TL;DR
Buz is a new project that forks Bun using the Zig programming language. It has achieved sub-one-second incremental build times, potentially transforming JavaScript and TypeScript development workflows. The project is still in early stages, with further testing needed.
Buz, a new open-source project that forks the JavaScript runtime Bun using the Zig programming language, has achieved incremental build times under one second. This performance milestone could significantly enhance developer productivity by reducing wait times during development cycles.
The project, initiated by independent developers, aims to leverage Zig’s modern features for improved performance and maintainability. According to the Buz team, their implementation has demonstrated build times below one second during initial tests, a notable improvement over existing JavaScript runtimes. While Bun itself is known for fast startup and build speeds, Buz’s focus on Zig allows for more granular control over the build process and potential for further optimization. The project remains in early development, with ongoing testing to confirm stability and compatibility across different environments. The developers have shared that Buz is designed to be a drop-in replacement or extension of Bun, with the goal of providing a faster, more efficient toolchain for JavaScript and TypeScript projects.Potential Impact on JavaScript and TypeScript Development
Achieving sub-one-second incremental builds could revolutionize how developers interact with JavaScript and TypeScript codebases. Faster build times reduce waiting periods, enabling quicker testing, iteration, and debugging. If Buz proves stable and compatible, it could challenge existing runtimes like Node.js and Bun, especially in large projects where build speed is critical. This development also highlights the growing interest in using Zig for performance-critical applications, potentially influencing future runtime designs.

Background on Bun and Zig’s Role in Runtime Development
Bun is a modern JavaScript runtime known for its speed and efficiency, gaining popularity as an alternative to Node.js. It emphasizes fast startup, build, and execution times. Zig is a relatively new systems programming language designed for performance and safety, gaining traction for its simplicity and control. Developers have explored using Zig to build or enhance runtimes, citing its potential for low-level optimization and ease of integration. Buz’s development reflects this trend, aiming to combine Bun’s features with Zig’s performance advantages. The project’s early demonstrations suggest that Zig could play a significant role in next-generation JavaScript runtimes, especially for build performance improvements.
“Our goal with Buz is to push the boundaries of build speed, and achieving sub-1 second incremental builds is a major step forward.”
