Composable DXP vs monolithic
A composable DXP is a digital experience platform built by assembling separately chosen components through APIs, such as a content management system, a search engine or a personalization tool. A monolithic DXP, or integrated suite, provides those capabilities in one product with a shared data model, administration and release schedule.
Definition and how it works
Gartner names four approaches to DXP architecture, among them "composed, fully autonomous suites", then composable architecture, API-first connectivity and hybrid models (Gartner Peer Insights, digital experience platforms market). Matching them to the terms of this entry is Jahia’s reading, not Gartner’s: the integrated suite corresponds to the autonomous suites, and the open platform in the table to the hybrid models. The MACH Alliance, whose MACH Principles describe enterprise technology as open, composable and connected, defines composable this way: "capabilities you can assemble, replace, and evolve independently" (MACH Alliance, MACH Principles page, read 23 October 2026, undated).
The composable approach seeks the best tool for each need, and the freedom to replace one component without rebuilding everything. In return, the assembly becomes a product in its own right. Someone has to design the integrations, manage user identity across components and coordinate vendors that do not share a calendar. The integrated suite reverses the trade-off, at the price of depending on one vendor’s choices and pace.

The differences in detail
Composable describes how the capabilities of a digital experience platform are assembled across products. Headless describes the separation between content and its presentation. A headless CMS can be one component of a composable architecture without making the whole stack composable.
| Approach | What characterizes it |
|---|---|
| Composable DXP | Components chosen separately and connected through APIs. The assembly sits with the organization or its integrator. |
| Integrated suite | A product family sharing data, permissions and administration. |
| Open platform | An integrated core for central capabilities, open through APIs to specialized tools already in place. |
Frequently asked questions
Should we move to composable if our current suite works?
Not on principle. The move makes sense when one specific capability blocks you, for example weak search or a component the vendor no longer develops. You can then replace that component with a specialized tool connected through APIs without dismantling the rest. An architecture can therefore stay mixed.
Is composable cheaper than a suite?
Licenses can be more targeted, but cost moves to integration, operations and coordination between vendors. To compare on equal terms, add up over several years the licenses, the initial integration work, connector maintenance and the time spent testing every upgrade across components.
