Andrey Karpaty created a YouTube analogue in two hours based on Hacker News recommendations. Claude filtered 43 million comments for this

He said this on his X account.

HackerTube videos contain content shared by Hacker News users over the past 20 years, and Karpaty used Claude to filter 43 million Hacker News user comments into 6,454 recommended videos to create the site. In doing so, he created an alternative to YouTube’s recommendation algorithm.

At the same time, according to Karpaty himself, it took him about two hours and the help of Claude Opus 5.5 to implement the project.

The well-known programmer only performed a few tasks himself, including setting up a Google Cloud API key, VPS, and purchasing a domain. Claude handled the coding, deployment, security, and optimization.

HackerTube doesn’t require a login, avoids clickbait thumbnails by using video footage, and allows users to upload basic recommendation data.

In this context, Karpaty claims that projects that previously took weeks or months can now be created in one morning.
