It provisions an IAM role that Polylane assumes cross-account, and your resources start syncing within minutes.

**Is it really read-only?**

Yes. The IAM role carries the AWS-managed ReadOnlyAccess policy and nothing else: no write, delete, or modify permissions, and it can only be assumed cross-account from Polylane's AWS account. The CloudFormation template is open, so you can review exactly what's granted before creating the stack. Changes to your code only ever land as pull requests.

**What AWS resources does Polylane sync?**

74 resource types: Lambda, EC2, VPC networking, S3, DynamoDB, RDS and Aurora, ECS, EKS (clusters, node groups, Fargate profiles, addons), SQS, SNS, EventBridge, Step Functions, Kinesis, ElastiCache, CloudFront, API Gateway, Cognito, Glue, Redshift, load balancers, and more. The full list is on this page.

**What happens when a CloudWatch alarm fires?**

If you opt in when connecting, Polylane subscribes to the CloudWatch Alarms in the account. When one fires, an agent picks it up and investigates it automatically, correlating it with recent changes and the surrounding resources in the graph.

**Does it work with my observability provider?**

Yes. Datadog, Sentry, Honeycomb, and Axiom join the graph as first-class sources, and their alerts get triaged by an agent the moment they fire.

**What does it cost?**

Pricing is public and self-serve: a free plan, paid plans from $80 a month, and prepaid autofix bundles that never expire. Every plan and limit is published at polylane.com/pricing.
