Roundcube

Self-Hosted

Open-source webmail client with a modern, desktop-like interface

Overview

Roundcube is a browser-based open-source webmail client designed for self-hosting. It offers a responsive, desktop-like interface with core features like IMAP/POP3 support, drag-and-drop email management, address book integration, spell checking, and MIME attachment handling. Extensible via plugins, it supports customizations for security (encryption), productivity (calendar sync via plugins), and more. Easy to deploy on LAMP/WAMP stacks or Docker, it’s ideal for users seeking privacy-focused control over their email data, avoiding SaaS webmail’s data collection. A reliable alternative to proprietary webmail services for personal or small business use.
