The short version: Google Calendar's free appointment slots, Calendly's free tier, Setmore, Square Appointments, Fresha, and Cal.com are the six free booking tools worth your time in 2026. None of them are free forever if your business grows, and the one that costs you nothing on the pricing page might cost you the most in payment fees or lost bookings. Pick based on how you take payment and how many staff you've got, not on which one your mate uses.

Why "free" is doing a lot of heavy lifting here
Every business tool company has worked out that giving away a booking calendar is the cheapest way to get inside your business. Once your clients are used to booking through Setmore or Calendly, moving becomes a pain, so they can afford to give you the basic version for nothing and wait for you to grow into a paid plan. That's not a criticism, it's just how the model works, and it means the free tier is often usable, not a stripped down demo designed to annoy you into upgrading within a week.
I've set up booking systems for coaches, hairdressers, a physiotherapist, and my own consulting calendar over the past few years, and I've watched clients pick a tool based on a Google search, get three months in, and then discover the limit they hit was the one thing they needed. So before the list, one bit of process: work out how you take payment, how many people need their own calendar, and whether you need reminders sent by text or just email. That takes ten minutes and saves you a re-set-up later. If you're building anything else automated around your booking flow, this is worth doing before you touch any tool, and I've written a longer version of that thinking in how to prepare your small business for AI automation before you buy any tools, most of which applies just as well to something as small as a booking calendar.
Google Calendar's appointment slots (the one people forget is free)
If you're a one-person business and you already live in Gmail, you don't need a separate booking tool at all. Google Calendar's "Appointment schedules" feature lets you block out chunks of time, set a duration, and share a booking link. Clients pick a slot, it lands straight in your calendar, and you get an email confirmation. No monthly fee, no branding to fight with, no upgrade nag screens.
The catch: it's built for one person's calendar, not a team, there's no card payment built in, and the booking page looks exactly like every other Google Calendar booking page because there's almost nothing to customise. I used this for eighteen months when I was doing one-to-one consulting calls and it did the job without a single complaint from a client. The day I started running workshops with a colleague and needed two calendars to sync, I moved on.
Calendly's free plan: what you get
Calendly is the name most people say first, and the free plan is real: unlimited one-to-one meetings, one event type, one connected calendar, and reminder emails. For a freelancer, a consultant, or a tutor taking one type of booking (a discovery call, a tutoring session, a fitting), it's more than enough. It integrates with Zoom and Google Meet without any faff, which matters if half your bookings are video calls.
Where it bites: one event type on the free plan. If you want a 15-minute call and a 60-minute session as separate bookable options, you can't have both without upgrading to the paid tier, which starts at roughly £8 to £10 a month per user depending on which plan and how many extras you add. I've had two clients hit this exact wall within their first month and both assumed the free plan would flex more than it does. It won't. Read the limit before you build your website booking page around it, especially if you're linking it from a site you built on Wix or WordPress, both of which handle embedded booking widgets slightly differently, something I cover in Wix vs WordPress for a small business website.
Setmore and Square Appointments: free plans built for small teams
If you've got staff, these two are the better starting point than Calendly. Setmore's free plan covers up to four staff members with their own calendars, unlimited appointments, and a basic booking page, which makes it a solid fit for a small salon, a clinic, or a driving school with a couple of instructors. It also has a free mobile app that staff can check without needing a laptop open, which sounds small until you've watched a hairdresser trying to log into a desktop site between clients.
Square Appointments is free for a single location and one staff member, with no monthly charge at all if that's all you need. The thing to know before you touch it: Square makes its money on the card payment side, not the booking side, so if clients pay through Square when they book, you're looking at around 2.6% plus 10p per tap payment in the UK. That's not a hidden cost exactly, it's on their pricing page, but it's easy to miss when you're focused on the word "free" at the top of the screen. Add a second staff member and the free plan runs out fast, pushing you to their paid tier at roughly £35 to £45 a month.
Fresha: free forever, but read what "free" means for a beauty or wellness business
Fresha is the one I recommend most often to hairdressers, beauty therapists, and massage therapists, because it's free with no monthly subscription at all, not even a capped free tier that pushes you towards a paid one. You get unlimited staff, unlimited bookings, online payments, SMS reminders, and a listing on their own marketplace where new clients can find you.
Here's the bit that doesn't get said enough: Fresha makes its money from payment processing fees on every transaction, and if a client books you through Fresha's own marketplace rather than your direct link, they charge a client acquisition fee that can run to 20% of that first booking's value. For a business built entirely on repeat clients booking direct, that's close to irrelevant. For a new business relying on Fresha's marketplace for a chunk of its new client flow, that 20% adds up fast and it's rarely mentioned in the "completely free" headline that gets repeated across every list like this one. Read their current fee schedule before you commit your whole client list to it, because it does shift and what I've quoted here is what I've seen most recently rather than a fixed number you should bank on.
Cal.com: the open source option, if you don't mind ten minutes of setup
Cal.com is worth a mention because it's open source, meaning you can self-host it for nothing if you've got a developer or a bit of technical patience, or use their hosted free tier which covers unlimited event types for one user, which already beats Calendly's free plan on that one point. It plugs into Google Calendar, Outlook, and Zoom, and the booking page can be styled to match your brand more closely than most of the others on this list allow for free.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
It's not the right pick if you want something you can set up in five minutes and never think about again. It rewards a bit of fiddling, and if that's not you, Setmore or Calendly will get you moving faster.
The step by step way to choose in an afternoon
- Write down how many people need their own bookable calendar. One person: Google Calendar or Calendly. Two to four: Setmore. More than that, or a salon-style business: Fresha or Square.
- Decide if you're taking card payment at the point of booking. If yes, check the payment processing percentage before anything else, because that's the number that scales with your revenue, not a flat fee.
- Check if you need more than one type of appointment (a 15-minute call and a 60-minute session, say). If you do, cross Calendly's free plan off the list straight away.
- Set it up with real dummy bookings for a day before you send the link to a single client. I've seen reminder emails land in spam and time zones default wrong more times than I'd like, and it's always easier to catch on a test booking than explain to a client why they missed a call.
- Put the booking link everywhere your clients already look: your email signature, your Instagram bio, your website. If your booking page is going to sit on a business site rather than a link in bio, it's worth reading through the free alternatives to paid marketing tools I've put together separately, because most of the booking tools above sit inside a wider free stack that can replace a surprising amount of paid software, covered in best free alternatives to expensive marketing tools.
A quick story about switching twice in one year
A coaching client of mine started on Acuity's trial, moved to Calendly's free plan when the trial ended because it was, in her words, "the one everyone recommends," then hit the one-event-type wall three weeks later because she runs both discovery calls and paid strategy sessions. She moved to Setmore. Every switch meant re-sending a new booking link to an existing client list, updating her website embed, and losing the booking history from the old tool, which meant no clean record of who'd booked what and when. None of that is a disaster, but it's an afternoon of admin each time, and it's entirely avoidable if you map out what you need before you pick, rather than picking the tool everyone else mentions first and working backwards from there.
The uncomfortable bit nobody likes saying out loud: the booking tool is rarely the thing standing between you and more revenue. I've watched businesses spend two weeks agonising over Calendly versus Setmore while their actual no-show rate sat at 20% because nobody had set up a text reminder, free or paid. Pick a free tool that covers your basics, turn on reminders, and move on to the parts of your marketing that will shift bookings, which usually has more to do with what happens before someone lands on your booking page than which calendar tool processes the click.
Where a booking tool overlaps with a chatbot (and where it doesn't)
A fair few small businesses now run a website chatbot that answers questions and then hands the visitor a booking link at the end of the conversation, which works well if the chatbot is doing a proper job of qualifying the enquiry first rather than just being a glorified FAQ box. If you're thinking about adding one alongside your booking tool, it's worth reading through what makes a chatbot useful rather than annoying, which I've laid out in AI chatbots for small business websites: the honest guide to getting it right. Tutors and coaches in particular tend to combine the two well, since a chatbot can answer the "how much" and "how long" questions before a client even reaches the booking calendar, something that comes up a lot in the world of online tutoring jobs you can do from home, where booking friction is often the single biggest reason a good tutor stays half-booked.
Frequently asked questions
What's the best completely free booking tool for a one-person business?
Google Calendar's appointment slots or Calendly's free plan, in that order. Google Calendar if you only need one type of appointment and already use Gmail, Calendly if you want a slightly more polished booking page and don't mind the one-event-type limit.
Is Fresha really free, or is that a marketing line?
The booking and scheduling side is free with no monthly fee. Fresha makes its money on payment processing fees and on client acquisition fees when a new client books you through their marketplace rather than your own direct link, so check their current fee schedule before relying on the marketplace for new client flow.
Which free booking tool works best for a small team, not just one person?
Setmore, for up to four staff members on the free plan with unlimited appointments. Beyond four staff, or if you're a salon-style business taking card payment at the point of booking, Fresha or Square Appointments tend to fit better.
Do free booking tools handle payment, or just scheduling?
Most handle both, but the payment side is where they make their money rather than the scheduling side. Square and Fresha both charge a percentage on card payments taken through their systems, so check that number before assuming the whole tool costs you nothing.
