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.

Compatibility
Platform Minimum Version Note Android 5.0 - iOS 12.0 - macOS 11 Big Sur Use OpenCore Legacy Patcher 2.0.2 (See #1005) Windows 10 The last version to support Windows 7 is v1.15.4. There might be backports of newer versions for Windows 7 in the future. Linux N.A. -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 AllowAlso 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). See troubleshooting for more information.
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.
Start hidden
(Updated in v1.15.0)
To start the app hidden (only in tray), use the --hidden
flag (example: localsend_app.exe --hidden
).
On v1.14.0 and earlier, the app starts hidden if autostart
flag is set, and the hidden setting is enabled.
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:
LocalSend
repositorycd app
to enter the app directoryflutter pub get
to download dependenciesflutter run
to start the appNote
LocalSend currently requires an older Flutter version (specified in .fvmrc) 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:
You can help translate LocalSend into other languages. We use the Weblate platform to manage translations.
Alternatively, you can also contribute by forking this repository and adding translations manually.
The translations are located in the app/assets/i18n directory. Edit the _missing_translations_<locale>.json
or strings_<locale>.i18n.json
file to add or update translations.
Take note: Fields decorated with @
are not meant to be translated; they are not used in the app in any way, being merely informative text about the file or to give context to the translator.
