What works the same as Google Calendar

  • One week view over all your linked Google accounts.
  • Link more Google accounts with the Add Google account button.
  • Calendar behavior is written from a spec of how Google Calendar works.

What is missing

  • It is a personal app: only allowlisted Google emails can sign in.
  • It has no public site or release: you deploy it yourself.

How to get started

  1. There is no installer: you set it up yourself with Node and pnpm.
  2. In the project folder run pnpm install, then pnpm dev.
  3. The dev version uses fake Google accounts, so it needs no keys; for real accounts you deploy it yourself with your own Google keys.
