Git Commit Emails Extractor (Apify Actor)

Extract commit emails from one or more Git repositories and aggregate commit counts per email.

What this actor does

• Accepts multiple repositories as input.
• Supports:
  • GitHub URL (https://github.com/owner/repo)
  • Git URL (git@github.com:owner/repo.git)
  • GitHub shorthand (owner/repo)
• Reads commit history from HEAD.
• Outputs:
  • Dataset rows with commit-email aggregates (one row per email, no type field)
  • Repository summaries in key-value store under OUTPUT

Input

{
"repositories":[
"https://github.com/<user>/<repository>"
],
"excludeNoReply":true,
"normalizeEmails":true,
"includeAuthorAliases":true
}

Input fields

• repositories (required): list of repositories to process.
• excludeNoReply (optional, default false): exclude *@users.noreply.github.com and *@noreply.*.
• normalizeEmails (optional, default true): lowercase emails before grouping.
• includeAuthorAliases (optional, default true): include all author names seen for each email.
• branch (optional): branch name used when cloning remote repositories. If the branch does not exist in a repository, the actor automatically falls back to that repository's default branch.

Notes

• If contributors use masked emails (for example GitHub noreply), the actor cannot infer private real emails.
• Large repositories can produce large datasets.
