DotaSync

DotaSync is a lightweight desktop tool for syncing Dota 2 hotkeys, quickcasts, custom hero grids, audio/video settings, and launch options between local Steam accounts.

Why DotaSync?

If you play Dota 2 across multiple Steam accounts—such as a secondary account, a practice account, or on a friend's PC—setting up your preferences from scratch is tedious. You have to rebind dozens of hero hotkeys, quickcasts, item slots, camera settings, and custom hero grids.

Manually copying files inside Steam/userdata/<AccountID>/570/ is clunky and often gets wiped out by Steam Cloud if Steam synchronizes files at the wrong moment.

DotaSync solves this:

• Auto-detection: Automatically finds your Steam installation and lists your local accounts with avatars and display names.
• Granular sync: Choose exactly what to copy—launch flags, keybinds, hero grids, video/audio convars, or full config directories.
• Steam Cloud safe: Proactively checks if Steam or Dota 2 is running to prevent Steam Cloud from overwriting transferred files.
• Automatic snapshots: Takes a timestamped backup of the destination account before making any changes, with one-click restore.

Download

Pre-built binaries are available on the Releases page.

• Windows: Download DotaSync.exe — a single standalone executable. No installer, no setup wizard. Just save it anywhere and run it.
• Linux: Download DotaSync-linux-amd64.tar.gz, unpack it, and run ./DotaSync.

How to Use

1. Close Steam: Make sure Steam is closed before syncing so Steam Cloud doesn't overwrite your transferred configuration. (DotaSync will warn you if Steam processes are active).
2. Launch DotaSync: Your local accounts will appear automatically.
3. Select Accounts:
   • Source Account (Donor): The account whose settings you want to copy.
   • Target Account (Recipient): The account that should receive the settings.
4. Choose Transfer Scope:
   • Launch Options: Copies launch flags from localconfig.vdf (e.g. -novid -high -fullscreen).
   • Keybinds & Controls: Copies hero layouts, quickcasts, and ability keys (dotakeys_personal.lst, user_keys_*.vcfg, etc.).
   • Custom Hero Grids & Layouts: Copies custom category tabs and hero arrangements (hero_grid_config.json).
   • Audio & Video Settings: Copies machine convars and display settings (machine_convars.vcfg, video.txt).
   • All Config Files: Full clone of the 570/remote/cfg/ directory.
5. Click Sync: A backup snapshot of the target account is archived automatically before files are applied.
6. Start Steam: Open Steam, launch Dota 2, and all your settings are ready.

Backups & Restoring

Every sync operation saves a timestamped snapshot of the target account inside the backups/ directory. Click Backups in the top navigation bar to view previous snapshots or restore a past configuration with one click.
