How It Works

Kyrna tracks AWS costs in real-time while you write Terraform code. Status: Working for AWS only

​
What You See

Per-Resource Cost

Each AWS resource shows its monthly cost

Total Cost

Sum of all resources in your project

​
Example

resource "aws_instance" "web" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t3.micro"          # 💰 $8.35/month
}

resource "aws_db_instance" "main" {
  instance_class   = "db.t3.medium"   # 💰 $61.32/month
  engine          = "postgres"
  allocated_storage = 100              # 💰 $11.50/month
}

# Total: $81.17/month
