Local WiFi File Transfer FTP HTTP Server App Android
DropLine Server – Wi-Fi FTP & HTTP File Server (Flutter Android App)
DropLine Server turns any Android phone into a fast, local Wi-Fi file server. Share files between your phone, laptop and other devices using a browser (HTTP) or an FTP client, with no USB cables and no external cloud services.
Key Features
- Wi-Fi FTP server – Full FTP server running directly on the device so you can browse, upload and download files from tools like FileZilla, WinSCP and other FTP clients.
- HTTP file server – Simple web UI that lets you manage files from any modern browser on the same network (Chrome, Edge, Firefox, Safari, etc.).
- Configurable ports and credentials – Change FTP and HTTP ports, username and password, enable or disable anonymous access and read-only mode from the Settings screen.
- Foreground service – Reliable background operation using an Android foreground service with a persistent notification while the server is running.
- Connected clients and transfer stats – See currently connected clients and basic transfer statistics (upload and download totals for FTP and HTTP).
- Onboarding and in-app tutorial – Built-in guidance that shows users how to connect from Windows, macOS and other devices on the same Wi-Fi network.
- Local-only and privacy-friendly – All traffic stays inside the local network; there is no external backend, account system or cloud dependency.
