Where each one falls short

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

Astro

  • Limited to static site generation and server-side rendering; real-time applications requiring constant client-server communication are unsuitable
  • 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

Buildkite

  • Free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention
  • Pro plan is $30 per active user per month, capped at 50 users, with only 10 of the up to 250 concurrent agents included before extra usage
  • Enterprise plan enforces a 30 user minimum even though pricing itself is custom
  • Hosted compute beyond included minutes is metered at $0.004 per vCPU minute on Linux and $0.02 per vCPU minute on Mac
