What people use each for
The jobs each tool is most often brought in to do.
Rollup
- Publishing a JavaScript library in several module formatsnot Yarn
- Builds where output size and cleanliness matter more than build speednot Yarn
- Producing ES module output for consumers who will bundle it themselvesnot Yarn
Yarn
- Monorepo teams managing dependencies across 50+ interdependent packagesnot Rollup
- Enterprise JavaScript projects ensuring reproducible builds across CI/CDnot Rollup

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
Yarn
- Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
- Smaller ecosystem and community compared to npm, though still substantial

Answered from the vendors’ own pages
Rollup: Is Rollup free?
Yes, open source under the MIT licence.
Yarn: What is Yarn's main advantage over npm?
Yarn downloads packages in parallel, significantly reducing installation time. It uses a yarn.lock file for deterministic installs, ensuring identical package versions across machines and preventing version conflicts common with npm.
SourceRollup: 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.
Yarn: Can I use Yarn in offline environments?
Yes, Yarn supports secure offline environments. The yarn.lock file enables reproducible installs without requiring new downloads.
SourceRollup: Do I need Rollup if I use Vite?
Not directly. Vite uses Rollup for production builds, so you already benefit from it.
