Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Algorithmic chiptune tracker — generate 4-channel retro songs instantly

Readme

zzfx-studio

npm license

ZzFX Studio is an algorithmic chiptune tracker that generates 4-channel retro songs instantly using pure math -- no samples, no AI. Built for indie game devs who need quick retro audio for game jams and chiptune hobbyists who enjoy the creative process. Available as a PWA, desktop app (npx zzfx-studio), or global install (npm i -g zzfx-studio).

Quick Start

Run it right now, no install needed:

npx zzfx-studio

Or install globally:

npm i -g zzfx-studio
zzfx-studio

Or use the PWA -- no install at all:

thejustinwalsh.github.io/zzfx-studio

Supported Platforms

| Platform | Architecture | |---|---| | macOS | ARM64 (Apple Silicon), x64 (Intel) | | Linux | x64, ARM64 | | Windows | x64 |

The correct binary is automatically selected when you install via npm. Platform packages are optional dependencies -- if your platform isn't supported, the install won't fail, you just won't get the desktop binary.

How It Works

The desktop app wraps the web app using Neutralino.js -- a lightweight alternative to Electron that uses the system's native webview. The result is a tiny binary that launches fast and doesn't ship a whole browser.

The music generation is entirely algorithmic: Euclidean rhythms, probability-weighted pattern templates, and scale-constrained note selection. All audio is synthesized in real-time using ZzFX and ZzFXM.
