TL;DR
Buz is a new software project that forks Bun, utilizing the Zig programming language to achieve incremental build times of less than one second. This development aims to improve build efficiency and developer productivity.
Buz, a new project forked from the JavaScript runtime Bun, has achieved incremental build times under one second by leveraging the Zig programming language, according to its developers. This milestone could significantly enhance developer workflows by reducing build latency, making it a notable development in the JavaScript and build tool ecosystems.
The Buz project was created as a fork of Bun, an increasingly popular JavaScript runtime focused on performance. Unlike Bun, which is primarily written in JavaScript and C++, Buz is built entirely using Zig, a modern systems programming language known for its efficiency and explicit control over memory management. According to the Buz development team, this choice of language has enabled them to optimize build processes, resulting in incremental build times of less than one second for typical projects. The project was publicly announced in March 2024, with the developers emphasizing that the primary goal was to improve build speed and developer productivity. They demonstrated that, with Buz, incremental builds are completed in under a second, a significant improvement over traditional JavaScript-based build tools, which can take several seconds or more for large projects. The Buz team states that their approach involves re-architecting parts of Bun’s build system in Zig, allowing for more direct hardware access and efficient memory handling. This technical shift is claimed to reduce build latency dramatically, especially in iterative development workflows where frequent rebuilds are necessary. The project remains in early stages but has garnered attention for its promising performance benchmarks and potential to influence future build tool development.Performance Impact on JavaScript Development Workflows
The achievement of sub-1 second incremental build times with Buz could transform how developers approach project iteration and testing. Faster builds mean less waiting and more rapid experimentation, particularly valuable in large codebases or complex projects. If adopted widely, Buz’s performance improvements could set new standards for build tools in the JavaScript ecosystem and beyond, encouraging further innovation in systems programming languages like Zig for performance-critical applications.

Background on Bun and Zig’s Role in Build Optimization
Bun is an emerging JavaScript runtime designed for speed and efficiency, gaining popularity among developers for its fast startup and execution times. It is primarily built using JavaScript and C++, aiming to replace Node.js in many scenarios.
The Zig programming language is a relatively new, low-level language focused on performance, safety, and simplicity. It offers direct hardware access and predictable memory management, making it suitable for systems programming and performance-critical applications. Several projects have explored Zig as an alternative to C or C++, but its adoption in build tools remains limited.
The Buz project’s use of Zig to re-implement parts of Bun’s build system is a novel approach, aiming to leverage Zig’s performance advantages to reduce build times significantly. This development builds on prior efforts to optimize build processes but is among the first to report such rapid incremental build times using Zig in a JavaScript runtime context.
“Our goal was to re-architect Bun’s build system in Zig to achieve sub-second incremental builds, and we are excited to demonstrate that it is possible.”

Unconfirmed Aspects of Buz’s Development and Adoption
Details about Buz’s stability, compatibility with existing Bun projects, and long-term maintenance are still emerging. It is not yet clear whether Buz will be adopted broadly or how it compares in real-world scenarios beyond initial benchmarks. Additionally, the extent to which Zig’s advantages translate into other aspects of build tooling remains to be seen, and the project is still in early development stages.
