How Cal.com and Substack compare

Cal.com is scheduling infrastructure you can own. Open source and self-hostable, with calendar sync across Google, Outlook, and iCloud, event types, round-robin and collective team booking, routing forms, workflows for reminders, payments at booking, and an API and embeds developers actually like. Individuals get a generous free plan.

Substack made paid newsletters normal. You write, it sends, and readers can subscribe or pay in one click. The network effects are real: recommendations, Notes, the app, and discovery bring new readers you did not have to find. There is no monthly fee, and for a writer who wants to write rather than run software, that is a gift.
