Core Components of the 2025 Sitecore Technology Stack
The modern Sitecore stack can be broken down into four primary layers: the composable core (Sitecore's SaaS products), the frontend experience layer, the backend development layer, and the underlying cloud infrastructure.
🧠 The Brain: Sitecore's Composable Core (SaaS Products)
This is the heart of the new ecosystem. Instead of one massive platform, Sitecore now offers a suite of specialized, cloud-based services that communicate via APIs.
- Sitecore XM Cloud: This is the flagship SaaS CMS and the direct successor to Sitecore XM. It provides a completely headless content repository, a visual page builder (Pages), and an integrated DevOps workflow. It's the foundation upon which you build your digital experiences.
- Sitecore Search: A powerful, AI-driven search solution that provides relevant and personalized search results for your website. It replaces the more basic search functionalities of the past.
- Sitecore Content Hub: A comprehensive solution for digital asset management (DAM), product information management (PIM), and marketing resource management (MRM). It acts as a centralized content hub for the entire enterprise.
- Sitecore Connect: An integration platform (iPaaS) that allows you to easily connect Sitecore products to each other and to third-party systems using a low-code/no-code interface, powered by Workato.
- Sitecore Personalize & CDP: These tools provide the advanced personalization and customer data platform capabilities previously found in Sitecore XP, but now as standalone, composable services that can be used with any platform.

With a headless CMS, the frontend is completely decoupled from the backend. This gives developers the freedom to use modern JavaScript frameworks to build fast, interactive user experiences. This approach is central to modern Cross Platform App Development Explore Frameworks Technology And Business.
- Next.js: While you can use any frontend framework, Next.js (built on React) is Sitecore's officially supported library for XM Cloud. It offers features like server-side rendering (SSR) and static site generation (SSG), which are critical for performance and SEO.
- Vercel: The preferred hosting platform for Next.js applications connected to XM Cloud. Vercel provides a seamless deployment experience, global CDN, and serverless functions that work in perfect harmony with Sitecore's new architecture.
- GraphQL: This is the query language used to fetch content from Sitecore's headless services. It's more efficient than traditional REST APIs because it allows frontend developers to request exactly the data they need and nothing more.
- Other Frameworks: While Next.js is recommended, the headless nature of the platform means you can still use other popular frameworks like Angular, Vue.js, or Svelte.
⚙️ The Backend: The Power of .NET Core
The backend logic of Sitecore has been completely modernized, aligning it with the broader What Is The Microsoft Technology Stack All About. The move from the Windows-only .NET Framework to the cross-platform .NET Core (now just called .NET) is a game-changer.

Frequently Asked Questions
Is Sitecore XP still supported in 2025?
Yes, Sitecore continues to offer mainstream support for Sitecore XP 10.x versions. However, all new feature development and innovation are focused on the new composable, cloud-native products like XM Cloud. Organizations on XP should be planning their migration strategy to the composable DXP to take advantage of the new architecture and avoid future support limitations.
Do I have to use Next.js and Vercel with Sitecore XM Cloud?
While Next.js is the officially supported JavaScript framework and Vercel is the recommended hosting platform, you are not strictly locked in. Sitecore's headless APIs (primarily GraphQL) can be consumed by any frontend application, whether it's built with Angular, Vue, Svelte, or another technology. However, using the recommended stack provides the most seamless integration and access to features like the visual page editor.
How does the new Sitecore stack affect licensing and cost?
The cost model has shifted from perpetual licenses (common with Sitecore XP) to a subscription-based model (SaaS). This changes the cost from a large, upfront capital expenditure (CapEx) to a more predictable operating expenditure (OpEx). The composable nature also allows you to purchase only the services you need (e.g., just the CMS, or the CMS plus search), potentially lowering the total cost of ownership by eliminating unused features and reducing infrastructure management overhead.
What is the biggest challenge when migrating from Sitecore XP to XM Cloud?
The biggest challenge is typically twofold: technical and mindset. Technically, it involves refactoring your solution to fit a headless architecture. Frontend code (renderings) must be rebuilt in a modern JavaScript framework, and backend code needs to be migrated from .NET Framework to .NET Core and potentially containerized. The mindset shift involves moving from a tightly-coupled development process to a decoupled, API-first approach, which requires new workflows and collaboration between frontend and backend teams.
