LocalSend is a free, open-source app that allows you to securely share files and messages with nearby devices over your local network without needing an internet connection.
LocalSend is a cross-platform app that enables secure communication between devices using a REST API and HTTPS encryption.
Unlike other messaging apps that rely on external servers, LocalSend doesn’t require an internet connection or third-party servers, making it a fast and reliable solution for local communication.
In most cases, LocalSend should work out of the box.
However, if you are having trouble sending or receiving files, you may need to configure your firewall to allow LocalSend to communicate over your local network.
| Traffic Type | Protocol | Port | Action |
|---|---|---|---|
| Incoming | TCP, UDP | 53317 | Allow |
| Outgoing | TCP, UDP | Any | Allow |
Also make sure to disable AP isolation on your router. It should be usually disabled by default but some routers may have it enabled (especially guest networks).
(Introduced in v1.13.0)
Create a file named settings.json located in the same directory as the executable. This file can be empty.
The app will use this file to store settings instead of the default location.
LocalSend uses a secure communication protocol that allows devices to communicate with each other using a REST API.
All data is sent securely over HTTPS, and the TLS/SSL certificate is generated on the fly on each device, ensuring maximum security.
For more information on the LocalSend Protocol, see the documentation.
To compile LocalSend from the source code, follow these steps:
cd app to enter the app directory.flutter pub get to download dependencies.flutter run to start the app.The issue may be caused by a mismatch between the required Flutter version and the installed Flutter version.
LocalSend uses fvm to manage the project Flutter version (specified in .fvm/fvm_config.json). After you install it, run fvm flutter instead of flutter.
