esbuild
Web Development
Extremely fast JavaScript bundler written in Go
- From
- Free
- Rated
- -
The short version
- Each has a real cost: esbuild deliberately does not type-check TypeScript, only strips types, so tsc still runs separately; Rollup slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
- They diverge on capability: esbuild covers Very fast builds, Rollup covers Tree shaking.
Where they differ
Only the attributes on which esbuild and Rollup actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), platforms (Linux, macOS, Windows), user rating (Not yet rated), category (Web Development).

What people use each for
The jobs each tool is most often brought in to do.
esbuild
- Build pipelines where bundle time is the bottlenecknot Rollup
- Libraries and tools needing a fast, embeddable bundlernot Rollup
- Replacing slower bundlers where the plugin ecosystem is not needednot Rollup
Rollup
- Publishing a JavaScript library in several module formatsnot esbuild
- Builds where output size and cleanliness matter more than build speednot esbuild
- Producing ES module output for consumers who will bundle it themselvesnot esbuild
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
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

Questions people ask
- Is esbuild or Rollup better?
- Neither clearly leads. esbuild starts at Free and Rollup at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, esbuild or Rollup?
- esbuild starts at Free and Rollup at Free.
- Does esbuild or Rollup run on more platforms?
- Both run on Linux, macOS, Windows, so platform support will not decide this one for you.
- Can I use esbuild for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is esbuild best used for?
- esbuild is most often used for build pipelines where bundle time is the bottleneck, libraries and tools needing a fast, embeddable bundler, replacing slower bundlers where the plugin ecosystem is not needed. Of those, build pipelines where bundle time is the bottleneck and libraries and tools needing a fast, embeddable bundler are not what Rollup is typically brought in for.
- What can esbuild do that Rollup cannot?
- esbuild covers Very fast builds, TypeScript support, Tree shaking and minification, Simple API. Rollup covers Tree shaking, Clean output, Multiple output formats, Plugin API.
Answered from the vendors’ own pages
esbuild: Is esbuild free?
Yes, open source under the MIT licence.
Rollup: Is Rollup free?
Yes, open source under the MIT licence.
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.
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.
esbuild: Do I need esbuild if I use Vite?
You already have it. Vite uses esbuild internally for dependency pre-bundling and transforms.
Rollup: Do I need Rollup if I use Vite?
Not directly. Vite uses Rollup for production builds, so you already benefit from it.
