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

Svelte

  • Licensed under the MIT License per svelte.dev; as open source software it has no paid tier or vendor price to compare
  • Svelte is a compiler rather than a runtime library by design, per svelte.dev, so components must be compiled ahead of time and cannot be interpreted directly in the browser without a build step
