Walled Garden

A walled garden is a closed platform ecosystem where the operator controls what content, applications, and interactions are available to users—restricting interoperability with external systems and capturing value through gatekeeping.

Walled gardens are the dominant business model in consumer technology. Apple's App Store, Google Play, PlayStation Network, Xbox Live, and Meta's Quest platform all operate as walled gardens with varying degrees of closure. The economic logic is straightforward: by controlling access, the platform can charge commissions (typically 30% on app stores), enforce quality standards, and ensure a consistent user experience. Apple generates over $85 billion annually in services revenue, much of it from App Store commissions.

The tension between walled gardens and open platforms is one of the defining dynamics in technology. Walled gardens optimize for user experience and revenue extraction; open platforms optimize for innovation velocity and ecosystem scale. The Epic Games v. Apple lawsuit, the EU's Digital Markets Act, and similar regulatory actions around the world are attempting to force interoperability and reduce platform gatekeeping power. The DMA requires major platforms to allow third-party app stores and sideloading, directly challenging the walled garden model.

The agentic web thesis argues that AI agents naturally favor open systems. When agents need to discover services, compose tools, and transact across providers, walled gardens create friction that reduces agent effectiveness. The Model Context Protocol and similar open standards route around platform gatekeepers. Open-source AI models prevent any single provider from controlling access to intelligence. The structural advantage of openness—permissionless access, composability, URL-addressability—may ultimately prove more powerful than the control advantages of walled gardens.
