Hacker News Show HN Launches Enriched Dataset
This dataset packages public Hacker News Show HN launch posts into a single analysis-ready dataframe with title normalization, external-domain enrichment, engagement metrics, author launch-history features, and product-category heuristics.
Each row represents one Show HN launch story retrieved from the public Algolia Hacker News Search API. The dataset adds normalized launch text, timestamp rollups, external URL parsing, domain-classification fields, launch-category labeling, maturity signals, keyword flags, and repeat-author history metrics. The result is easier to use for startup research, product-intelligence workflows, trend analysis, founder scouting, and developer-tool market research than manually collecting Show HN posts from raw API responses.
