Vojo — Matrix-based messenger for the Russian market

What is this

This is a fork of Cinny (https://cinny.in, MIT license) rebranded as Vojo. Vojo is an independent messenger built on the Matrix protocol, targeting Russian users affected by Telegram blocking.

Key value proposition: "Telegram works without VPN" — the server maintains Telegram bridge connections, users just open vojo.chat and chat.

Architecture

Domain: vojo.chat
Server: Yandex Cloud VPS, Ubuntu 24.04
Backend: Synapse (Matrix homeserver) + PostgreSQL + Caddy (reverse proxy)
Bridges: mautrix-telegram (Python v0.15.3, SOCKS5 proxy for Telegram)
Client: This repo — Cinny fork, deployed as static files via Caddy

The client is served from ~/vojo/cinny/ on the server. Caddy serves it at https://vojo.chat.

Branding

Name: Vojo (everywhere in UI, page titles, meta tags)

Default homeserver

All configs must point to vojo.chat as the default and only homeserver. Hide homeserver selection from the user — they don't need to know about Matrix.

Build & Deploy

npm ci
npm run build
# Output in dist/
scp -r dist/* vojo-superuser@111.88.146.156:~/vojo/cinny/

Caddy serves from /var/www/cinny (symlinked to ~/vojo/cinny).
