Version History ​

Track, label, and restore previous versions of your database schema.

WARNING

Version History is available on Pro and Team plans.

Overview ​

Every time you save your project, ERDHub captures a snapshot of your schema. The Version History panel gives you a timeline of all snapshots so you can review past states, compare changes, and restore previous versions when needed.

Accessing Version History ​

Open the History panel from within the editor. The panel displays a chronological list of all snapshots for the current project, with the most recent at the top.

Each snapshot shows:

  • Timestamp — when the snapshot was created
  • Creator — who made the change (useful in collaborative projects)
  • Label (if assigned) — a custom name for the snapshot

Labeling Snapshots ​

Add custom labels to important snapshots so you can find them quickly later.

Examples of useful labels:

  • "Before adding payments tables"
  • "v2 schema — approved by team"
  • "Pre-migration baseline"

Labels are especially valuable in long-running projects where the history grows large. Instead of scanning timestamps, you can look for your labeled milestones.

Restoring a Version ​

To restore your project to a previous snapshot:

  1. Open the History panel
  2. Find the snapshot you want to restore
  3. Click Restore
  4. Confirm in the dialog that appears

TIP

ERDHub automatically creates a safety snapshot of your current state before performing the restore. This means you can always get back to where you were — restoring is never destructive.

After restoring, your DSL editor, canvas, and schema panel all update to reflect the restored version.

Copying a Version ​

Instead of restoring (which replaces your current schema), you can copy any historical version into a brand-new project. This is useful when you want to:

  • Branch off from an earlier design without affecting the current project
  • Create an alternative schema based on a past snapshot
  • Archive a point-in-time version as a separate project

Auto-Save and History ​

ERDHub auto-saves your work as you edit. Each auto-save can create a history entry, but to avoid flooding your timeline with minor edits, auto-save entries are throttled with a minimum 5-minute gap between them.

Manual saves always create a history entry regardless of the throttle.

Retention ​

Snapshots are retained for 90 days. After 90 days, older snapshots are automatically removed.

TIP

If you have a critical milestone you want to preserve beyond the retention window, use Copy version to create a separate project from that snapshot.

For projects with many snapshots, the History panel uses cursor-based pagination. Scroll to the bottom of the list to load older entries automatically. Combined with snapshot labels, this makes it easy to navigate even months of history.

Best Practices ​

  • Label before major changes — Before a big refactor or migration, label your current snapshot so you can get back to it easily.
  • Use copy for experiments — When exploring a new schema direction, copy the current version to a new project instead of modifying in place.
  • Review before restoring — Check the timestamp and label carefully to make sure you are restoring the right version. The confirmation dialog is there for a reason.
