vendorlockin

Vendor lock-in, or vendor lock-in risk, is a condition in which a customer becomes dependent on a vendor for products or services and faces substantial switching costs, friction, or inability to move elsewhere. This dependence can arise from proprietary technologies, non-portable data, ecosystem-specific integrations, or contractual provisions that deter leaving.

Common mechanisms include proprietary file formats and data schemas that hinder export, closed APIs with limited interoperability, integration with other vendor products, customized training and workflows, and long-term contracts with termination penalties. Network effects, economies of scale, and strong customer immersion (e.g., with a single cloud provider, software suite, or device ecosystem) reinforce the lock-in.

Vendor lock-in is frequently discussed in software, cloud computing, hardware, and digital platforms. Examples include cloud service providers with non-portable data and API compatibility requirements, mobile operating systems and app ecosystems that rely on a single storefront, and enterprise software suites that are deeply integrated with internal processes.

Impacts can include reduced competition, higher prices, slower innovation, and increased operational risk if the vendor experiences outages or price changes. Critics argue that lock-in can be leveraged to extract favorable terms or delay transition to better alternatives.

Mitigation strategies include favoring open standards and portable data formats, designing with modular architectures and clear exit paths, choosing products with well-documented APIs and data export options, and pursuing multi-vendor strategies or interoperability commitments in contracts.
