A Go-based GitHub Action that mirrors repositories to multiple Git hosting providers — GitLab, GitHub, Bitbucket, AWS CodeCommit, and more — in a single step.
- Multi-target mirroring in a single workflow step
- Auto-detect provider from URL (GitLab, GitHub, Bitbucket, CodeCommit)
- Selective branch mirroring or mirror all branches
- Exclude specific branches from mirroring
- Tag mirroring support
- Force push option for exact replication
- Multiple authentication methods (token, app password, SSH key)
- Parallel mirroring to multiple targets concurrently
- Retry logic with configurable count and delay
- Dry run mode with remote connectivity pre-check (
git ls-remote) - JSON result output for downstream steps
- Credential masking in all log output

Targets are specified one per line. You can explicitly set the provider or let it auto-detect from the URL:
provider::url # explicit provider
url # auto-detect from URL
| Provider | Auth Method | Example URL |
|---|---|---|
gitlab |
OAuth2 token | https://gitlab.com/org/repo.git |
github |
x-access-token | https://github.com/org/repo.git |
bitbucket |
Username + App password | https://bitbucket.org/org/repo.git |
codecommit |
IAM / credential-helper | https://git-codecommit.us-east-1.amazonaws.com/v1/repos/repo |
generic |
SSH key or URL as-is | git@custom-git.example.com:org/repo.git |
Many teams need to keep repository mirrors in sync across multiple Git providers — for disaster recovery, CI/CD across platforms, compliance, or migration. This action replaces fragile shell scripts with a single, configurable step that handles authentication, branch/tag selection, and multi-target mirroring out of the box.
