Copycat

Extension to test web apps without writing a line of code

Copycat launched on November 1, 2019 with 120 votes, #221 of 3,203 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 6 years on.

What it does

This extension is built to ease creating web tests. It is like Selenium-IDE, but for jest-puppeteer (for now). Also, this extension records actions on your browser, so it doesn't need to open up a new Selenium or Puppeteer window to record your actions on it.

    Autotab is a Chrome extension that writes Selenium code to mirror your actions as you navigate the browser. See it in action: https://youtu.be/UypAcozIaoo Autotab lets you create browser automations that actually work. We designed it around two principles: 1. Show, don’t tell: In a domain like web automation, it's often easier to *show* the model what you want rather than to explain it in sentences. 2. Code is the best output: Code is easy to inspect and enables manual tweaking of the model’s suggested actions. On top of that, code output avoids lock in and is straightforward…

  • Talanoa▲340

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
