Why your e-commerce platform is no longer really yours

In the shadow of the great ads on AI, omnichannel or live shopping, a structural phenomenon silently transforms digital trade: the rise of the app stores. Long perceived as simple repertoires of extensions, these ecosystems have become the beating heart of e-commerce platforms. But this growing dependence raises critical issues: fragmentation, technological overload, loss of control … and appearance of new power relationships.

Massive outsourcing of critical functions

Historically, the e-commerce platforms included in native most of the business functions: catalog, purchase tunnel, CRM, emailing, inventory management, etc. Today, many of these functions are outsourced via apps: marketing automation, loyalty, customization, dynamic merchandising, analytics, generative AI … On certain platforms, more than 80 % of users install at least five third -party apps in the first six months.

The model seems winning: the e-merchant quickly accesses a specialized solution, often low-code, without heavy investment. The publisher of the platform, he enriches his ecosystem at a lower cost. But behind this apparent efficiency, a new dependence sets up.

The illusion of simplicity

With App Stores sometimes exceeding 8000 modules (Shopify), the offer seems plethoric. In reality, few apps concentrate most of the facilities. The market is dominated by some very well funded vertical SaaS actors, which impose their interfacing standards, their update pace and their prices.

In addition, the merchants quickly discover the side effects:

    • stack of redundant solutions,
    • increase in overall cost (cumulative subscriptions),
    • compatibility conflicts,
    • back office overload,
    • Degradation of site performance.

The App Store becomes a labyrinth: apparent freedom masking increasing complexity.

A problematic strategic delegation

In an App Store-Centric model, the e-merchant entrusts strategic functions to third-party publishers: customer data management, scoring, personalized recommendations, segmentation … These apps capture part of the customer relationship, often without the company having complete visibility.

This delegation weakens the ability to build a long -term vision of the product. It also reduces sovereignty over data, limits interoperability, and laying legal risks (GDPR, exportability, data security).

More broadly, it translates a form of technological disengagement: the platform becomes a base, the app stores a patchwork, the final product a sum of dependencies.

The emergence of modular alternatives

Faced with this proliferation, several counter-models appear:

    • The Headless and Composable solutions (Trade Layer, Medusa, Saleor) incorporate few apps but are based on open APIs.
    • Platforms like Swell Or Shogun Fronend offer more closed but more coherent environments.
    • E-merchants again internalize certain critical functions to regain control, even if it means extending the implementation deadlines.

The promise of the App Store – “Plug & Play” – is questioned: the question is no longer only Can we install this app?but Should we delegate this function?

Towards a burst of the platform model

The App Store is no longer a simple functional space. It becomes a market place, a strategic lever, a differentiation factor … but also a risk of fragmentation.

This shift is heavy with consequences:

    • It makes platforms dependent on their own third party ecosystem.
    • It dilutes their value proposal in the face of vertical actors (Klaviyo, Yotpo, Gorgias, etc.) which can decide to become platforms themselves.
    • It accelerates the fragmentation of the e-commerce stack, to the detriment of product consistency.

In this context, the role of the CTO or the e-commerce director evolves: it is no longer a question of choosing a platform, but of orchestrating a Dynamic service ecosystem whose interconnections, costs and governance must be controlled.

Conclusion

App Stores have become a quick innovation engine … but also a silent complexity trap. The challenge for merchants is no longer to choose “the best app”, but rethink their global architectureto arbitrate between short-term simplicity and long-term sovereignty, and to accept that in modern digital trade, the real platform may no longer be the one we believe.
