Everything you need to sync your dev environment

Tether combines automatic syncing, encryption, and package management into one seamless tool.

End-to-End Encrypted

AES-256-GCM encryption with passphrase-protected keys. Your dotfiles are encrypted before syncing to Git.

Automatic Sync

Set it once, forget about it. Background daemon automatically syncs changes across all your machines in real-time.

Team Sync

Share team configurations with automatic symlink management. Configs seamlessly sync to tool locations like ~/.claude/ for teams.

Package Managers

Syncs Homebrew (formulae, casks, taps), npm, and pnpm global packages. Never manually install again.

Secret Detection

Automatically scans for API keys, tokens, and credentials before syncing. Prevents accidental leaks.

Built in Rust

Single binary, no dependencies. Fast, efficient, and reliable. <10MB size, <20MB memory usage.
