Where each one falls short

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

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

shadcn/ui

  • No upgrade path: once copied, upstream fixes and improvements are yours to port by hand
  • Requires Tailwind and React, so it is not an option outside that stack
  • Component code lives in your repository, which grows it and puts maintenance on your team
  • Its popularity has made the default look recognisable, which undercuts the customisation argument

Answered from the vendors’ own pages

Buildkite: Can I use Buildkite without paying?

Yes, Buildkite offers a free plan that includes up to 5 users, 10 concurrent jobs, 2000 Linux vCPU minutes monthly, and 250k test executions per month at no cost.

Source
shadcn/ui: Is shadcn/ui free?

Yes, open source and free for commercial use.

Buildkite: What happens if I exceed my included compute minutes on Buildkite?

Source
shadcn/ui: Why is it not an npm package?

So you own the code. Components are copied into your project, which makes customisation trivial — at the cost of receiving no automatic updates.

No, Buildkite's Pro plan is billed monthly at $30 per active user with no long-term contract required. All tiers include a 30-day all-access trial.

Source
shadcn/ui: Do I need Tailwind?

Yes. Components are styled with Tailwind utility classes and built on Radix primitives, so both are required.

Buildkite: What user limits apply to each Buildkite plan?

Free plan supports up to 5 users, Pro plan supports up to 50 users, and Enterprise plan provides unlimited users with a 30-user minimum.
