Version History

Every generation, refinement, and edit creates a version snapshot. Compare changes and rollback to any point with one click.

How Versions Work

Every time your app's code changes, GenMB automatically creates a version snapshot. This includes initial generation, chat refinements, visual edits, GenMB Code sessions, and plugin changes. Each version is a complete copy of your project at that point in time.

Automatic version creation

You never need to manually save a version. GenMB creates snapshots automatically after every code change, so you always have a complete history of your project's evolution.
  • ●Initial generation creates version 1 of your app.
  • ●Each chat refinement creates a new version with the updated code.
  • ●Visual Editor changes create a version after each edit session.
  • ●GenMB Code sessions create a version when the AI reports its changes are done.
  • ●Plugin configuration changes that trigger code updates also create new versions.

Viewing Versions

Access your version history from the Versions panel in the app editor sidebar. Each version shows when it was created and what triggered it, making it easy to find the exact point you want to return to.

1

Open the Versions panel

Click the clock icon in the app editor sidebar to open the Versions panel.
2

Browse the timeline

Versions are listed in reverse chronological order — newest first. Each entry shows a timestamp and the trigger type (generation, refinement, visual edit, etc.).
3

Preview a version

Click any version to preview it and see the code at that point in time. The preview panel shows the app as it looked at that version.
4

Compare changes

Compare versions side-by-side to see exactly what changed between them. The diff view highlights additions, deletions, and modifications.

Rolling Back

Restore any previous version with one click. Rolling back does not delete the versions that came after — it creates a new version that contains the old code, keeping your entire timeline intact.

1

Select a version

Click any version in the history to select it and preview its contents.
2

Click the rollback button

Click the rollback button to restore this version. A new version is created with the old code — history is never rewritten.
3

Continue working

After rolling back, you can continue refining from the restored code as normal. The version timeline stays intact with the rollback as the latest entry.

You can even rollback a rollback — since every restore creates a new version, nothing is ever permanently lost.

Safe experimentation

Experiment boldly with your app. If a refinement goes wrong, rollback takes one click and you never lose your previous work. Version history makes every change reversible.

Version Limits

Versions are stored in Firestore and are available for the lifetime of your app. There are no version count limits on any plan — you can accumulate as many versions as you need.

  • ●All plans (Free, Pro, Business) have unlimited version history.
  • ●Versions are stored efficiently — only the files that changed are duplicated, not the entire project.
  • ●Deleting an app removes all associated versions permanently.
  • ●Version data is stored securely and is only accessible to the app owner and collaborators.

Tips

Use version history to experiment freely and recover from mistakes.

Note your checkpoints

Before making a large change (e.g., redesigning the layout), note the current version number so you can easily find it later if you need to rollback.

Learn from the AI

Use version history as a learning tool — compare versions to see how the AI modified your code. This helps you understand patterns and techniques.

Iterate with confidence

If you are iterating quickly, check the version list periodically to make sure you have a known-good checkpoint. This makes it easy to backtrack if needed.

FAQs

Is there a limit on how many versions I can have?▾
No. All plans have unlimited version history. Every change creates a snapshot and they are kept for the lifetime of the app.
Does rolling back delete newer versions?▾
No. Rolling back creates a new version that restores the old code. All existing versions remain in the history. You can always go forward again to any version.
Can I compare two versions side by side?▾
Yes. Select a version to preview it and compare the code differences with the current version. The diff view highlights exactly what changed.
What triggers a new version?▾
New versions are created by initial generation, chat refinements, visual editor changes, GenMB Code sessions, and plugin updates that modify code. Saving without changes does not create a version.
