Cal.com vs Acuity Scheduling: an honest comparison for choosing a scheduling tool
Cal.com and Acuity Scheduling solve the same core problem - letting people book time with you without the back-and-forth - but they come at it from opposite ends. Cal.com is open-source, developer-leaning, and built to be owned, embedded, and scaled across teams. Acuity is a polished, service-business product owned by Squarespace, with deep intake forms, packages, and class booking out of the box. Neither charges a commission on your bookings. The right choice depends on who is setting it up, how technical your team is, and whether data location and per-seat cost matter to you. Here is a fair side-by-side, followed by clear guidance on when each one wins.
Cal.com is an open-source scheduling platform (AGPLv3) aimed at developers, technical teams, and businesses that want to own their data or build scheduling into their own product. It runs as a hosted cloud service or can be self-hosted for free on your own infrastructure. The free tier is genuinely generous - unlimited event types and calendar connections, plus integrations and payment collection - while team and organization features are billed per seat. There is no per-booking commission; paid appointments run through your own Stripe or PayPal account. The trade-off is a steeper learning curve for non-technical users, and the fact that the standard cloud is US-hosted, with the EU-resident option (cal.eu) rolling out from early access toward general availability.
Acuity Scheduling is a US-based, Squarespace-owned booking platform built for solo practitioners and small service businesses - coaches, salons, wellness providers - who want intake forms, payments, and class scheduling in one mature package. It is subscription-only with no permanent free plan: you get a 7-day trial, then pay a flat monthly fee per account, with capacity and features (SMS, packages, HIPAA) rising by tier. Acuity takes no commission on bookings; payment processing runs through Stripe, Square, or PayPal at their standard rates. Its depth for service businesses is a real strength, but reviewers note features many consider basic are gated behind higher tiers, the booking page supports only one language per account - though it does ship a handful of ready-made translations (French, German, Italian, Spanish, Japanese, Brazilian Portuguese) - and there is no EU data residency.

Choose Cal.com if
Choose Cal.com if you are technical or have engineering support, want a real free tier or full self-hosting, need to embed scheduling into your own product via APIs and routing forms, or care about owning your data and keeping it in a region you control. It is also the stronger pick if you want to avoid being locked into a closed SaaS and value an auditable, open-source codebase.
Choose Acuity Scheduling if
Choose Acuity Scheduling if you run a solo or small service business - coaching, salon, wellness, classes - and want intake forms, packages, gift certificates, group bookings, and payments working out of the box without any setup effort. It is the better fit if you are already on Squarespace, want responsive vendor support, and are comfortable paying a flat monthly fee once the trial ends.
A third option
If neither end of this spectrum fits - you want Acuity's ease without its price tag and US-only hosting, but not Cal.com's DevOps overhead - Calenkli is worth a look as a third option. It is free to start with a 0% booking fee on every plan, ships fully localized in six languages (English, French, Spanish, German, Italian, Portuguese) - not just the booking page, but the host dashboard, form validation, and custom text too - and is an EU company with data hosted in the EU. Cal.com's routing forms can already qualify and redirect a lead before a slot is taken, so the pre-booking gate itself is not unique; where Calenkli differs is making that conditional logic - questions that can auto-disqualify or redirect a poor-fit invitee before they book - simple to set up out of the box, without the configuration and team or attribute setup Cal.com routing assumes. It is newer and smaller, with fewer native integrations and lighter team features today, so it is a softer fit for large or heavily integrated setups - but for European or multilingual teams who want to screen leads up front without engineering effort, it is a genuine alternative.
Free forever, 0% booking fee, qualification before the booking, and a fully localized booking page in six languages.
Try Calenkli freeFrequently asked questions
Does Cal.com or Acuity take a commission on my bookings?
Neither does. Both charge 0% on the appointments themselves. Cal.com routes paid bookings through your own Stripe or PayPal account, and Acuity uses Stripe, Square, or PayPal. In both cases you only pay the payment processor's standard transaction fees - the scheduling tool takes no cut.
Is there a free plan for either tool?
Cal.com has a genuinely generous free tier for individuals, with unlimited event types and calendar connections, and it can also be self-hosted for free under its open-source license. Acuity has no permanent free plan - only a 7-day trial, after which a paid subscription is required.
Which is better for a non-technical solo business owner?
Acuity is generally the easier starting point for non-technical users. Its interface is built for service businesses and gives you intake forms, packages, and class booking without configuration. Cal.com is more powerful and flexible but has a steeper learning curve, and its advanced features like routing forms and workflows are aimed at technical teams.
Where is my data stored, and does either offer EU data residency?
Acuity is US-based and stores data in the United States, relying on standard contractual transfer mechanisms for GDPR rather than in-region hosting. Cal.com's standard cloud is also US-hosted; its EU-resident option, cal.eu, is rolling out from early access toward general availability, so confirm current status before relying on it. If you self-host Cal.com, you can keep data in the region of your choice.
Can either tool show the booking page in multiple languages?
Acuity supports one language per account on the booking page, with a handful of ready-made translations (French, German, Italian, Spanish, Japanese, Brazilian Portuguese) and manual workarounds for mixed-language audiences - so a single page cannot serve a mixed-language audience. Cal.com supports localization at the platform and self-host level. If a fully localized experience across UI, booking page, and emails is a priority, this is worth testing carefully before committing.
Can I screen or qualify people before they book a time slot?
Acuity collects information through intake or booking forms, but the slot is reserved first and you review the answers afterward - there is no pre-booking gate. Cal.com is different: its routing forms can ask qualifying questions first and, based on the answers, route the booker to a different event type, redirect them to an external URL, show a custom message, or prevent booking entirely before a slot is taken - though setting this up is aimed at technical teams. Calenkli builds the same idea - conditional logic that can auto-disqualify or redirect a poor-fit invitee before they book - into a simpler, non-technical flow.
