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

Your AI QA engineer, with memory. Describe a user journey in plain language. agent-qa tests it on web, Android or iOS and keeps the evidence. Use the CLI, the dashboard, or your coding agent through MCP and skills.

  • memidex: remembers facts and working procedures as reviewable files in your repository.
  • Self-improvement: validates lessons from runs, retires stale knowledge, and uses your feedback to correct mistakes.

| Benchmark | Rank | Published result | | --- | --- | --- | | AndroidWorld | #1 | 100% pass@1 (116/116 tasks) | | AppControlBench | #1 | 99.6% completion (114.5/115 points) |

Read the full benchmark reports, with run evidence and methodology, on our blog. Both used gpt-6-sol with memory and self-improvement off; AppControlBench gives half credit for partial completion.

See it in action

Inspect a failure. The demo catches a cart showing $29 instead of $53, with the failed step and its screenshot side by side.

See what memory contributed. Inspect the knowledge supplied to a run and trace it back to the steps that used it.

Run from your terminal. Real output from the demo suite: checkout passes; the deliberate cart-total bug fails.

Get started

Requires Node.js 24+.

npm install -D agent-qa
npx agent-qa init

Follow the quickstart to connect a model and run the demo, or set up with your coding agent.
