# Save, compare, and restore browser-local parser versions

> Use Local Versions for up to 30 local parser checkpoints with source and mapping comparison.

# Save, compare, and restore local versions

The **Local Versions** control opens a browser-local workspace for saving the current parser state.

![Current Local Versions workspace](https://mintcdn.com/xdr-parser/eZQo8zkyp__tw0U0/images/current-07-local-versions.png?fit=max\&auto=format\&n=eZQo8zkyp__tw0U0\&q=85\&s=4b96326e1ae327eff05870fe8dc68cde)

## Save a checkpoint

1. Enter or analyze some sample logs.
2. Open **Local Versions**.
3. Enter a meaningful **Version name**, such as Before normalization.
4. Select **Save Version**.
5. Make a deliberate change to mappings or sample groups, then save another named version.

## Compare and restore

Under **Compare Versions**, choose Version A and Version B (or Current working copy) to review differences in source logs, parser settings, and field mappings. Use a saved version's **Restore** action when you need to roll back your browser workspace.

## Storage boundaries

* Up to **30 saved versions**, scoped to the current browser profile and website origin.
* Versions are **not stored on the Parser Studio server** and do not sync between devices.
* The saved data can include raw security logs and is **not encrypted by Parser Studio**.
* Clearing site data, private browser cleanup, or changing profiles/origins may make versions unavailable.

Saving a local version is not a native parser test, repository commit, or deployment operation.
