The 5 best Calendly alternatives, compared honestly.
Calendly is a polished booking link. But if you run your week across two or more calendars, the right alternative depends on what you actually do. Here is the short answer, then the full breakdown.
The short answer
BookTime is the best Calendly alternative for solo professionals who run multiple calendars, because it unifies Google, Apple, and Outlook into one conflict-aware view. Cal.com is best for developers who want open-source, self-hosted scheduling; Acuity is best for service businesses that sell packages and take payments; Square Appointments is best for retail and in-person businesses already on Square; and Calendly itself remains best for sales teams that need round-robin lead routing.
5 Calendly alternatives, ranked by who they are for.
Best overall for multi-calendar professionals
BookTime unites your Google, Apple, and Outlook calendars into one view, so you never get silently double-booked across the accounts you actually run — then hands clients a clean booking page on top. It is the only tool on this list built around the unified-calendar problem rather than a single booking link.
Best open-source alternative
Cal.com is the open-source challenger — self-hostable and API-first. If you have the technical chops, you can run it on your own infrastructure with full data residency, or use the hosted plan and white-label everything.
Best for service businesses
Acuity (owned by Squarespace) goes beyond a booking link into full appointment management — gift certificates, memberships, payment plans, and detailed client intake. For service businesses already on Squarespace, it is effectively bundled.
Best for retail and in-person businesses
Square Appointments ties booking directly to Square’s point-of-sale and payments stack. If you take payments in person and already use Square, scheduling sits inside the same system you ring up sales with.
Still best for sales teams
Calendly earned its reputation for a reason — it is the most polished single booking link on the market. Where it shines is team distribution: round-robin routing, lead-qualification forms, and native CRM integrations make it strong when scheduling is a conversion event for a sales team.

Calendly alternatives, answered.
BookTime is the best Calendly alternative for solo professionals who run multiple calendars, because it unifies Google, Apple, and Outlook into one conflict-aware view and adds clean booking pages. Cal.com, Acuity, and Square are stronger for developers, service businesses, and retail respectively.
Cal.com offers the most generous free plan, with unlimited event types for individuals and a fully free self-hosted open-source version. BookTime is also free during its beta, and Square Appointments has a free tier for individuals in the Square ecosystem.
Cal.com is the best open-source Calendly alternative. It is self-hostable and API-first, which lets developers run scheduling on their own infrastructure with full data control or embed it directly into their own product.
BookTime is the Calendly alternative built specifically for this. It merges Google, Apple, and Outlook calendars into one unified view and catches double-bookings across separate accounts, which a single Calendly booking link does not do.
Cal.com and Square Appointments both have free tiers, and Cal.com can be self-hosted at no software cost. Among paid plans, BookTime is $8/month flat rather than per-seat, which is cheaper than Calendly’s $10–$16 per-seat pricing for individuals.
Sales teams should still consider Calendly. Its round-robin distribution, lead-routing forms, and native HubSpot and Salesforce integrations make it strong when scheduling is a team conversion event rather than personal multi-calendar management.
