With the release of Next.js 15, one of the most transformative changes is the introduction of Turbopack, a next-generation bundler designed to significantly improve build and development speeds. Turbopack, written in Rust, replaces Webpack and offers much faster builds, particularly for large applications, making it a central feature of this update.
Key Features of Turbopack:
- Faster Builds: Turbopack claims to be up to 700x faster than Webpack, drastically reducing build times even for complex, large-scale applications. This acceleration boosts development speed and productivity, particularly in environments that rely on frequent builds(
- Atomic Spin
- )(DEV Community
- ).
- Incremental Compilation: It supports incremental builds, meaning only the code that has changed gets recompiled, which speeds up both local development and production builds(
- DEV Community
- ).
- Rust Performance: Built in Rust, Turbopack leverages the language’s memory safety and concurrency features to provide lightning-fast performance without sacrificing reliability(
- Coding Beauty
- ).
- Seamless Integration: Turbopack is fully integrated into Next.js 15, working out of the box with
create-next-app, providing developers with a smoother setup and faster feedback during the development process( - Atomic Spin

The introduction of Turbopack sets a new benchmark for build performance in modern web development, making Next.js 15 an appealing upgrade for developers looking to optimize their workflow.
