Aurora Calendar

Overview

Aurora Calendar is a self-hosted calendar that runs entirely on hardware you control. It aims to match Google Calendar feature for feature and go beyond it, while keeping every piece of data - events, reminders, and even email parsing - on your own server.

Try a live slice of it

This is a small, self-contained piece of Aurora running right here in the page. Click an email in the inbox to scan it (the real app uses a local LLM; here the result is simulated), approve or dismiss the proposal, and drag events around the week. Nothing leaves your browser.

Email to event, with your approval

Aurora reads your mailbox over read-only IMAP and hands incoming emails to a local LLM running on your own machine. Extracted events are never added automatically - each one lands in a review queue as a proposal you approve, edit, or dismiss. No email content is ever sent to a third-party AI API.
