## Where AeroFTP stands out

- **Speed limits & scheduling** — 4 of 10 apps with a verified answer have this
- **Open source** — 5 of 11 apps with a verified answer have this

## Overview

- **Who it's for**: AeroFTP targets developers, sysadmins, and power users who need a single desktop client to move files between local machines, FTP/SFTP/WebDAV/S3 servers, and 20+ cloud storage providers, including those who script transfers or drive file operations through AI coding assistants.
- **What you get**: A cross-platform desktop app (Windows, macOS, Linux) built with Rust and Tauri that bundles a dual-pane file browser, a bidirectional sync engine with mirror/two-way/backup modes and bandwidth throttling and scheduling, an encrypted vault-backed file encryption module (AeroVault), a Monaco-based remote code editor, an SSH terminal, and a 90-command CLI with an MCP server mode for AI agents. It is fully open source under GPL-3.0 with no paid tier.
- **How it works**: Users add server or cloud-provider profiles whose credentials are stored in an AES-256-GCM encrypted local vault; the app then connects natively over FTP, FTPS, SFTP, WebDAV, S3, Azure Blob, or OpenStack Swift, or through dedicated provider integrations, to browse, transfer, sync, or diff files. The same profile-based connections are exposed to automation through the CLI and to AI assistants through an MCP server, so credentials never leave the local Rust backend.
