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

optrex (Cornea npm installer)

npm license MCP Tawakkul Labs

Installs the prebuilt Cornea binary for your platform and exposes the cornea command. Cornea is deterministic visual inspection for AI agents: overlap, overflow, contrast and quality as token-cheap geometry instead of pixel dumps. No Chromium.

npm install -g optrex
cornea --help

On install, the matching binary is downloaded from GitHub Releases into the package bin/ folder. No Rust toolchain needed.

Supported platforms

| OS | Arch | Asset | |----|------|-------| | Linux (glibc) | x64 | cornea-x86_64-unknown-linux-gnu | | Linux (glibc) | arm64 | cornea-aarch64-unknown-linux-gnu | | macOS | arm64 | cornea-aarch64-apple-darwin | | macOS | x64 | cornea-x86_64-apple-darwin | | Windows | x64 | cornea-x86_64-pc-windows-msvc.exe |

Not listed, e.g. Android, or musl/Alpine: the installer stops with a clear error. Install from source instead (cargo install cornea) or pick a build from the releases page.

Usage

Same as the native binary:

cornea page.html 360
cornea --serve   # MCP server over stdio for agents

Versions

npm package version tracks the Cornea release version. [email protected] installs Cornea 0.2.2.

Uninstall

npm uninstall -g optrex

License
