Explore Linksy, an open-source local connectivity tool enabling direct device communication without cloud storage or accounts.
It supports secure file transfers, clipboard sync, remote terminal access, and webcam integration using QUIC and TLS 1.3.
The application allows computers, mobile phones and tablets to communicate directly with each other when they are on the same local network, without the need for an internet connection, accounts or cloud storage.
What Linksy can do
At its core are the sending of files and folders, with the ability to resume an interrupted transfer, and the synchronization of text copied by the user to the clipboard. Automatic clipboard synchronization is supported in KDE Plasma and wlroots-based environments, while there are limitations in GNOME.
Beyond files, Linksy offers advanced features:

Security and remote connection
To protect data, the app uses strong encryption and mutual authentication. Connecting devices is easy using a QR code or a six-digit verification code, while actions such as screen sharing and remote control always require user approval.
Although the application works primarily locally, it supports online reconnection for up to a week for devices that have previously reconnected. In these cases, a relay server forwards only encrypted data without storing its content.
Availability
The official website lists version 0.8.7. There are ready-made installation packages for Debian, Ubuntu, Fedora and openSUSE, as well as an installation option via Flatpak, while future availability on Flathub and AUR is planned.
