Your cloud, your rules.·tinycld.org

TinyCld is a free, open-source cloud productivity suite offering Mail, Calendar, Contacts, Drive, Text, and Calc apps that speak standard protocols (IMAP, SMTP, CalDAV, CardDAV, WebDAV). It can be self-hosted via a single Docker container or used as a hosted option, and it is also a developer platform for building additional apps on top of the same foundation. Native mobile apps for iOS and Android connect to a user's own server, and a migration tool imports data from Google Takeout.
