Python3. Main JSON-RPC server and WebSocket server for push notifications (with help of Werkzeug, psycopg2, aiohttp, lxml).<p>Frontend. ES6. Single-page application based on vuejs. Also it used less as CSS preprocessor and browserify for bundling up all dependencies.<p><i>For clarification</i><p>Mailur doesn&#x27;t have support arbitrary IMAP server yet, but it has basis for implementing this, just need more time for development and testing. It has bidirectional synchronization for Gmail through IMAP.<p>Maybe it would be more accurate to say this is a Roundcube replacement with Gmail inspiration. But for me it is Gmail replacement, because I have used it over 8 years and want to bring Gmail experience to open source.
