Plazer

A messenger is a program that stays open all day, next to a game, an editor, a browser and whatever you are working on. That is why the Plazer desktop app is native: written in Rust on Slint, with software rendering and no browser underneath. It runs on Windows, macOS and Linux, on the same account as the phone and the browser.

The choice of stack came after prototypes in three technologies, compared on the same computer for idle memory, memory under load and package size. Slint came out lightest on every one of those measures, so that is what the app was built on.

The Rust encryption core is an ordinary dependency for the client, with no layer translating between languages. Encrypting chats on the desktop runs the same code as the browser version, not a copy written a second time.

An encrypted client should run the same code for everyone, not code fetched again on every launch. The app is installed once, from a single file, with no extra runtimes or libraries, and it downloads new versions by itself, so nobody has to look for an installer on the website.

The desktop has every conversation, servers with channels, roles and a forum, voice channels with screen sharing, and appearance and accessibility settings. A desktop widget shows your chats at a glance, and system notifications on Windows, macOS and Linux never contain the message content.

When the old device is gone, you sign in with your password and recovery key and restore the history from an encrypted backup.
