fsend review
A free, open-source choice for private browser and command-line transfers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
fsend is a free, open-source file-transfer product for sending files and folders directly between devices. Its web application uses WebRTC for peer-to-peer transfers, with end-to-end encrypted data channels and one-time share codes. Users can select files or folders with drag and drop, while the command-line tool supports Linux, macOS, Windows, and other supported environments. It is aimed at people who want direct transfers without storing file data on fsend’s servers, particularly self-hosting users and command-line workflows.
The browser experience centers on a focused transfer model: choose files or folders, create a one-time share code, and keep both browser tabs open while the transfer runs. Password protection adds an access control option, and resumable transfers are available in supported Chromium-based browsers. The command-line tool broadens the product beyond ordinary browser sharing, supporting multiple files, folders, stdin streams, and text. This combination makes fsend more suitable for technical workflows than for users looking for a broad collaboration or file-management platform.
Self-hosting with Docker Compose gives teams a deployment option when they want to operate the service themselves. The product runs across web, Windows, macOS, and Linux, but the browser workflow has practical constraints: both participants must remain connected through open tabs, and resumability depends on browser support. There is also no mobile coverage described. Choose fsend for encrypted peer-to-peer transfers, command-line sending and receiving, or a self-hosted setup. Choose another service if mobile clients, integrated APIs, or a more managed sharing experience are central requirements.
