Firefox extension · v1.0

Your web activity, live on Discord

Syncr shows what you are watching, listening to, and reading, right on your Discord profile. Free, open, and it never leaves your machine.

No Discord login No paywall, ever Zero telemetry
Why Syncr

Rich presence, done properly

Everything the paid tools gate behind a subscription, given away for free and kept on your own machine.

Real-time updates

Switch a tab and your profile changes instantly. No polling delay, no stale status hanging around.

No Discord login

Syncr talks to the Discord desktop app over local IPC. You never hand a token or password to an extension.

Nothing leaves your PC

No accounts, no servers we run, no analytics. The whole pipeline lives between your browser and your desktop.

You control every site

Toggle each activity on or off from the popup. Share only what you want, hide the rest in one tap.

Built-in updater

Syncr checks for new versions and updates itself in place. No waiting on a store review queue.

Free and open source

Every line is on GitHub under a permissive license. Read it, fork it, ship your own activities.

How it works

Two small pieces, fully local

Your page never talks to a server we run. The whole chain lives on your own machine.

01

Firefox tab

You browse a supported site like you normally would.

02

Content script

A tiny script reads just the fields needed for presence, right there in the page.

03

Local host app

A small native app maps it to a Discord activity, then hands it to the desktop app over IPC. No login, no token.

04

Discord profile

Your friends see a live, detailed status. That is the whole trip.

Supported sites

The sites you already use

Four activities today, each reading only what it needs. More on the way, and anyone can add their own.

YouTube MusicListening

Now playing with track, artist, album art, and a live progress bar.

Shows: Track · artist · artwork · progress

YouTubeWatching

The video you are watching, with its title and channel.

Shows: Video title · channel

RedditBrowsing

The post or subreddit you are on, or a simple browsing status.

Shows: Post · subreddit, or "Browsing"

Proton MailPrivacy-first

A deliberately generic "checking mail" status. No subjects, no senders, ever.

Shows: Generic mail status only
