Is Caletus a good Cal.com alternative?

Yes, if you don't want to self-host. Caletus Professional is $6 per user a month billed yearly, and Enterprise, which adds round robin, is $12. Cal.com Teams is $12 as of October 2026. Both take AI notes only in their own video calls. Cal.com is the better pick if you want a more generous free plan, reminder workflows or to self-host with Cal.diy.

Is Cal.com still open source?

Not the main product. Cal.com announced in April 2026 that it was going closed source, and relaunched its free code as Cal.diy under the MIT license for self-hosting. Caletus isn't open source either. It's a hosted service, audited under SOC 2 Type II.

Can I self-host Caletus?

No. Caletus is hosted only, so there are no servers to set up or patch. It's SOC 2 Type II audited, and Enterprise includes a 99.99% uptime SLA. If self-hosting is a hard requirement, Cal.diy, the MIT-licensed edition of Cal.com, is the better fit.

Does Cal.com have AI meeting notes?

Partly. As of October 2026, Cal.com Notes writes AI summaries of calls held on Cal Video, Cal.com's own video tool, and is rolling out through a waitlist. Caletus's AI notetaker works in Caletus video calls on the Professional plan, so neither tool takes notes in Zoom calls.

Which tool is easier for non-technical teams?

Both hosted products are easy to start with. You can set up a first Caletus booking link in a few minutes, with no code, API keys or servers. Self-hosting Cal.diy is a job for a developer.
