LocalSend
Apache-2.0LocalSend is an open-source alternative to Apple AirDrop that transfers files and clipboard text securely across local networks without cloud accounts.

Overview
LocalSend is an open-source file sharing utility that transfers photos, documents, and text messages directly between nearby devices over a local area network. Unlike cloud storage platforms or vendor-locked utilities, it completes transfers entirely offline without external relays, user accounts, or internet access.
Why LocalSend instead of Apple AirDrop
Apple AirDrop delivers low-friction sharing across Macs, iPhones, and iPads through proprietary Bluetooth and Wi-Fi Direct protocols. However, that capability stops at Apple's ecosystem wall. Introducing a Windows desktop, Linux workstation, or Android phone breaks the transfer path, forcing users toward cloud drives, self-addressed emails, or USB cables. LocalSend solves this cross-platform gap by implementing an identical protocol across Windows, macOS, Linux, Android, and iOS, letting any local device find and exchange files with another.
From a privacy and control perspective, LocalSend removes external intermediaries. While AirDrop ties discovery to Apple IDs and contact hashes, LocalSend functions without accounts, telemetry, or central tracking servers. Devices negotiate transfers over encrypted local HTTPS connections using ephemeral TLS certificates generated on the fly. Payloads move directly across your local Wi-Fi at local network speeds, never leaving your premises. The trade-off is operational: both devices must run the application and connect to the same local subnet.
What it does well
- Cross-platform support across Windows, macOS, Linux, iOS, Android, and Fire OS with a unified interface.
- Localized security model that generates ephemeral TLS certificates on device to encrypt transfers across the local network.
- Uncompressed file transfers that preserve original media quality, metadata, and directory trees.
- Quick text and clipboard transmission for sharing links, notes, or passwords without messaging apps.
- A built-in web share mode that lets nearby devices download files through any browser using a local link or QR code.
- Desktop system tray integration and auto-accept options for background reception.
Limitations
- Router subnet constraints: Transfers require a shared local network and fail on public or corporate Wi-Fi where access point isolation blocks client-to-client traffic.
