LocalSend vs File.io

LocalSend lets you instantly transfer files and folders between devices on the same Wi‑Fi or LAN without internet. It works on Windows, macOS, and Linux, offering a simple, ad‑free experience for home users and small teams. The open‑source desktop app runs in the background, detects nearby devices, and encrypts transfers end‑to‑end. No accounts or cloud storage are required, keeping your data private and under your control.

File.io is a streamlined file-sharing platform designed for privacy, convenience, and automation. Users can quickly upload documents, media, or archives and share the generated links across various communication channels. The service stands out for its ephemeral storage model, ensuring that files are automatically deleted after being downloaded once or after a specific time period. Additionally, it offers a robust REST API for seamless integration into custom applications and workflows.
