Prompt Version Control

LangWatch provides a robust version control system for managing your prompts. Each prompt can have multiple versions, allowing you to track changes, experiment with different approaches, and rollback when needed.

​
Version Management

Every prompt in LangWatch automatically maintains a version history. When you create a new prompt, it starts with version 1, and each subsequent change creates a new version with an incremented number.

​
Managing Versions

Use the LangWatch UI to manage prompt versions:
  1. Navigate to the Prompt Management section
  2. Select a prompt
  3. Click on the version history icon at the bottom of the prompt editor
  4. Use the version selector to switch between versions
  5. Create new versions by making changes and saving

​
Version History

LangWatch provides a clear view of how your prompts have evolved over time:

  • Version Selection: Switch between different versions to view their content

​
Version Information

Each prompt version includes metadata such as version number, commit message, author, and creation timestamp. For detailed information about the version structure and data model, see the Data Model page.

​
Rollbacks

You can easily rollback to previous versions:
  1. Navigate to the prompt’s version history
  2. Select the version you want to restore
  3. Create a new version based on the selected version
  4. The new version will include the restored content

​
Team Collaboration

All prompt versions are shared across your project team. For organization-scoped prompts, versions are also shared across all projects in the organization.
