Alps Webmail
Minimalist open source webmail in Go
Alps Webmail is a minimalist, stateless webmail client designed for modern IMAP infrastructure. Built with simplicity, speed, and extensibility in mind, it avoids central databases and heavy frameworks, making it ideal for scalable deployments and low-maintenance environments. Alps supports multi-tenancy, responsive theming, CalDAV/CardDAV integration, and a lightweight plugin system using Lua or Go. It is already used by thousands of users and aims to become the default webmail layer for self-hosted and provider-grade email platforms, emphasizing usability, transparency, and long-term sustainability.
