# Contentful: General info & key terms

{% hint style="info" %}
**FE\&R only Integrations.**\
AB Tasty supports client-side Contentful sites through its tag and visual editor, enabling experimentation. The server-side Contentful app extends this capability by allowing teams to run structured content experiments directly from AB Tasty, reducing developer dependency.

### What is Contentful?

Contentful is a **headless CMS** that separates content from its presentation. Teams create structured content once and reuse it across websites, apps, and digital channels.

### Why it matters for AB Tasty

AB Tasty is **fully compatible with client-side Contentful websites** through the AB Tasty tag and visual editor. This allows marketers to easily create and run client-side experiments.

The **server-side AB Tasty app for Contentful** goes beyond that:

The native integration of Contentful and AB Tasty simplifies structured content experimentation by reducing the dependency on developers. Once configured, it allows teams to create and run experimentation campaigns directly in AB Tasty, selecting the content to display for each variation from Contentful.

This application is designed to facilitate test management and content personalisation. It offers the ability to choose a project, a campaign, and its variations, then associate each variation with a content entry. This process is code-free, ensuring a fluid and accessible workflow even for non-technical users.

{% hint style="info" %}
Please note that this integration is only applicable to feature experiments and requires the activation of the Feature Experimentation solution on your AbTasty account.
