Ray Vault Sync

Easy. Free. Seamless.
Lightweight, cross-device GitHub synchronization for your Obsidian vault with 3-way merge and zero silent data loss.

Features

• Gitless 3-Way Merge: Synchronizes your vault notes via GitHub's REST API without requiring a local Git CLI, Xcode, or heavy WebAssembly modules.
• Mobile & Desktop First: Works effortlessly on iOS, iPadOS, Android, macOS, Windows, and Linux.
• Zero Silent Data Loss: Strict conflict safety policy. If the same file is edited concurrently on two devices, both versions are safely preserved (.conflict-<timestamp>).
• Batched Atomic Commits: Groups changes into 500-item tree chunks and creates a single atomic Git commit per sync batch.
• Smart Rate-Limit Protection: Enforces 1-second request throttling and automated cooldown timers to strictly comply with GitHub API secondary rate-limit guidelines.
• Custom Exclude Patterns: Easily ignore unwanted folders or files (e.g. node_modules, templates/, private/) via comma-separated settings.
• Configurable Auto-Sync: Background auto-sync interval with safety debounce.
• Diagnostics & Health Check: Built-in diagnostics tool to verify repository connectivity, permissions, and detect pending diverged files.
• 100% Free & Open Source: Full control of your private notes backed by your own private GitHub repository.

Quick Start Guide

Step 1: Generate a GitHub Personal Access Token (PAT)

1. Go to GitHub Developer Settings > Personal Access Tokens (Fine-grained).
2. Click Generate new token.
3. Set Repository access to Only select repositories and select your private vault repository (e.g. ufebri/raylabs-vault).
4. Under Repository permissions, grant Read and Write access to Contents.
5. Copy the generated token (github_pat_...).

Step 2: Install & Configure the Plugin

1. Install Ray Vault Sync in Obsidian (Settings > Community Plugins).
2. Open Settings > Ray Vault Sync.
3. Enter your GitHub Personal Access Token.
4. Enter your GitHub Repository (owner/repo).
5. (Optional) Configure Excluded Folders / Patterns (default: node_modules, .git, ray-vault-sync).
6. (Optional) Enable Auto-Sync and set your preferred interval in minutes.

Step 3: Start Syncing!

• Click the Sync icon in Obsidian's left ribbon, or press Cmd+P / Ctrl+P and select Ray Vault Sync: Sync Now.

Handling Conflicts

If a file is edited independently on multiple devices without syncing in between, Ray Vault Sync will never guess a winner or overwrite your changes.

1. Your local version stays in place: MyNote.md.
2. The remote version is downloaded alongside it: MyNote.conflict-2026-08-25T14-30-00.md.
3. Open both notes side-by-side in Obsidian, merge your desired text, and delete the .conflict file.
4. Click Sync Now to finalize the resolution across all devices.

Privacy & Vault Access Disclosure

• Vault Enumeration (vault.getFiles): As a dedicated synchronization and backup tool, Ray Vault Sync enumerates files in your vault to calculate local SHA hashes and compare them against your remote GitHub repository tree.
• Data Privacy: Your notes and tokens are transmitted directly and exclusively to the official GitHub REST API (api.github.com) using your own configured repository and Personal Access Token. No data, telemetry, or analytics are sent to any third-party servers.
• Local Error Log: Recent errors are stored locally on your device (.obsidian/plugins/ray-vault-sync/error-log.json, tokens redacted). Nothing is uploaded automatically — use Copy in settings to share manually in a GitHub issue.
• Custom Exclusions: You can restrict which files or folders are accessed via the Excluded Folders / Patterns setting. Hidden files, internal directories (.obsidian, .git), and excluded patterns are strictly ignored.
