Cal.com

Overview

Cal.com is the Calendly alternative you can own. The core is open source and self-hostable, the hosted version is free forever for individuals, and the platform tier exposes the API and white-label pieces that let a product embed scheduling instead of linking out to it. The 2026 addition is Cal.com Agents: AI that takes "find us 30 minutes next week" in Slack or Telegram (email is marked coming soon) and resolves it against real availability; the Slack and Telegram agents are free with an account, and AI Prompts is a Pro feature. Pricing is published and simple — Teams at $12 per user, Organizations at $28, both discounted 25 percent on yearly billing — and reviewers give setup and support high marks. The honest caveats: initial configuration is more complex than Calendly for non-technical users, the Agents credit model is not spelled out on the page, and the company has not announced new funding since 2022, which matters if you are standardizing a product on it. Buy Cal.com if you want to self-host, embed scheduling through an API, or stop paying per seat for a booking link. Buy Calendly if you want the polished default with no decisions to make, or Motion or Reclaim.ai if the problem is optimizing your calendar rather than letting other people book it.
