The 10 Best Systems Software Datasets in 2026

10 Systems software picks, ranked on what's inside: field richness, coverage depth, fit for the job. crates.io - Rust Package Registry API leads.

  • 10ranked picks

API, files, or your warehouse. Daily, weekly, or hourly.

Every dataset here carries a 0–10 score built on documented fields, and the ranking follows those scores. When records tie, coverage breaks it: more geography, deeper history, finer granularity. Cadence isn't a scoring axis — it's a delivery setting. Delivered daily, weekly, or hourly, your call.

    PyPI - Python Package Index API and Stats

    Why it ranks fifth: the cleanest growth-curve substrate in the slice, trading nested depth for scanability.

    endoflife.date Product Lifecycle Catalog

    name · label · category …+9 more

    Why it ranks eighth: narrow by design and deep where roadmaps live, with CPE-style identifiers that tie straight into the NVD records above it.

  9. 9 9/10
    Systems software

    GitHub Octoverse and GitHub REST/GraphQL API

    Why it ranks ninth: unmatched currency, held back only by a seven-field documented summary that asks you to do more interpretive work per row than the registries demand.

  10. 10 9/10
    Systems software

    Repology - Packaging Hub

    Why it ranks tenth: a derived consensus rather than a primary record - superb for spotting divergence between distributions, secondhand for anything provenance-sensitive.

Frequently asked questions

How far ahead do software end-of-life schedules reach?

Years, product by product: endoflife.date grades 464 products on a staircase of releaseDate, eoasFrom, eolFrom and eoesFrom fields. Ubuntu 26.04, for example, carries standard support to 2031-04-30 and extended coverage to 2036-04-30 - a decade of planning horizon in one row.

Where does operating system market share history come from?

StatCounter GlobalStats holds monthly OS share worldwide, across six regions and by country from January 2009 to the present. W3Techs covers the server side with its Unix-family versus Windows split, and Valve's Steam Hardware Survey adds monthly GPU, VRAM and CPU-core distributions from the gaming installed base.

Does Datadory resell these publishers' records or build on them?

Datadory delivers the records these publishers maintain - normalized schemas, typed columns, documented fields and stable join keys, with sample rows before commitment. The package, vulnerability, language and geography spines are pre-aligned across corpora, so a join that would take weeks of plumbing arrives already holding together.
