## What it is
Piranha CMS is a lightweight, decoupled, open-source content management system for .NET 8 built on ASP.NET Core and Entity Framework Core. It can be used as an integrated CMS with Razor Pages/MVC or as a headless content API, with a Vue.js-based admin panel for editors.

## Use cases
- build a website with a CMS on ASP.NET Core
- add a headless CMS API to serve content to apps
- set up a blog or content site in .NET
- give content editors a friendly admin panel with block editing
- manage a media library with image scaling and cropping
- create a small to medium .NET web application with content management

## When to choose
- you're building on .NET/ASP.NET Core and want a lightweight, extensible CMS
- you need both integrated rendering and headless API delivery from one platform
- editor experience and a clean admin UI are priorities
- you want a MIT-licensed, package-based CMS with project templates

## When to avoid
- you need an enterprise CMS with heavy out-of-the-box marketing features
- your stack is not .NET
- you require a large plugin/marketplace ecosystem
- you need a fully no-code hosted solution
