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.

Read more about distribution channels.

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.

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.

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.

1. Install Flutter directly or using fvm (see version required)
2. Clone the LocalSend repository
3. Run cd app to enter the app directory
