# Version Control
> Store prompt versions as you iterate
export const AskAlyx = ({children}) => {
const gradientId = `askAlyxGradient-${Math.random().toString(36).slice(2)}`;
return ;
};
Prompt Hub allows you to create and store multiple versions of the same prompt object.
**Ask Alyx** to save a new version of your prompt for you.
# Why Have Version Control on Prompts?
Prompt versioning lets you experiment, iterate, and safely improve your prompts without losing past work. As you refine a prompt's structure, parameters, or connected tools, version control ensures that every change is tracked and reproducible.
With version control, you can:
* **Compare and revert easily:** If a new edit performs worse, you can instantly roll back to a previous version.
* **Collaborate safely:** Multiple team members can test variations of the same prompt without overwriting each other's work.
* **Maintain traceability:** Each version can include notes describing what changed and why—helpful for debugging and auditing.
* **Measure improvements:** Track performance across prompt iterations to identify which modifications lead to better model responses.
In short, version control brings the same rigor and reliability of code versioning to your prompt engineering workflow—so you can iterate faster, with confidence.
