​
Version History

Voiceblox keeps up to 50 snapshots per agent. Each significant change (node addition, deletion, parameter edit, edge change) creates a new snapshot.

Undo and redo are also available in the top toolbar.

​
Version snapshots

When the AI generator applies operations to your flow, it creates a named snapshot with the description of the change (e.g., “Added billing branch”). You can view and restore named snapshots from the Version History panel in the toolbar.

​
Persistence

Version snapshots are saved to the local SQLite database automatically — they persist across page reloads and browser restarts. There is no need to export your flow to preserve version history.
  • Up to 50 snapshots stored per agent
  • Content-hash deduplication — identical consecutive states do not create duplicate entries
  • Snapshots are tied to the current agent; switching agents loads that agent’s own version history

​
Exporting

To share or back up a flow externally, you can still export it as JSON at any time:
  1. Click Export in the toolbar
  2. Download the JSON file
  3. Re-import it later via Import to restore the flow
See Export as JSON for the full format.
