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.

superduck

Your browser's session, callable as a tool.

superduck is a CLI that lets agents (Claude Code, Codex, etc.) read from and fetch as the user's currently-running Chrome — same login state, same cookies, same active tab.

Install

npm install -g superduck
superduck setup

Then in Chrome: install the SuperDuck extension, reload, and run:

superduck doctor

All green → you're ready.

Quick start

superduck context                       # see what the user is reading
superduck fetch https://api.example.com # using their cookies
superduck tabs

See SKILL.md for the agent-facing usage doc.

Architecture

agent CLI ──► superduck (this binary)
                 │ UDS /tmp/chrome-native-host.sock
                 ▼
              chrome-native-host (Go) ──Chrome Native Messaging──► SuperDuck extension ──► active tab

The native binary is shipped via npm optionalDependencies (one platform package per arch) so install never runs a postinstall download script.
