The short version

  • Only Rollup has a free tier, so it costs nothing to try first.
  • Each has a real cost: Rollup slower than the Go and Rust bundlers that followed it, since it is written in JavaScript; WarpBuild per-minute pricing requires tracking usage to estimate monthly costs
  • They diverge on capability: Rollup covers Tree shaking, 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.

Rollup

  • Slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
  • Application concerns like dev servers and hot reloading are not its job, so app builds need Vite on top
  • Configuration for non-trivial applications gets verbose compared with tools that assume more

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

Rollup: Is Rollup free?

Yes, open source under the MIT licence.

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.

Rollup: Rollup or webpack?

Rollup is the usual choice for libraries thanks to cleaner output and better tree shaking. webpack remains stronger for complex applications with heavy asset handling.

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.

Rollup: Do I need Rollup if I use Vite?

Not directly. Vite uses Rollup for production builds, so you already benefit from it.

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.
