Composable DXP: What is it, and why does it matter?

Managing digital experiences today isn’t just about having a website or an app—it’s about delivering seamless, personalized interactions across every digital channel your customers use. A Digital Experience Platform (DXP) helps businesses like yours optimize the customer journey, streamline content management, and orchestrate marketing campaigns from one central hub.

Joe Cicman from Forrester raises an important question: “How is it possible for one vendor to create one product that works across multiple industries and grows in scope as a company’s digital remit grows?” The truth is, it’s not. One-size-fits-all platforms simply can’t meet the dynamic needs of modern businesses.

That’s why Composable DXPs are gaining traction. Unlike traditional, monolithic DXPs that force you into a rigid ecosystem, a Composable DXP allows you to build a tailored digital stack using best-in-class solutions. You can choose the right tools—a Headless CMS, Product Information Management (PIM) system, Digital Asset Management (DAM), or a commerce engine—and seamlessly integrate them into a unified, flexible digital experience.

With a Composable DXP, you’re in control. You can design a digital ecosystem that meets your business needs today while staying agile enough to evolve tomorrow.

What is a composable DXP?

A Composable DXP is a digital experience platform built using modular components, enabling businesses to select and integrate the best tools for their needs. Unlike traditional DXPs that come as an all-in-one suite, a composable approach allows organizations to combine independent, best-of-breed solutions such as Headless CMS, Product Information Management (PIM), Digital Asset Management (DAM), Commerce Engines, and Customer Data Platforms (CDPs) via APIs and microservices.

By leveraging MACH (Microservices, API-first, Cloud-native, and Headless) principles, Composable DXPs offer agility, scalability, and customization that legacy systems cannot match.

Key characteristics of a composable DXP

What makes a composable digital experience platform (DXP) truly composable? It comes down to five defining attributes that set it apart from legacy, all-in-one platforms. These features empower businesses to build, evolve, and scale their digital experience stack with precision and flexibility:

• Modular Architecture: At the heart of a composable architecture is modularity. Each component—whether it’s a CMS, PIM, DAM, or commerce engine—functions as a standalone service that integrates effortlessly with others. This means you can build your tech stack using only the capabilities you need, without unnecessary bloat or dependencies.
• API-First Approach: Composable DXPs rely on robust APIs to connect systems, enabling real-time data sharing and seamless communication between tools. Whether you’re syncing customer data from a CDP to your personalization engine or pushing content from a headless CMS to a mobile app, APIs are what make it all work—quickly and securely.
• Cloud-Native Infrastructure: Born in the cloud, composable DXPs are designed for scalability. This infrastructure supports elastic performance, automatic updates, and lower operational overhead. As a result, businesses can expand into new markets or channels without needing to overhaul their underlying systems.
• Headless Capabilities: Traditional systems tie the front-end to the back-end. A headless approach decouples content delivery from content management, allowing you to distribute experiences across multiple touchpoints—websites, mobile apps, IoT devices, kiosks, and beyond. This creates more consistent and agile digital engagement opportunities.
• Business Agility: Finally, composable DXPs are built for change. As consumer preferences shift and new technologies emerge, your business can respond quickly—swapping out or upgrading components without destabilizing the entire platform. This ensures your digital experience stays modern, competitive, and aligned with evolving customer expectations.

The role of APIs and microservices in a composable DXP

APIs and microservices architecture are the backbone of Composable DXPs. Instead of relying on a single monolithic platform, businesses can leverage API-driven integrations to connect various digital tools effortlessly.

For instance, a Product Information Management (PIM) system like inriver can be integrated with a Headless CMS and an eCommerce engine, ensuring seamless product data synchronization and a consistent omnichannel experience.

The core components of a composable DXP

A Composable DXP consists of several key components, each crucial to managing and delivering digital experiences.

1. Headless CMS: A Headless CMS decouples content management from content delivery, allowing businesses to distribute content across multiple digital channels (web, mobile, IoT, kiosks, etc.). Unlike traditional CMSs tightly coupled with front-end frameworks, a headless CMS enables brands to personalize content experiences while maintaining complete control over presentation and delivery.
2. PIM (Product Information Management): PIM software is essential for e-commerce businesses managing large product data catalogs. It ensures accurate, consistent, and enriched product information across multiple sales channels, reducing errors and enhancing customer trust. Platforms like Inriver PIM help businesses centralize and distribute product data efficiently.
3. DAM (Digital Asset Management): A DAM system helps businesses manage images, videos, graphics, and other digital assets in a structured way. Integrating DAM into a Composable DXP ensures brand consistency across all customer touchpoints.
4. Commerce Engine: A commerce engine provides the core e-commerce functionality, such as order management, pricing, and checkout processes. Businesses can integrate the best eCommerce platform with their Composable DXP to create personalized and seamless shopping experiences.
5. Customer Data Platforms (CDP): A CDP consolidates customer data from multiple sources to provide a unified customer view. This allows businesses to deliver highly personalized digital experiences and targeted marketing campaigns.
6. Integration and APIs: APIs connect all the components of a Composable DXP, allowing businesses to choose and integrate the best tools without vendor lock-in.

Why composable DXP matters

In today’s landscape, where customer data drives strategy and preferences evolve at lightning speed, enterprises need a future-proof digital experience that’s flexible, scalable, and resilient. A composable DXP delivers just that.

By adopting a composable architecture, organizations gain the agility to adjust their tech stack as needs change—whether it’s integrating a new analytics tool, swapping out a headless CMS, or adapting to a new commerce channel. You’re not locked into a monolithic setup. Instead, you choose the best components to build a dynamic, modular digital experience platform (DXP) that evolves with you.

Composable DXPs allow you to meet rising customer expectations without replatforming. You can quickly integrate AI-driven personalization engines, sync customer data across touchpoints, and deliver consistent, omnichannel experiences—all without disrupting your core systems.

Perhaps the biggest advantage? Freedom of choice. Instead of being tied to a single vendor and limited functionalities, you can create a customized solution tailored to your goals. When better tools emerge, simply plug them into your DXP—no heavy lifting required.

Composable DXP vs. traditional DXP

Traditional DXPs provide an all-in-one, monolithic solution where a single vendor bundles together content management, eCommerce, and analytics. While this simplifies vendor management, it limits flexibility, scalability, and innovation. Customization is often restricted, and integrating third-party solutions can be complex.

In contrast, Composable DXPs offer a modular approach, allowing businesses to select and integrate the best tools for each function using APIs and microservices. This ensures greater agility, seamless scalability, and the ability to adapt to evolving market trends without being locked into a single provider.

Scalability and personalization are also key differentiators. Traditional DXPs require significant expansion upgrades, leading to higher costs and longer implementation times. Meanwhile, Composable DXPs let businesses scale effortlessly by adding or replacing components without disrupting the system.

Additionally, advanced personalization is easier to achieve with a Composable DXP, as businesses can integrate best-in-class Customer Data Platforms (CDPs) and AI-driven analytics for deeper customer insights. While Traditional DXPs offer ease of management, Composable DXPs provide long-term flexibility, innovation, and cost efficiency, making them the preferred choice for organizations prioritizing agility and scalability in their digital transformation journey.

Personalization: Why It’s the Heart of Composable DXP

With a composable DXP, personalization becomes a strategic advantage—not just a campaign feature. Because you can integrate specialized Customer Data Platforms (CDPs), AI engines, and testing tools, you’re able to serve content that aligns with where each user is in their journey—across channels, in real time.

This modular setup gives you the flexibility to personalize based on behavior, location, intent, purchase history, or even content engagement patterns. Whether you’re running an eCommerce storefront, a B2B portal, or a global brand site, composable architecture means personalization is no longer limited by what your platform can or can’t do. You build the experience that fits your audience—now, and as their needs shift.
