gh-enterprise-contribution-sync

A GitHub CLI extension that syncs your GitHub Enterprise Server contribution graph to GitHub.com — without leaking any enterprise data.

It fetches your GHES contribution calendar, creates backdated empty commits in a local repo, and pushes to a private GitHub.com repo. Your enterprise contributions then appear on your public profile.

Install

gh extension install balcsida/gh-enterprise-contribution-sync

Requires GitHub CLI authenticated to both your GHES instance and GitHub.com:

gh auth login --hostname github.example.com
gh auth login --hostname github.com

Usage

gh enterprise-contribution-sync

That's it. On first run it will:

1. Auto-detect your GHES host, username, and account creation date
2. Fetch your full contribution history (chunked into 1-year API windows)
3. Create backdated empty commits via git fast-import
4. Create a private enterprise-contributions repo on GitHub.com
5. Push

Subsequent runs sync incrementally — only new contributions since the last run.

Preview

gh enterprise-contribution-sync --dry-run
