Features

Cross-OS & Steam Deck Paths

Stores portable path rules (<game_dir>, <win_appdata>, <win_locallow>, <win_documents>) and translates them across Windows, macOS, and Linux Wine/Proton compatdata prefixes.

Engine Fingerprinting

Automatically detects save directories for Ren'Py, RPG Maker (MV, MZ, VX Ace, VX, XP), Kirikiri / KAG (.xp3), and Unity games.

Content-Addressable Vault

Packs save directories into deterministic .tar.zst archives hashed with BLAKE3. Keeps local safety snapshots before any restore or sync overwrite.

Lineage Conflict Detection

Tracks parent snapshot IDs and BLAKE3 tree hashes for safe fast-forward push/pull, or side-by-side conflict resolution when two devices diverge.

Unified Storage Backends

Powered by Apache OpenDAL. Sync via S3-compatible storage (Cloudflare R2, AWS S3, MinIO, Backblaze B2), WebDAV (Nextcloud, ownCloud, Synology), or local/network folders.

VNDB Metadata & Launcher

Fetches game titles, Japanese titles, cover art, and descriptions from VNDB API v2. Launches games with pre-flight save pull, tracks playtime, and snapshots on exit.

Technical Specifications

Supported Engines	Ren'Py, RPG Maker (MV / MZ / VX Ace / VX / XP), Kirikiri / KAG, Unity, and custom path rules
Sync Storage Backends	S3 / R2 / B2 / MinIO, WebDAV (Nextcloud / ownCloud), Local & Shared Network Folders
Archive & Integrity	Zstandard (`.tar.zst`) compression with deterministic BLAKE3 content hashing
Stack	Tauri v2 (Rust backend, SQLite local catalog) + Vue 3 / Nuxt UI v4 frontend
License	GPL-3.0 Open Source

Development Status: VNSync is under active development. Automatic local backup snapshots are created before any sync overwrite, but keeping independent backups of critical saves is always recommended.
