ZWS - Minimalist Web Server

February, 28 2026. 5 minutes read.



Introducing ZWS, a minimalist, multi-threaded web server written in Zig.

Designed to mimic the simplicity and application-serving nature of uWSGI, ZWS serves as both a functional web server and an educational tool. It handles multiple connections concurrently using Zig's standard library, making it a great resource for learning about systems programming and web server architecture.



Key Features of ZWS:

  • Multi-threaded: Handles multiple connections concurrently using std.Thread.
  • Minimalist: Built using only the Zig Standard Library (std.net, std.Thread).
  • Educational: Every line of code is commented to explain the concepts.
  • Application Container: Simulates an application entry point, similar to how uWSGI runs apps.



To get started, you'll need Zig (0.13.0 or later). You can clone the repository and build it easily:

git clone https://github.com/hepidad/zws.git
zig build run



ZWS is designed as a foundation. You can extend it to serve Python applications, frontend SPAs, or JSON APIs. Check out the GitHub repository for more details and deployment guides.
