HackerTube vs YouTube: what changes when the algorithm is Hacker News

	YouTube	HackerTube
Catalog	Everything uploaded	6,454 videos that cleared a public, stated bar
What ranks a video	Predicted watch time and clicks for you, specifically	How many different months HN users recommended it, 2007–2026
Thumbnail	The uploader's custom image	A frame from the middle of the video
Why you see it	Not explained	The actual comments, with links to the threads
Accounts	Required for history, likes, subscriptions	None; your list lives in your browser
Tracking	Extensive	Privacy-enhanced embed; no analytics tied to you
Freshness	Real time	Slow by design; a video needs months of recommendations to enter
Blind spots	Whatever you have not clicked on yet	Whatever HN does not talk about: most non-English content, most entertainment, most music
Who it is for	Everyone	People who read HN, or wish their feed did

What HackerTube is better at

Finding the talk you will still be thinking about next year. The three-people, three-months rule means every video has been vouched for by strangers who had no stake in your watch time, repeatedly, over time. The middle-frame thumbnails remove the thumbnail arms race entirely. And the "why" is on the page: you can read exactly what people said before you commit an hour.

What YouTube is better at

Almost everything else: breadth, recency, non-technical subjects, non-English content, music, live events, a channel you already follow. HackerTube is a filter, not a catalog. It is also a snapshot of one community's taste: strong on software, mathematics, physics, urbanism, computing history and conference talks; thin on most of what the rest of the world watches.

Where this edition sits

HackerTube Watch is the same list with a page for every video, topic and channel, the HN comments shown inline, a few extra ranked views, and a pipeline to add new recommendations after the original export. If you want the original interface, with playlists and semantic search, it is at hackertube.org.

Questions

Is HackerTube a YouTube replacement?

Not for everything. It is a replacement for the YouTube home page and its recommendations. The videos still play from YouTube, through the privacy-enhanced embed, and nothing here hosts video.

Does HackerTube have everything YouTube has?

No, and that is the point. YouTube has hundreds of millions of videos; HackerTube has 6,454, chosen because at least three Hacker News users recommended each one in at least three different months.

Which should I use?

Use YouTube to find a specific video or a channel you already follow. Use HackerTube when you have an evening and want something that people you would probably respect kept recommending for years.
