ClearSkies is an open-source file synchronization program inspired by BitTorrent Sync, allowing direct peer-to-peer sharing between computers without a monthly fee. It defines an open, auditable sync protocol with encrypted connections, read-only sharing, and subtree/shallow copy support, with a Ruby proof-of-concept implementation.

Use cases

• sync files between my computers without paying for dropbox
• self-hosted alternative to bittorrent sync
• share folders directly between peers without a cloud server
• open source file sync with an auditable protocol
• read-only folder sharing between machines
• encrypted peer-to-peer file synchronization

When to choose

• you want a free, self-hosted, serverless file sync between your own devices
• you need an open, auditable sync protocol instead of a proprietary one
• you want to experiment with or build on an open p2p sync protocol

When to avoid

• you need a maintained, production-ready sync tool - development stopped around 2014
• you want polished clients for Windows, Android, or iOS
• you need anonymity or protection against active man-in-the-middle attacks during share setup
