Vendor lock-in in cloud computing is well-understood: organizations evaluate switching costs and plan exit strategies. In frontend infrastructure, this awareness is largely absent – yet the dependencies are at least as deep.

How Frontend Lock-in Develops

Framework lock-in: Next.js, developed by Vercel, features optimal functionality only on Vercel’s platform. Migration requires a complete application rewrite.

Design tool lock-in: Figma stores all artifacts in a proprietary cloud with no complete export to open formats. Switching to Penpot means manually rebuilding designs.

CDN lock-in: Migration from Cloudflare or AWS CloudFront is technically possible, but platform-specific configurations (Edge Rules, Workers, Cache Policies) increase switching effort.

Package registry lock-in: npm Registry (operated by GitHub/Microsoft) is the default source for JavaScript packages – a dependency on a US platform.

The Cost of Lock-in

Direct costs: Price increases that must be accepted because switching costs are higher. Figma raised prices 25% in 2023.

Opportunity costs: Better or cheaper alternatives can’t be used because migration is uneconomical.

Risk costs: Availability outages, license changes, or geopolitical factors. The CLOUD Act grants US authorities access to data at US companies.

Exit-Capable Architectures

The EU Data Act (from September 2025) mandates open interfaces and maximum 2-month notice periods for cloud services. From January 2027, cloud providers may not charge switching fees.

Key Takeaways

  • Frontend lock-in develops gradually through frameworks, design tools, CDNs, and package registries.
  • Costs are threefold: direct price increases, missed alternatives, geopolitical risks.
  • The EU Data Act mandates exit-capable architectures from September 2025.
  • Design tokens in W3C format and headless architectures are the most effective mitigation strategies.
  • Exit capability is the strongest negotiating position with any vendor.
