How we picked these peers
Peers are the 5 sources with the smallest absolute distance to GitHub on the composite SourceScore Index, across all platform and non-platform sources. Distance is computed as |peer Index − GitHub Index|. Ties are broken by higher Index first, then alphabetical by name.
Distinct from GitHub's curated comparator hub, which lists hand-selected head-to-head pairs. Peers is auto-computed from the score data — every source has one, and it surfaces neighbors regardless of editorial selection.
