Where each one falls short

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

Astro

  • 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

OBS Studio

  • The Windows build supports only Windows 10 and 11
  • The macOS build requires macOS 13.0 or newer
  • Linux support is distributed as a Flatpak and as a PPA for Ubuntu 24.04 and later rather than official packages for other distributions
  • Game Capture is a Windows only source
