SnappyMail is a web-based email client developed as a fork of RainLoop. It provides a responsive interface for reading, composing and organising messages stored on existing mail servers.
The application was created to modernise RainLoop’s architecture, improve security and remove outdated dependencies. Its design favours a lightweight interface, with support for a range of mail server capabilities and additional functionality through extensions.
SnappyMail can be deployed as a standalone webmail service or integrated into other environments. It is particularly suitable for individuals and organisations seeking direct access to IMAP mailboxes without adopting a larger collaboration platform.
This is free and open source software.
