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.

tabrelay

v0.1.4

Published

Run isolated browser tools through TabRelay

0High
0Medium
0Low

tabrelay

Command-line client for TabRelay. Drives one browser tab through the TabRelay bridge so a coding agent can screenshot, click, read, and audit a page without owning the browser.

Install

npm install -g tabrelay
tabrelay init

tabrelay init installs the bundled Agent Skills into every coding agent it finds on the machine (Claude Code, Codex CLI, OpenCode). Use --dry-run to preview and --dir <path> for an agent it does not know about yet.

Usage

Every bridge command needs the connection ID of the tab you selected in the TabRelay extension:

tabrelay --connection-id tab_… status
tabrelay --connection-id tab_… screenshot --out page.png

TABRELAY_CONNECTION_ID and TABRELAY_BRIDGE work as environment variables instead of flags. Run tabrelay --help for the full verb list.

How the binary is shipped

The native binary lives in a per-platform optional dependency (@tabrelay/linux-x64 and friends); npm installs only the one matching your OS and CPU. There is no postinstall download, so the install works under --ignore-scripts, private registries, and offline caches.

Supported: macOS arm64, macOS x64, Linux x64, Windows x64. On anything else, build the CLI from source and point TABRELAY_BINARY_PATH at the result.
