LocalSend: Cross-Platform Open-Source File Sharing over Local Networks

Repositorylocalsend/localsendTool

LocalSend is an open-source alternative to Apple AirDrop, enabling secure file and message sharing across nearby devices over a local network without requiring an internet connection or external servers.

Key points

  1. Cross-platform support across Windows, macOS, Linux, Android, iOS, and Fire OS, alongside a CLI.
  2. Entirely local transfers operated through local networks without routing data through third-party servers or the internet.
  3. Secured communication layer powered by a REST API and HTTPS encryption.
  4. High community adoption with over 90,000 GitHub stars and continuous localisation via Weblate.

Why it matters

Proprietary peer-to-peer file transfer protocols such as AirDrop or Quick Share usually lock users into specific ecosystems. LocalSend breaks down cross-OS barriers for teams and individuals while upholding data privacy, ensuring files never traverse external cloud infrastructure.

Analysis

LocalSend tackles the challenge of sending files across mixed operating system fleets (such as between Android, macOS, Linux, and Windows). The codebase is implemented in Dart using Flutter, delivering a consistent interface across desktop and mobile platforms. Transfers rely on local REST interfaces secured with HTTPS. With over 90,000 GitHub stars, 5,000 forks, widespread availability across official package managers, and automated CI pipelines, the project displays a high level of operational maturity.
