TL;DR
Buz is a new project that forks Bun, a JavaScript runtime, using the Zig programming language. It achieves sub-one-second incremental build times, potentially transforming developer productivity.
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 development could significantly speed up JavaScript and web development workflows, according to its creators.
Developed by a team of open-source contributors, Buz aims to leverage Zig’s modern features to optimize build performance. The project is still in early stages but has demonstrated impressive speed improvements over existing runtimes. The key feature is its ability to perform incremental builds in less than a second, a milestone that could reduce development iteration times dramatically. The project’s creators emphasize that Buz remains compatible with existing Bun workflows, but it is not yet clear how mature or stable the implementation is. The initiative has garnered attention from developers interested in performance optimization and alternative runtimes for JavaScript and web development.Potential Impact on JavaScript Development Speed
This development matters because faster build times directly translate into increased productivity for developers. By reducing incremental build times to under one second, Buz could enable more rapid testing, iteration, and deployment cycles. If adopted widely, it could challenge existing runtimes like Node.js and Bun, encouraging further innovation in runtime design and build optimization. Additionally, the use of Zig, a modern language known for its performance and safety, may influence future runtime development trends. Overall, Buz’s speed improvements could reshape expectations for development efficiency in the JavaScript ecosystem.

Background on Bun and Zig’s Role in Runtime Development
Bun is an open-source JavaScript runtime that has gained popularity for its speed and modern features. It is built using JavaScript and C++, aiming to provide faster startup and execution times compared to Node.js. Zig, a low-level programming language designed for performance and safety, has been increasingly adopted for systems programming and performance-critical applications. Buz’s development as a Zig-based fork of Bun reflects a broader trend of exploring alternative languages and architectures to optimize runtime performance. Prior efforts in this space have focused on improving build times and runtime efficiency, but achieving sub-one-second incremental builds remains a rare milestone. The Buz project is still in early testing phases, with community interest growing around its potential to accelerate web development workflows.“Our goal was to leverage Zig’s modern features to drastically reduce build times. Achieving sub-one-second incremental builds is a significant step forward.”
