Common Crawl: coverage and access

What it covers

Geography and granularity

Geography: Use the geography stated by the source; coverage can vary by dataset and release.

Granularity: Study public documentation, pricing pages, changelogs, ecosystem pages, and historical web presence at scale; build searchable or longitudinal datasets from public web snapshots.

Source type: Open web-crawl corpus/index

Potential use

Study public documentation, pricing pages, changelogs, ecosystem pages, and historical web presence at scale; build searchable or longitudinal datasets from public web snapshots. Especially useful for developer-tool founders doing competitive intelligence and documentation/ecosystem research without relying on excluded search or social platforms.

Access and cost

Public download

Free/open corpus access; crawl files and indexes are distributed for download/query, with technical examples documented by the Foundation.

Cost: The source describes public or free access; confirm any API, bulk-download, and reuse terms directly.

Update cadence: Release cadence was not normalized in this review; check the source's dates, update notes, and API limits before comparing periods.
