Xorq is the company blog at xorq.dev, writing about data and ai. Since 2025, 3 different Hacker News readers have linked it 8 times, most often “Build an open source FeatureHouse in 300 lines of code”. No feed was found, so read it on the site itself.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers link these posts about Xorq, a Python-first, pandas-style pipeline and open compute catalog built on DuckDB, covering semantic layers, feature stores, and out-of-core processing of large datasets.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Put agents on your data. Stand behind the answers. Deterministic data work for AI agents, approved once by a person — every step runs as a real query on your warehouse and every result is human approved.

So, really its about higher-order semantics and as we move up the stack, we need richer expression to describe our world. Feature stores…
