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 🙏

appcrawl

v0.2.1

Published

AI-powered app testing. Let an LLM explore and test your mobile or web app autonomously. Bring your own API key.

Readme

npm license


What it does

# Let AI explore your app autonomously
appcrawl explore --app com.example.app

# Or steer it with natural language
appcrawl run "sign up, verify email, reach dashboard"

# Extract explore sessions to replayable YAML suites
appcrawl extract --from appcrawl-reports/latest

# Run suites in CI with parallel execution
appcrawl suite tests/ --parallel 4 --notify-slack $SLACK_WEBHOOK

AppCrawl runs an LLM agent (Claude, GPT-4o, Gemini, Ollama, ...) against your iOS simulator, Android emulator, or a Playwright-driven browser. The agent sees screenshots + the accessibility tree, picks actions (tap, type, scroll, verify), and logs anything that looks wrong.

Features

  • Mobile + web — iOS via Maestro, Android via adb, web via Playwright
  • BYO LLM — Claude / GPT-4o / Gemini / Ollama / OpenRouter
  • Explore mode — autonomous bug-hunting with breadth-first screen coverage
  • Steered mode — natural-language E2E tests, no selectors
  • Suite runner — YAML-defined tests, parallel execution
  • Test extraction — convert explore sessions to replayable suites
  • Visual regression — pixel-diff screenshots against baselines
  • GitHub Action — drop-in composite action with PR comments
  • Static HTML dashboard — deploy reports to any static host
  • Slack + webhook notifications — know the moment something breaks

Install

npm install -g appcrawl

Requires Node 20+. For iOS testing also install Maestro; for web testing run npx playwright install chromium.
