I built a free Azure naming tool that knows every resource type's rules

Every Azure team needs a naming convention, and Microsoft's Cloud Adoption Framework defines a good one. The annoying part is that the rules are scattered and every resource type is different. Storage accounts: 3 to 24 characters, lowercase, no hyphens, globally unique. Key Vault: 24 characters, and soft delete reserves a deleted vault's name for 90 days. Container registries: alphanumeric only.

I got tired of cross-referencing the docs and still hitting name errors at deploy time, so I put together AzureNamer.

What it does:

Generates CAF compliant names for 204 resource types, each with its real length and character rules applied
Exports the whole set as Terraform, Bicep, JSON, Markdown or CSV
The Terraform and Bicep exports have a parameterized mode: variable blocks plus derived name expressions, so one file produces correct names for dev, staging and prod. Names the engine had to shorten stay literal with a comment instead of silently drifting
Parses an existing name back into its components (type, workload, environment, region)
Includes a naming rules reference page for every resource type and a searchable CAF abbreviations cheat sheet

It's free, no login, and fully static, so your inputs never leave the browser.

It started as a side project to scratch my own itch, so feedback is genuinely welcome, especially wrong abbreviations or missing resource types. Hope it saves someone a 2am deploy failure over a name that's one character too long.
