An open-source, ultra-lightweight web application and CLI daemon designed to track and instantly rewind a corrupted or modified SQLite database file back to any previous state (e.g. 3 minutes ago) during local development — just like scrubbing a video.

• ⚡ Zero Dependencies: Built with pure PHP 8+ and Vanilla JS. Requires no heavy frameworks or npm packages.
• 🌐 Full i18n / Multi-Language: Translation files are completely decoupled in lang/. Switch languages dynamically from the UI (e.g., 🇹🇷 Turkish, 🇬🇧 English). Easily contribute by adding or updating lang/xx.json files.
• 💾 SQLite WAL Mode Aware: Seamlessly backs up and restores .sqlite-wal and .sqlite-shm files for databases running PRAGMA journal_mode=WAL;.
• 🔍 Visual Data & Table Diff Viewer: Compare row counts and table changes (+3 rows in live) between any historic snapshot and your current live database before restoring.
• 📌 Snapshot Pinning & Tagging: Pin important snapshots with one click to protect them from auto-cleanup.
• 📥 One-Click Snapshot Export: Download any historic database state directly as a .sqlite file.
• ⌨️ Keyboard Navigation Shortcuts: Navigate through the timeline smoothly using Left Arrow (⬅️) and Right Arrow (➡️) keys.
• 🔄 Automatic Instant Snapshots (Watcher Daemon): Background CLI script (watcher.php) listens for modifications in database.sqlite and automatically creates timestamped snapshots (backups/1715000000_database.sqlite).
• 🧹 Automatic Cleanup: Maintains up to 50 backups, purging older unpinned snapshots to prevent disk clutter.

Create a JSON file inside lang/ matching the ISO code (e.g., lang/es.json, lang/de.json):

{
  "code": "es",
  "name": "Español",
  "flag": "🇪🇸",
  "cli": { ... },
  "api": { ... },
  "ui":  { ... }
}

Open any file in lang/*.json and edit strings. Changes reflect immediately on the Web UI and CLI without restarting the server.

To specify custom language or database file:

php watcher.php database.sqlite en

Open your browser and navigate to: http://127.0.0.1:8000

1. Open the web interface.
2. Click "✍️ Add Test Data (DB Write)".
3. Observe terminal output from watcher.php: [+] Created snapshot: 1715000000_database.sqlite
4. Drag the timeline slider or use ⬅️ / ➡️ arrow keys.
5. Click "🔍 Compare Diff" to inspect table row changes.
6. Click "⚡ Restore To This State" to rewind your database!
