n8n uses Git-based source control to support environments. Linking your n8n instances to a Git repository lets you create multiple n8n environments, backed by Git branches.

In this section:

• Understand:
  • Environments in n8n: The purpose of environments, and how they work in n8n.
  • Git and n8n: How n8n uses Git.
  • Branch patterns: The possible relationships between n8n instances and Git branches.
• Set up source control for environments: How to connect your n8n instance to Git.
• Using:
  • Push and pull: Send work to Git, and fetch work from Git to your instance.
  • Copy work between environments: How to copy work between different n8n instances.
  • Manage variables: Manage variable values using the n8n API and source control.
• Tutorial: Create environments with source control: An end-to-end tutorial, setting up environments using n8n's recommended configurations.
