# #1 Cal.com

Cal.com is an open-source scheduling platform for booking links, team and round-robin scheduling, available as a hosted service or self-hosted. Website: cal.com. Category: [Scheduling & Lead Routing](https://gtmranked.com/best/scheduling-routing/). Score 52/100 (15 positive, 2 mixed, 5 negative of 22 independent comments).

**Verdict:** Independent users treat Cal.com as the free or cheap Calendly alternative: the free tier covers most of what solo users need, it syncs several Google and Outlook calendars without double booking, and several users prefer it to Calendly. The trade-offs are setup effort, since its flexibility takes more configuration than people expect, and costs for advanced needs such as OIDC or enterprise features, plus isolated reports of O365 busy-status sync failing and reminder emails not landing. About a quarter of the Reddit mentions are promotional, mostly self-promotion posts that carry the poster's own cal.com booking link or plug another product.

**Best for:** Solo founders, consultants and freelancers who want a free booking link; Small teams that want round robin for less than Calendly; Developers who want an open-source, self-hostable scheduler.
**Skip it if:** Teams that want a no-setup tool and won't spend time configuring; Buyers who need enterprise features or SSO on a small budget.
**Pricing (vendor-stated, checked 2026-10-15):** Free plan for 1 user with no usage limits. Teams $12/user/mo and Organizations $28/user/mo, billed yearly (yearly saves 25% versus monthly); both have a 14-day free trial. Enterprise is custom, annual pricing.
