SyncCrate compares game folders between players and transfers only what's different. Peer-to-peer at LAN speed. Works on local networks and virtual LANs like Tailscale.
Windows · macOS · Linux
Playing modded games with friends means shared zip files, outdated mods, and broken sessions.
SyncCrate scans both sides, shows differences, and transfers only what changed.
Supported Games
Add games to your library. Each game gets its own dashboard, content browser, profiles, and backups.
Features
Everything you need to keep your game mods in sync with friends.
Files transfer directly between computers at 100-900 MB/s. Nothing leaves your network. No cloud, no uploads.
SHA-256 hash comparison. Only transfers what's different — identical files are skipped automatically.
Keep yours, use theirs, or keep both. Every conflict is resolved on your terms before any files move.
Organize mods with built-in tags. Bulk-tag, filter, and search across your entire collection.
Snapshot your mod setup, export as a .synccrate-profile file, share on Discord. Friends drag it in and they're set.
Full snapshot of your game content. Safety backup created automatically before every restore.
No servers, no accounts, no tracking, no data collection. Files stay between you and your friends.
zstd compression reduces bandwidth 50-80%. Negotiated per-peer automatically. Already-compressed files are skipped.
Back up before every sync or on a schedule. Old auto-backups are pruned to save disk space. Never lose your mods.
Interrupted syncs pick up where they left off. No more restarting large transfers from scratch.
Automatically finds your game folders. Detects installed DLC, packs, and checks mod compatibility.
Flags potentially risky files (.ts4script, .lua, .jar, .dll) per game before syncing so you can review them.
