Plain files

Every event is stored as an .ics file on your machine. It works offline, is human-readable, and can easily be backed up.

Syncs with any provider

Connect to Google Calendar, iCloud, Outlook, and CalDAV servers through a growing ecosystem of provider plugins.

Natural input

Type events the way you say them: "lunch with Sarah tomorrow at 1" or "team sync every Monday"

Agent-friendly

Your calendar is just a directory. Use grep, shell scripts, git, or the caldir CLI. No complex MCP servers needed.

Keyboard-first

Move around with Vim-style navigation and shortcuts built for power users.

Omarchy native

Built for Omarchy Linux, with themes that adapt to the color palette of your system.


Free and open-source

No subscriptions. No enshittification. Built in the open.
