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 🙏

Readme

neat.is

NEAT keeps a live semantic graph of a software system — code, infrastructure, runtime — and exposes it to AI agents over MCP.

Prerequisites

  • Node.js 20 or newer. Enforced via engines; older versions fail at install.
  • A C toolchain, because @neat.is/core builds native bindings for tree-sitter (JS, TS, Python parsers) at install time:
    • macOS: Xcode Command Line Tools (xcode-select --install)
    • Debian/Ubuntu: build-essential plus python3 (for node-gyp)
    • Alpine: build-base python3
    • Windows: Visual Studio Build Tools with the "Desktop development with C++" workload

If npm install -g neat.is fails partway through with a gyp error, the toolchain is the cause. Install it and re-run.

Install

npm install -g neat.is

That puts three binaries on your PATH:

  • neat — CLI (init, watch, list, skill, plus the nine query verbs that mirror the MCP tool surface)
  • neatd — daemon (start, stop, status, reload)
  • neat-mcp — MCP stdio server for Claude Code and other agents

Quick start

neat init /path/to/your/repo --project myrepo
neatd start

Snapshot lands at <repo>/neat-out/myrepo.json. The daemon watches for file changes and OTel traces (:4318 HTTP by default) and keeps the graph live.
