What is the main advantage of Turbopack over other bundlers?

Turbopack's main advantage is its incremental architecture, which provides the fastest possible dev experience on large projects. It does not rebuild the entire application on every change, instead updating only the affected modules, using deep caching and parallel processing.

#What this advantage gives you

• instant HMR even on large codebases
• minimal response time after any change
• no "uniform slowdown" as the project grows (unlike Webpack and even Vite)

---

#Why this matters

Other tools work on a model where the build, or part of it, is repeated from scratch (even if optimized). Turbopack, on the other hand, builds the project's graph once, caches it, and then recalculates only the changed nodes. This makes it scalable: the bigger the project, the more noticeable the advantage.

Summary: Turbopack's main advantage is incremental building with continuous caching, which keeps development speed high regardless of project size.
