About nichelib

nichelib builds narrow, spec-level databases for consumer-hardware industries and sells them as CSV/XLSX/JSON bundles. The point is not another market-size report — it is the auditable rows behind the market: model, component, price, compatibility and diagnostic data, each value traced to a public source page.

What we publish

Each vertical library normalises public product catalogs, official product pages, manuals and certification pages into one schema: brands, models, spec fields, error codes, chargers, compatibility and certification references. Every populated value carries a source URL, a verbatim quote from that source, the fetch time and a confidence label. Bundles ship with a data dictionary, a QA report and a reproducible manifest (input and file SHA-256).

How we work

Collection is robots-respecting and public-page only. Extraction is deterministic first; missing values stay null rather than being guessed. Datasets declare a quality tier (inventory, lite or survey) and their price and spec coverage in the dataset card, so a buyer can see exactly what is complete before purchasing. Quarterly refreshes publish a change log with added, removed and price-changed records.

Who it is for

Brand and category managers, distributors, repair shops, marketplace sellers and analysts who need a spreadsheet they can filter and cite — not a PDF narrative. Collections and custom slices are available on request.
