Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Read the Docs

  • Build configuration is finicky, and build failures on dependency changes are a common frustration
  • Default themes are recognisable and dated, so sites look alike unless customised
  • Private documentation requires a paid business plan
  • Build times on large projects are slow enough to interrupt a review cycle

Vercel

  • Usage-based pricing can spike unexpectedly during traffic surges or DDoS attacks
  • No spending limit controls or automatic shutoff mechanisms
  • Bandwidth costs ($0.15/GB) quickly accumulate for high-traffic applications
