Frequently Asked Questions

Sitefinity offers a full spectrum of deployment options to suit different business needs, including on-premises (self-hosted or via a partner), a cloud-based Azure-hosted Platform as a Service (PaaS), and a fully managed Software as a Service (SaaS) model. This flexibility lets organizations choose how to host their composable DXP: they can maintain full control with an on-premise deployment or enjoy the convenience of cloud hosting via Sitefinity Cloud (PaaS) on Microsoft Azure. For companies without extensive IT resources, Sitefinity’s SaaS option provides a turnkey always-on and always-current cloud solution— the Sitefinity platform is managed and updated by Progress, so the business can focus on delivering digital experiences while the vendor handles infrastructure, security, and maintenance.
Sitefinity comes with robust integration and extensibility tools that make it easy to connect with other systems. Its Integration Hub (built on a leading iPaaS platform, Workato) enables low-code connectivity to 1,000+ third-party applications and data sources, allowing organizations to automate workflows and sync data with a recipe-based low-code approach and without the need for custom development. The platform also supports webhooks (service hooks) that let you trigger external services when events occur in the CMS—for example, sending an HTTP POST to another application whenever content is published. This facilitates a straightforward real-time integration with minimal coding. Additionally, Sitefinity exposes open, well-documented APIs (including a full RESTful content API and GraphQL support) so developers can easily extend the CMS solution or integrate it with virtually any external system, ensuring that Sitefinity fits into a wider composable tech stack.
Sitefinity is built as a hybrid-headless CMS, supporting modern front-end frameworks while still empowering content creators. It provides out-of-the-box renderer applications for both Next.js (React) and ASP.NET Core, meaning developers can decouple the presentation layer and build front-ends using these technologies with Sitefinity delivering content via APIs. Notably, the ASP.NET Core and Next.js renderers come pre-integrated and hosted in Sitefinity’s SaaS environment by default. All supported front-end frameworks maintain full feature parity—marketers get the same drag-and-drop page building, personalization, and editing experience in Sitefinity’s interface regardless of whether the site is running on .NET Core or Next.js. Under the hood, Sitefinity follows an API-first approach with robust REST and OData/GraphQL endpoints, so any front-end (Next.js, Angular, React, etc.) can consume content headlessly and deliver consistent omnichannel experiences.

Progress Sitefinity incorporates a range of embedded AI features—from content generation to personalization—to streamline digital content creation and optimization. For example, it offers AI-assisted content authoring through an integration with Azure OpenAI services, enabling editors to generate, summarize, or improve text right within the rich text editor using pre-built and customizable AI prompts. These AI capabilities are built-in yet extensible through guided AI prompts. The platform also provides intelligent image search and AI-powered translation tools to boost productivity.

Furthermore, Sitefinity’s CDP (Customer Data Platform) and personalization module (Sitefinity Insight) leverages machine learning for audience segmentation and content recommendations—it can automatically discover visitor segments based on behavior and suggest or personalize content for each group—helping marketers deliver relevant experiences at scale.

Sitefinity also allows integration of custom AI models or configurations, so organizations can tailor the AI to their specific content strategy and governance requirements.

Sitefinity is designed to handle complex multi-site and multi-language scenarios with ease, acting as a centralized content hub for global digital experiences. A single Sitefinity instance lets you manage multiple websites (and microsites or portals) and serve diverse regions from one place— you can maintain content in multiple languages and tailor it to different locales, all while ensuring consistent branding and governance across sites.

Thanks to Sitefinity’s headless CMS capabilities, you can create content once and reuse it across multiple channels: the platform allows you to distribute the same content to your main website, mobile apps, customer portals, digital kiosks, or any other channel via flexible content APIs. This content-as-a-service approach means updates are instantaneous and consistent—a marketing team can publish a piece of content or update a product description in Sitefinity, and that change is delivered in real time to all connected sites and channels, providing a unified omnichannel experience for audiences worldwide.
