OpenDrop is a command-line tool that implements the AirDrop protocol to enable file sharing between devices over Wi-Fi.
OpenDrop solves the problem of cross-platform file sharing by reverse-engineering and implementing Apple's AirDrop protocol, making it possible for non-Apple devices to participate in AirDrop transfers. The tool works by establishing direct Wi-Fi connections and speaking the AirDrop protocol natively, allowing it to send files and links to iOS and macOS devices, and to receive files from them. A key capability is support for contacts-only mode devices through extracted AirDrop credentials obtained via a companion keychain extractor tool.
Adoption requires understanding that OpenDrop is experimental software resulting from reverse engineering, and therefore may not support all AirDrop features or remain compatible with future AirDrop versions. The tool runs only on macOS or Linux systems with Apple Wireless Direct Link support, either native on macOS or via an open re-implementation on Linux. It requires Python and libarchive, with the latter needing manual installation on macOS. OpenDrop suits developers and users who need to send files from Linux or macOS to Apple devices, or who want to receive AirDrop transfers on non-standard platforms. The README does not compare it to alternative implementations.
Development shows consistent engagement with the codebase through regular commits addressing both new features and maintenance. The project maintains active responsiveness to issues and pull requests, indicating ongoing attention to user-reported problems and community contributions. Documentation is kept current alongside code changes, reflecting a commitment to keeping usage guidance aligned with the tool's capabilities.
