AppKaiju

Finding Monster New Apps & Sales

Launched at the beginning of 2019, AppKaiju is a friendly monster that searches the Internet, finding the best apps and sales! In 2018 Apple cancelled the primary funding source for sites that catalog apps... about halfway through the development of AppKaiju. I decided to finish the site out of pure spite for Apple. They defunded cataloging sites to push developers to pay for search advertising, so I'd make sure mine kept going without funding. I needed a site like it to keep up with the news on discchord anyhow, and existing cataloging sites were starting to show signs of breaking.

Technical Details


AppKaiju was coded and designed in Python, using Flask. The JavaScript is entirely custom, without any frameworks. I used Angular as the JS Framework on discchord and didn't like how bloated it was. I decided to do the JS for AppKaiju entirely on my own! The project began in April 2018, and the site launched February 2019. More than half of that time was spent on the crawler and popularity algorithms, which I continue to tweak after launch. The site's database is running on a MongoDB cluster that I also manage.

The site finds the goodies with crawlers that reside on 7 servers spread across the globe. They're named after the Seven Dwarfs from Snow White, by their apparent personalities. Doc is the most reliable, while Dopey is constantly getting into trouble. Grumpy throws random tantrums and errors at me. Together they are shepherded by AppKaiju's primary logic; forever seeking new apps around the clock. The crawlers were also written in Python.
