Vault Time Machine for Obsidian

Scrub your whole vault back through time. Drag a slider to see every note that changed since then, read the diff, and restore one note or all of them. No git, no sync service, no setup. Works on desktop and mobile.

What it does

• Time slider for the whole vault. The strip above the slider shows when you were editing, so you can jump to a busy day. ◀ ▶ step to the previous or next change anywhere in the vault; Now snaps back.
• See what changed since. Pick a moment and the list shows every note that was added (A), edited (M) or deleted (D) since, with a diff against the note as it is now. Changed words are highlighted inside a rewritten line.
• Restore safely. Restore one note, restore it as a copy next to the original, bring back a deleted note, or restore everything that changed since that moment. The current text is saved first, so a restore can always be undone. Notes created after the moment are never deleted.
• Automatic. A note's new state is saved after you stop editing it for 20 seconds. Notes edited while Obsidian was closed are picked up on the next start. Renames and deletions are tracked.
• Stays small. Identical content is stored once. Old history thins out like Starnote's: every version for a day, hourly for a week, daily for three months, weekly after that. Optionally drop history older than N days. The newest version of every note is always kept.
• Private and local. History lives in .obsidian/plugins/vault-time-machine/history inside your vault and never leaves your device.

Commands: Open Time Machine, Show history of this note, Save a snapshot of every note now, Thin out old history now.

Install

BRAT (installs and keeps it updated)

1. Install BRAT from Settings → Community plugins → Browse, and enable it.

Manual

Copy main.js, manifest.json and styles.css from the latest release into <vault>/.obsidian/plugins/vault-time-machine/, then enable the plugin. To build it yourself:

npm install
npm run build

Notes and limits

• Only Markdown notes are tracked (not attachments). Notes larger than 2 MB are skipped by default, and folders can be excluded in the settings.
• History starts when you install the plugin; existing notes begin at their last-modified time.
• This is a safety net, not a backup. Keep a real backup of your vault too.

Development

npm run dev     # rebuild main.js on change
npm run check   # type-check
npm test        # unit tests (node --test): diff engine and history store

The engine (src/history.ts, src/diff.ts) has no Obsidian dependency and is covered by 29 tests, including a randomised diff round-trip test and a concurrency test for the store. Tested in Obsidian 1.14.4 (Flatpak, Linux).

Disclosures

• Network use: none.
• Files outside your vault: none. History is stored inside your vault at .obsidian/plugins/vault-time-machine/history.
• No account, payment, ads, telemetry or self-updating.
