Argo CD Pull Request Automation.
Lemuria enables teams to preview, approve, and sync Argo CD applications through GitHub PR or GitLab MR comments. It acts as a bridge between your VCS provider and Argo CD, providing a GitOps-native workflow where infrastructure changes are reviewed as manifest diffs before deployment.

- PR/MR Comment Interface — Interact via
lemuria plan,lemuria sync,lemuria unlock,lemuria rollback - Auto-diff — Automatically generate and post manifest diffs when relevant files change
