Compatible Zig Version: 0.14.0

Compatible tardy Version: v0.3.0

Latest Release: 0.3.0

zig fetch --save git+https://github.com/tardy-org/zzz#v0.3.0

You can then add the dependency in your build.zig file:

const zzz = b.dependency("zzz", .{
    .target = target,
    .optimize = optimize,
}).module("zzz");
exe.root_module.addImport(zzz);

zzz is a framework for writing performant and reliable networked services in Zig. It supports both HTTP and HTTPS.

zzz currently supports Linux, Mac and Windows. Linux is currently the recommended target for deployments.

It focuses on modularity and portability, allowing you to swap in your own implementations for various things. Consumers can provide an async implementation, allowing for maximum flexibility. This allows for use in standard servers as well as embedded/bare metal domains.

For more information, look here:

zzz is very fast. Through a combination of methods, such as allocation at start up and avoiding thread contention, we are able to extract tons of performance out of a fairly simple implementation. zzz is quite robust currently but is still early stage software. It's currently been running in production, serving my site.

With the recent migration to tardy, zzz is about as fast as gnet, the fastest plaintext HTTP server according to TechEmpower, while consuming only ~22% of the memory that gnet requires.

Raw Data

Raw Data

On the CCX63 instance on Hetzner with 2000 max connections, we are 70.9% faster than zap and 83.8% faster than http.zig. We also utilize less memory, using only ~3% of the memory used by zap and ~1.6% of the memory used by http.zig.

zzz can be configured to utilize minimal memory while remaining performant. The provided minram example only uses 256 kB!
