The short version

  • Each has a real cost: esbuild deliberately does not type-check TypeScript, only strips types, so tsc still runs separately; Readyset pricing requires contacting sales team, making cost planning difficult
  • They diverge on capability: esbuild covers Very fast builds, Readyset covers Automatic Query Optimization.
  • 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.

esbuild

  • Deliberately does not type-check TypeScript, only strips types, so tsc still runs separately
  • Plugin API is far narrower than webpack or Rollup, and complex builds hit its limits
  • Code splitting support has historically lagged the more established bundlers
  • Frequently used indirectly through Vite, so direct use is a narrower need than the download numbers suggest

Readyset

  • Pricing requires contacting sales team, making cost planning difficult
  • Specific pricing tiers not disclosed publicly
  • Requires cache size estimation for cost calculation
  • Limited to read query caching, does not address write performance

esbuild: Does esbuild type-check TypeScript?

No. It strips types for speed and does not check them. Run tsc separately if you need type checking.

Readyset: Is there a free trial?

Yes, Readyset offers a free 7-day trial that lets you test different cache sizes before committing to a paid plan.

Source
esbuild: Do I need esbuild if I use Vite?

You already have it. Vite uses esbuild internally for dependency pre-bundling and transforms.

Readyset: How does Readyset pricing work?

Readyset is available as a monthly or annual subscription charged based on the size of cache you need. Contact [email protected] for specific pricing.
