The short version
- What they share
- A small, fast menu bar calendar with a month grid and an agenda, week numbers, and a deliberately quiet menu bar item.
- Accounts
- Itsycal shows the calendars macOS already knows about. InstaCal does that too, and can also sign in to Google and Microsoft 365 directly.
- Creating events
- InstaCal adds plain-English entry with a live preview, plus a full event editor with repeat rules, multiple alerts and attendee invites for direct Google and Microsoft calendars.
- Meetings
- InstaCal detects Zoom, Google Meet, Microsoft Teams, Webex and other links and keeps Join available until the meeting ends.
- Invitations
- InstaCal flags schedule conflicts; directly connected Google and Microsoft accounts can accept, decline or answer tentatively inline.
- Cost
- Itsycal is free. InstaCal is $29 once.

Compiled July 2026. Itsycal is actively developed and deliberately minimal — several of these gaps are design decisions, not omissions.
When Itsycal is the right choice
If what you want is a month grid and a glance at today, Itsycal does that beautifully, costs nothing, and has been doing it well for years. Paying for InstaCal to get the same thing would be a waste of $29, and we would rather say so here than take the money.
The case for InstaCal starts when the panel becomes somewhere you act rather than only look: creating the event by typing a sentence, answering a direct-provider invitation, joining the call.
