Alternatives to AeroFTP
Open-source, cross-platform FTP/SFTP/S3/WebDAV client built with Rust and Tauri
AeroFTP ranks #2 of 11 in FTP clients, with an Alt Score of 90. It is licensed under GPL-3.0, free from Free and available on Windows, macOS and Linux. 9 of 9 checklist rows are verified against a public source.
AeroFTP is a modern open-source desktop file transfer client for Windows, macOS, and Linux, built on Rust/Tauri, supporting FTP, FTPS, SFTP, WebDAV, S3-compatible storage, Azure Blob, and other cloud providers. It positions itself explicitly as a lightweight, actively developed open-source alternative to FileZilla, WinSCP, and Cyberduck.
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.
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.
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.
