AWS Engineer Toolkit
AWS engineers manage cloud infrastructure at scale — from IAM policies and Lambda functions to VPC configurations and CloudFormation stacks. The work generates a constant stream of JSON payloads, Base64-encoded values, and timestamps that need quick inspection. These free, browser-based tools handle those micro-tasks without leaving the browser or installing additional CLIs.
JSON Formatter & Validator
Pretty-print IAM policy documents, CloudFormation outputs, Step Functions definitions, and API Gateway responses. The formatted view reveals overly permissive wildcards and misconfigured resources that compact JSON hides.
Base64 Encoder / Decoder
Decode Base64-encoded values from CloudWatch Logs Insights, Lambda environment variables, and EC2 user data scripts. Encode configuration data for passing to launch templates and container definitions.
Timestamp Converter
Convert Unix epoch timestamps from CloudTrail events, DynamoDB TTL fields, and CloudWatch metrics to human-readable dates. Critical for incident investigation and audit trail analysis.
JSON to YAML Converter
Convert CloudFormation JSON templates to YAML — the preferred format for readability. Translate API responses into SAM template format or CDK configuration files.
RegExp Tester
Build regex patterns for CloudWatch Logs Insights queries, Lambda log parsing, and S3 event notification filters. Test patterns before deploying them in metric filters or subscription filters.
Code Diff Tool
Compare CloudFormation templates, Terraform state files, or IAM policies before and after changes. The visual diff provides clear evidence of infrastructure drift for change management documentation.
cURL Converter
Test API Gateway endpoints, Lambda function URLs, and custom REST APIs. Convert AWS documentation examples into working cURL commands with the correct headers and authentication.
Crontab Calculator
Validate cron expressions for EventBridge rules, Lambda scheduled invocations, and AWS Batch job definitions. AWS cron syntax has subtle differences — verify before deploying.
MD5 / Hash Generator
Generate SHA-256 checksums for S3 object integrity verification, Lambda deployment package validation, and CloudFormation template hashing.
IP Address Lookup
Look up IP addresses from VPC Flow Logs, ALB access logs, and CloudFront distributions. Identify geographic origin and hosting provider for security analysis and traffic optimization.
URL Encoder / Decoder
Encode S3 object keys with special characters, decode CloudFront signed URLs, and fix percent-encoding issues in API Gateway path parameters.
Password Generator
Generate strong passwords for RDS master users, Secrets Manager entries, and IAM user initial credentials. Ensures compliance with AWS security best practices.
