Developer Utilities tools

Parse and validate AWS ARNs, S3 URLs, Azure resource IDs, Kubernetes RFC 1123 names, and Docker image references — entirely in your browser, structure-only, never a live cloud lookup.

AWS ARN Parser

Parse any AWS ARN into its labeled parts — partition, service, region, account ID, and resource — instantly in your browser. Structure check only, no AWS API calls.

AWS S3 URL Parser

Parse an S3 path-style or virtual-hosted-style URL (or an s3:// URI) into its bucket, key, and region — instantly, in your browser. Flags dotted bucket names.

Azure Resource ID Parser

Parse an Azure resource ID into its subscription, resource group, provider namespace, type, and name — including nested child resources — instantly, in your browser.

Docker Image Reference Parser

Parse a Docker image reference into registry, namespace, repository, tag, and digest — including the implicit docker.io/library and :latest defaults, stated explicitly.

Kubernetes Resource Name Validator (RFC 1123)

Check any Kubernetes object name against the exact RFC 1123 label rules — length, allowed characters, start/end constraints — with every failing rule explained.
