Mitra

One calendar to plan your events and tasks

Want to look around first? Try the demo: you get a calendar of your own with sample entries, and nothing to install.

Features

• Events and tasks on one timeline, in week, month, year, timeline and table views. Drag to create, move and resize anything.
• Calendars stored in Mitra itself, with no account behind them, or synced both ways with CalDAV, Google Calendar, Apple Calendar, Notion and Tempo. Published calendar feeds come in as read-only subscriptions.
• Planning: tasks without a date wait in the Planning tab with a due date and an estimate, until you drag them into your week.
• Availability, subtasks and dependencies, files attached to entries, reminders as push notifications, guest lists with replies, and a command palette for the keyboard.
• AI connectors: Claude, Cursor and other AI tools can read and plan your calendars over the Model Context Protocol (MCP).
• Eight languages, right to left included, light and dark themes, and a color for every calendar.
• One small container with a database you own, no telemetry, and sign-in for several people when you need it.

Get started

# compose.yaml
services:
  mitra:
    image: ghcr.io/a11delavar/mitra:latest
    restart: unless-stopped
    ports:
      - '3000:3000'
    volumes:
      - ~/mitra:/app/data
    # environment:
    #   MITRA_URL: 'https://mitra.example.com' # once Mitra has a public address

docker compose up -d   # → http://localhost:3000

Out of the box, Mitra is for one person and has no sign-in. Everything it stores is in the ~/mitra folder, so backing that up backs up everything.

From here, the documentation covers your first calendar, connecting accounts, sign-in for several people and everything else. You can also read it as Markdown in docs/.
