Calendly Standard, 3 seats → Cal.com, self-hosted
Stay. At $50 an hour, Cal.com costs you $1,395 more over 3 years.
This one only pays off if your hour is worth less than
$10.14/hrThat is below the minimum wage almost anywhere this software is run. In practice it means stay on Calendly Standard: the subscription is cheaper than the hours Cal.com would take, and it is not close.
Every figure on this page updates as you move these. Most comparisons of this kind quietly assume your time is free and your team never changes size.

What you give up, and what you get
You lose
- Calendly's polish, particularly on mobile booking pages
- Managed calendar-sync reliability — OAuth tokens to Google and Microsoft are now yours to keep alive
- Some routing and workflow features gated behind Cal.com's own commercial licence
You gain
- Free seats, which is the whole argument once you pass a handful of users
- Booking data in your own database
- AGPL-3.0 for the core product
Read this before you decide
- Cal.com self-hosted is a Next.js monorepo and is heavier to run than its feature list suggests. The 4 GB requirement is not padding.
- Parts of Cal.com are under a commercial licence rather than the AGPL core. Check the /packages/features/ee directory against what you need before committing.
- Google Calendar OAuth setup is fiddly and is the most common place this migration stalls.

Hosting requirements (2 vCPU, 4 GB RAM, 30 GB disk), migration hours and maintenance hours are our estimates, not measurements. They are the numbers most worth arguing with, so we put them where you can see them. The cheapest plan meeting those requirements is selected automatically from Vultr, Vultr and Linode's live catalogues.
