Companies Using Acuity Scheduling

I analysed Acuity Scheduling against our September 2026 crawl, and the count is clean. We detect Acuity from its booking widget, an iframe or script served from acuityscheduling.com. In a browser check of 24 random detected sites, all 21 that loaded showed the widget, 19 of them fetching embed.acuityscheduling.com. So the 3,983 domains on this page are live booking forms, and 2,430 of them match a company record. How we tell an embedded widget from a plain link is covered in our guide to technology detection methods.

It is also a floor. A business that sends clients to its hosted booking page on as.me, without embedding anything, leaves no trace on its own site, and those pages all share one domain, which we keep out of the company list. Embeds served from the newer app.squarespacescheduling.com host are a smaller gap: 57 domains, against 2,733 on the classic embed host.

A Squarespace product, measured on Squarespace sites

2,222 of the 3,981 domains where Acuity is live today are Squarespace sites, 55.82%. On most tools a share like that would mean one platform inflating the count. Here it means something else. Squarespace bought Acuity in 2019 and sells it as Acuity Scheduling by Squarespace, and the reverse share is tiny: about 0.2% of Squarespace's roughly 1.08 million sites embed Acuity. This is a vendor selling its own add-on to a small slice of its own customers.

Squarespace sites don't drop it faster, either. Of the domains we have watched drop Acuity since March 2026, about 49% were Squarespace sites, below their 56% share of current users.

"More than half of the sites running Acuity are Squarespace sites, so for most of its visible customers the website and the booking tool come from the same company. Squarespace is the sales channel." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: if you sell to Acuity users, you are selling to Squarespace owners first. Integrations, templates and services that assume a Squarespace site fit more than half of this list; the WordPress quarter needs a different pitch.

Solo practitioners and small clinics

86.01% of the 2,280 matched companies with a known size employ 1 to 10 people, and 11.62% employ 11 to 50. Only 5 have more than 1,000 staff. The founding years point the same way: 77.84% of those with a founding year started in 2010 or later.

The industry chart reads as a list of people who sell an hour of their time. Wellness and Fitness Services leads at 8.89%, then Medical Practices (6.53%), Professional Training and Coaching (5.87%), Individual and Family Services (5.67%) and Mental Health Care (2.76%). Together that is 29.72% of matched companies, and the names fit: ONE Personal Training in Hong Kong, Master Barbers NYC, Burbank Dental, personalEYES in Australia.

The larger names use Acuity for one job each. Claire's runs it on stores.claires.com for in-store appointments, Westgate Resorts on its my.westgateresorts.com portal, and the Australian Financial Review on a single event page, watch-weekend-2026.afr.com.

Sales signal: the buyer is the practitioner. A therapist or trainer running Acuity decides alone and buys on price and time saved. At the large-company end, the useful contact is whoever owns that one booking flow, not IT.

English-speaking markets

The United States has 1,426 matched companies, more than five times the United Kingdom's 259. Australia (163) and Canada (143) follow, then Germany at 41. No country outside the English-speaking world reaches 50.

Sales signal: filter on the US, UK, Australia and Canada and you cover almost the whole list. Outside those four, Acuity is rarely the incumbent a local booking tool has to displace.

Against Calendly: a different customer, counted differently

Calendly customers outnumber Acuity's in our crawl, 179,831 domains to 3,983, about 45 to 1. Two things matter before reading that as a head-to-head. Our Calendly count includes sites that only link to a Calendly page, while Acuity counts only where the widget loads. And they serve different buyers. Squarespace hosts 55.82% of Acuity sites but only 7.8% of Calendly's, per our Calendly profile, where the largest industries are business consulting (9.99%), coaching (6.82%), IT services (6.74%) and software development (6.38%).

Our switching data can't settle which way businesses move. Since March 2026, fewer than 20 domains have switched between the two in either direction, too few to publish as a corridor.

"Acuity and Calendly get compared as if they fight over the same user. Mostly they don't. Acuity sits on a yoga studio's Squarespace site, Calendly on a consultant's WordPress page, and fewer than 20 domains have switched between them since March." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: treat the two lists as separate markets. A Calendly user usually sells meetings; an Acuity user sells appointments, and Acuity lets them take payment at the moment of booking.

The website around the booking form

Beyond the site builder, the stack is thin. The Facebook Pixel runs on 20.6% of live Acuity sites and Google Ads conversion tracking on 7.61%. Email tools show up on few of them; Mailchimp, the most common, is on 4.65%. Payment tools barely appear, PayPal on 2.49% and Stripe on 2.24%, because Acuity takes payment inside its own booking page through Stripe, Square or PayPal, so the processor never loads on the host site.

Sales signal: one in five of these businesses already runs the Facebook Pixel, while email marketing is barely visible. Email tools built for small practices have room here.

What reviewers say

Acuity rates 4.6 out of 5 across 410 reviews on G2. The summary of those reviews praises ease of use first and names limited features as the top complaint, specifically data export, reporting and client records. The mention counts behind it are small, 4 for the top pro and 3 for the top con, so the direction matters more than the counts.

That complaint fits the base. A one-person studio outgrows a booking tool when it adds staff, memberships and years of client history, and that is when export and reporting start to matter. 669 domains have dropped Acuity since we began tracking in March 2026, but nearly half of them were seen on a single visit, so part of that number is noise rather than cancellations, and no rival has yet taken enough of them to show where the rest went.

Sales signal: growing practices with several staff are the ones most likely to hit Acuity's limits. Filter for 11 to 50 employees and you get the 265 companies closest to that point.

Key takeaways

1. 3,983 domains and 2,430 companies, a floor that misses businesses linking only to a hosted as.me page.

2. 55.82% of live Acuity sites are Squarespace sites, sold through the company that owns Acuity.

3. 86.01% of matched companies have 1 to 10 staff, led by wellness, medical and coaching practices.

4. 1,426 matched companies are American, more than five times the UK's 259.

5. Calendly leads the category on 179,831 domains, but its count includes plain links, and its customers lean to consultants and software firms rather than studios and clinics.

How to use this list

Start with the United States and the 1 to 10 employee band, then split by site builder, since the Squarespace and WordPress halves of this list need different integrations. Filter the industry column on wellness, medical practices, coaching and family services for the core archetype, and read the host column before counting enterprise accounts: the large names run Acuity on a single booking subdomain.
