Show HN: Serif – a zero-dependency, DataFrame for Python https://ift.tt/xF16VkD

Show HN: Serif – a zero-dependency, DataFrame for Python OP here. I built this library out of frustration with messy, day-to-day data: CSVs with duplicated columns, APIs returning nested JSON, Excel sheets, and various ad-hoc ETL requests. Tools like Polars and DuckDB are great for heavy analytical workloads, but sometimes I just want a lightweight, Pythonic table I can iterate over. I want the ability to for `row in table:` without surprising semantics. Serif takes a vector-first, zero-dependency approach aimed at everyday data tasks. https://ift.tt/bKLnj7R This is an early release, so I'm looking for feedback on ergonomics and places where the API is either missing features or could be simpler. https://ift.tt/bKLnj7R December 11, 2025 at 10:05PM
