Four platforms, one decision: which DXP is right for your organisation?
A practical guide to comparing Optimizely, Sitecore, Contentstack and Sanity.
)
Choosing a new CMS or DXP often seems like a technical decision. But its impact extends far beyond technology alone. The choice you make today will determine how efficiently content teams can work, how much freedom marketers have, how easily integrations can be managed and how scalable your digital landscape remains in the years ahead.
Yet many platform selection processes still start with the wrong questions. Which vendor ranks highest in Gartner? Which platform does a competitor use? Or which solution offers the most features? Those are not the factors that determine whether a platform will be successful within your organisation.
The real challenge lies elsewhere. Does the platform fit the way your teams create, manage and distribute content? Does it support your digital ambitions? And will it still be the right choice three or five years from now?

Choosing a platform is about more than features
Optimizely, Sitecore, Contentstack and Sanity are among the most widely discussed Digital Experience Platforms today. However, the differences between them are greater than many organisations realise. Some platforms take an integrated suite approach, bringing together content, personalisation, data and experimentation in a single ecosystem. Others fully embrace a composable architecture, where flexibility takes centre stage. This makes platform selection a complex process.
In this whitepaper, we compare all four platforms based on real-world experience. Not through marketing promises or feature lists, but through the decisions that make a genuine difference in practice. We explore architecture, AI capabilities, governance, personalisation, integrations, scalability and operational impact. The result is a clear set of insights to help you choose a platform that aligns with your organisation, teams and growth ambitions.
