hackertubeguideHackerTube Guide
A short reference to what HackerTube is, how its public data was assembled, and where builders can take the idea.
Quick answer
HackerTube is Andrej Karpathy's video discovery site built from YouTube links recommended in Hacker News comments. Its author offers a public data export for new projects. This independent guide is not the original site, and the export is not a ready-to-use website.
What is HackerTube?
In the initial collection described by Karpathy in October 2026, 6,454 videos appeared across 150 topics. The recommendations came from Hacker News discussions spanning 2007 to 2026. HackerTube organizes them for discovery and links viewers to the underlying YouTube videos.
How it was built
- Collect the signal
- Hacker News comments containing YouTube links supplied the starting material.
- Filter recommendations
- a Sonnet workflow in Claude Code screened comments and removed spam, according to Karpathy.
- Add metadata and browsing
- YouTube API metadata helped turn selected links into a topic-based discovery site.
What is public?
- Data export
- the author says site data is available to export and use as a starting point.
- Website implementation
- a data export is not a finished website or bundled code kit.
- External content
- videos, thumbnails, metadata and comments have their own source and usage rules.
Build with the idea
Start with a small, traceable discovery task. A useful first release can be a clear list, a detail page for each result, and a reliable path back to the source.
- Define one audience and one task.
- inspect the export, source links and current usage terms.
- make every list item lead to a traceable detail page.
- check broken links, attribution and claims before publishing.
FAQ
Can I reuse the public data?
The author offers an export; check its current terms and the rules for linked media before reuse.
Is this the official HackerTube site?
No, hackertubeguide is an independent guide and project directory.
Do all six listed projects use the same data?
No; their relationships differ, and some adapt the Hacker News discovery method.
