# Cirrux - **Website:** - **Primary alias:** `cirrux.co` ## Description Cirrux is an independent, subscription-funded workspace created by Rick Pastoor for people and teams seeking a modern, privacy-conscious alternative for everyday work. Its suite brings together email, calendars, reminders, contacts, and file sharing, with fast apps for mail, calendar, and files. Users can create mailboxes on their own domains or use a Cirrux.me address, manage aliases, set server-side email rules, and collaborate through shared mailboxes. Files and folders can be shared by link or with named users, with permissions that can be changed or withdrawn. Cirrux also supports established standards, including IMAP, CalDAV, and CardDAV, so customers can use compatible clients such as Apple Mail or Thunderbird. A documented HTTP API and open-source command-line tool provide access to workspace features and can support AI agents. Cirrux offers backup and migration tools to help customers move from existing providers at their own pace. Data is hosted on European servers, encrypted in transit and at rest, and the service says it does not use email content for advertising or tracking. ## Industries - 🖥 Computers Electronics and Technology - 🖥 Email _(under Computers Electronics and Technology)_ - 🖥 Cloud Services and Computing _(under Computers Electronics and Technology)_ ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idTZ-3I2sz/w/512/h/512/theme/light/logo.png?c=1bxid64Mup7aczewSAYMX&t=1791160556830) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Terracotta | #e5826b | accent | | Black | #000000 | dark | | White | #ffffff | light | ## Fonts - Geist — asset _(google)_ - Geist — asset _(google)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
