  • Smaller ecosystem compared to Next.js; fewer third-party component libraries and integrations readily available
  • Build time increases with large content volumes (1,000+ pages); incremental builds not yet as optimised as Gatsby or Next.js
  • API routes and serverless functions are less mature than Next.js; complex backend integrations require additional tooling

Java

  • Windows support limited to 64-bit operating systems only
  • Linux installation requires manual path configuration for most installation methods
  • macOS support limited to Intel x64 and Apple Silicon (AArch64) architectures
