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 🙏

domn8n

AI-powered DOM mapper that generates standalone Playwright automation scripts.

Give it a URL and a goal. It opens a browser, uses Claude to figure out each page, fills forms, clicks buttons, and when it's done — spits out a standalone Playwright TypeScript script you can run without domn8n.

Install

npm install -g domn8n

You'll also need Playwright's browsers:

npx playwright install chromium

Usage

domn8n --url "https://example.com" --goal "Log in and navigate to billing"

On first run, it will ask for your Claude API key (saved to ~/.domn8n/keys/).

What happens

  1. Opens a visible Chromium window
  2. Claude interprets each page and decides what to do next
  3. Prompts you in the terminal when it needs input (credentials, form values, CAPTCHAs)
  4. Retries up to 3 times per step if something fails
  5. Saves a standalone Playwright .ts script to ~/.domn8n/scripts/

Output

The generated script is a plain Playwright TypeScript file with zero dependency on domn8n. Sensitive values (passwords) are read from environment variables:

DOMN8N_PASSWORD=secret npx tsx ~/.domn8n/scripts/example-com-login.ts

Security

  • Passwords and secrets are never sent to the AI — only field labels and types
  • Sensitive inputs are prompted with hidden input in the terminal
  • Generated scripts read credentials from env vars, never hardcoded
  • API key stored with 0600 permissions

How it works

Three layers:

  • Explorer — Extracts a simplified DOM snapshot (interactive elements, forms, links) and captures network calls
  • Pilot — Sends the snapshot to Claude, which returns the next action as structured JSON
  • Recorder — Logs every action and generates a standalone Playwright script at the end

Development

git clone https://github.com/AbhinavMir/domn8n
cd domn8n
bun install
bun run src/cli.ts --url "https://example.com" --goal "your goal"
