CI status



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.

It is recommended to download the app either from an app store or from a package manager because the app does not have an auto-update.

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).

Portable Mode

(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.

How It Works

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.

Getting Started

To compile LocalSend from the source code, follow these steps:

  1. Install Flutter directly or using fvm (see version required)
  2. Clone the LocalSend repository
  3. Run cd app to enter the app directory
  4. Run flutter pub get to download dependencies
  5. Run flutter run to start the app

LocalSend currently requires an older Flutter version (specified in .fvm/fvm_config.json)
and thus build issues may be caused by a mismatch between the required and the (system-wide) installed Flutter version.
To make development more consistent, LocalSend uses fvm to manage the project Flutter version.
After installing fvm, run fvm flutter instead of flutter.


We welcome contributions from anyone interested in helping improve LocalSend. If you’d like to contribute, there are a few ways to get involved:

    • Add new languages: Create a new file; see also: locale codes.
  3. Optional: Re-run this app
    1. Run cd app to enter the app directory.
    2. Make sure you have run this app once.
    3. Update translations via flutter pub run slang
