IAM Policy Visualizer

Paste an AWS IAM or S3 bucket policy to see every statement as a plain-English allow or deny card, with wildcard, public access and privilege escalation risks flagged.

      "Effect": "Deny",
      "Principal": "*",
      "Action": "s3:*",
      "Resource": [
        "arn:aws:s3:::shop-assets",
        "arn:aws:s3:::shop-assets/*"
      ],
      "Condition": {
        "Bool": {
          "aws:SecureTransport": "false"
        }
      }
    },
    {
      "Sid": "AdminEverything",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::123456789012:root"
      },
      "Action": "*",
      "Resource": "*"
    }
  ]
}

An explicit Deny always wins over any Allow. Anything not allowed is denied by default.
