TL;DR
Buz is a new project that forks Bun using Zig, resulting in incremental builds that complete in under one second. This development could significantly speed up JavaScript/TypeScript development workflows.
Buz, a new fork of the JavaScript runtime Bun built entirely with the Zig programming language, has achieved incremental build times under one second. This milestone was announced in March 2024 and aims to enhance developer productivity by significantly reducing build latency.
According to the Buz project team, the fork leverages Zig’s modern features to optimize build processes, resulting in sub-1s incremental builds. The project is designed to be compatible with Bun’s API, allowing developers to adopt it without major code changes. Buz’s core innovation lies in its use of Zig to streamline the build pipeline, which traditionally has been a challenge for JavaScript runtimes focused on performance and startup time. The project’s creators emphasize that this performance gain could lead to faster development cycles, especially in large codebases where build times are a bottleneck. While Buz is still in early development, initial benchmarks indicate promising results, with some tests showing build times reduced by an order of magnitude compared to existing solutions. The project is open-source and actively seeking community feedback to refine its features and compatibility.Impact of Sub-1-Second Incremental Builds on Development
This development matters because reducing build times can dramatically improve developer productivity, especially in large-scale projects. Faster incremental builds mean developers spend less time waiting and more time coding or testing, which can accelerate project timelines and reduce frustration. Additionally, Buz’s approach demonstrates that using Zig—a modern, low-level language—can be viable for high-performance runtime development, potentially influencing future JavaScript engine designs. If adopted widely, Buz could challenge existing runtimes like Node.js and Deno by offering faster build and startup times, which are critical in modern development workflows. However, it remains to be seen how well Buz will integrate into existing ecosystems and whether it can maintain compatibility at scale.

Bun, Zig, and the Evolution of JavaScript Runtimes
Bun has gained popularity as a high-performance JavaScript runtime aimed at replacing Node.js with faster startup and build times. It is written in Zig, a language known for its performance and simplicity, and has attracted developers seeking speed improvements. The idea of using Zig for runtime development is not new but has gained traction with Bun’s success. Buz emerges as a fork of Bun that takes a different approach by re-implementing core features with an emphasis on ultra-fast incremental builds. This effort is part of a broader trend of optimizing JavaScript tooling for modern development needs, where build latency can significantly impact productivity. The project was announced in early 2024, with initial benchmarks indicating promising performance gains. While Bun itself continues to evolve, Buz’s focus on build speed highlights ongoing innovations in runtime engineering, leveraging Zig’s capabilities to push performance boundaries further.
“Using Zig allowed us to optimize the build pipeline to achieve under one second incremental builds, which was not feasible with traditional approaches.”

Uncertainties About Buz’s Compatibility and Adoption
It is not yet clear how well Buz will integrate with existing JavaScript ecosystems or how mature the project is for production use. The current benchmarks are promising but limited in scope. Compatibility with popular libraries and frameworks remains to be tested at scale. Additionally, community adoption and support will influence its long-term viability. Further testing and feedback are needed to confirm whether Buz can replace or complement existing runtimes in real-world scenarios.

Key Questions
What is Buz and how does it relate to Bun?
Buz is a fork of the JavaScript runtime Bun, built using the Zig programming language, with a focus on achieving ultra-fast incremental build times.
Why is Zig used in Buz’s development?
Zig offers low-level control and performance advantages, enabling Buz to optimize its build pipeline and achieve sub-one-second incremental builds, which are difficult with other languages.
Can Buz replace Bun or Node.js?
It is too early to say whether Buz can fully replace Bun or Node.js. Currently, it is in early development, and compatibility and ecosystem support are still being tested.
What benefits does Buz offer to developers?
The primary benefit is significantly faster build times, reducing developer wait times and potentially accelerating project workflows.
Is Buz ready for production use?
At this stage, Buz is experimental, and more testing is needed before it can be considered stable for production environments.
