Y Recombinator is a discovery site that ranks Hacker News discussions and links by how often HN users recommend them to one another. Its list includes both full submissions and individual comments, with each entry showing its recommendation count, year, author, and original discussion. The ranking is therefore distinct from a conventional list of the most upvoted stories: a remark in a thread can outrank the thread itself if more people have singled it out as worth revisiting. Visitors can browse topics, inspect related recommendations from the same discussion, and explore past entries or comments.
The featured examples span Hacker News’s history and range across programming, startups, business, security, and culture. The most-recommended entry is a comment on Dropbox’s 2007 launch discussion, followed by the original Dropbox submission; other prominent picks include a question about winning the Putnam math competition, a report on the size of a codebase, a 2009 account of hacking Hacker News, and practical discussions of spare-time intellectual property and consulting. The list also surfaces technical explainers and essays, such as guides to documentation, SQLite hosting, mechanical watches, and programming as theory building, alongside stories about Uber, Theranos, Bitcoin, and Facebook’s Instagram acquisition. The collection uses Hacker News data and its API, with data current to November 3, 2026; it is unaffiliated with Hacker News and Y Combinator.
