The short version

  • Only Turbopack has a free tier, so it costs nothing to try first.
  • Each has a real cost: Turbopack effectively coupled to Next.js; using it standalone is not the supported path; WarpBuild per-minute pricing requires tracking usage to estimate monthly costs
  • They diverge on capability: Turbopack covers Incremental computation, WarpBuild covers Optimized runner infrastructure.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

Turbopack

  • Effectively coupled to Next.js; using it standalone is not the supported path
  • Younger than the alternatives, and ecosystem plugin support is narrower than webpack’s
  • Benchmark claims have been contested publicly, so measure on your own project rather than trusting headline numbers
  • Being Vercel-driven ties its roadmap to one company’s framework priorities

WarpBuild

  • Per-minute pricing requires tracking usage to estimate monthly costs
  • Large configuration runners (32 vCPU) expensive at $0.064/min
  • macOS M4 Pro 12-core at $0.16/min is highest-cost option
  • BYOC option requires cloud setup by customer

Answered from the vendors’ own pages

Turbopack: Is Turbopack free?

Yes, open source from Vercel.

WarpBuild: How much cheaper is WarpBuild compared to GitHub Actions?

WarpBuild offers approximately 50% cost savings compared to GitHub-hosted runners. For example, Linux x86-64 2vCPU/8GB costs $0.004/min with WarpBuild vs $0.008/min with GitHub Actions.

Turbopack: Can I use Turbopack without Next.js?

Not really. It is developed as the Next.js bundler, and standalone use is not the supported path.

WarpBuild: What is BYOC and how does it differ from managed runners?

BYOC (Bring Your Own Cloud) allows customers to run WarpBuild on their own cloud infrastructure at $0.002/min. Managed runners use WarpBuild's cloud infrastructure. BYOC provides lower costs but requires customer setup.

Turbopack: Is Turbopack faster than Vite?

It depends on the project, and published comparisons have been disputed by both sides. Measure on your own codebase rather than relying on headline figures.

WarpBuild: Does WarpBuild support ARM64 runners?

Yes, WarpBuild offers ARM64 runners at lower costs than x86-64. Linux ARM64 starts at $0.003/min for 2vCPU/8GB configuration.
