ffsend is an open-source command-line tool inspired by Mozilla's Firefox Send, enabling users to securely upload and share files or folders with end-to-end encryption.

It supports features like password protection, customizable expiration times, download limits, and progress tracking. Files are uploaded to a relay server (default: relay.ffsend.com), generating a unique shareable URL.

Key benefits include no account required, client-side encryption (using 256-bit AES-GCM), and bandwidth-efficient transfers. Users can upload single files, multiple files, or directories (with --archive). Recipients download via browser or CLI without needing ffsend.

Developed in Rust for performance and safety, it's cross-platform (Linux, macOS, Windows). Note: Firefox Send service ended in 2020; ffsend uses community-hosted relays.

Depends on relay server availability (e.g., send.vis.ee); large files may hit limits (~5GB default); end-to-end encryption but trust relay for availability.
No built-in resume for interrupted uploads.

Via Cargo: cargo install ffsend-cli
Binaries: GitHub releases; Arch: AUR ffsend; Homebrew on macOS.

ffsend upload -p mypass file.zip → Generates URL like https://send.vis.ee/abc123/#mypa55

Created by Tim Schumacher (tmsch) in 2019 as Firefox Send CLI. Firefox Send discontinued 2020; ffsend pivoted to own relays like relay.ffsend.com. Actively maintained on GitHub (ffsend/ffsend), latest v1.3.x (2023). Written in Rust.
