Which one can your own booking site actually build on?
If your own website is going to take the booking itself, build on Guesty. Both stop a double booking while a guest is entering a card number. Hostfully takes the room off your calendar the moment a guest starts booking, and it stays off through every stage of that booking until it's confirmed, canceled, or released, according to Hostfully's own documentation. Guesty holds the room the same way, through what it calls a quote. Past that point they differ in what each one tells your site when something goes wrong. If you are still choosing the property system itself, Choosing a PMS for a small hotel, inn or serviced apartment: what connecting to it actually lets you build is the decision above this one.
Your own booking site needs to show the exact same bookings your staff already see, updated the moment a guest books. It also needs to hear about changes that happen elsewhere just as fast, like a reservation that came in on Airbnb an hour ago. Guesty is explicit about how fast this has to happen: your site has 15 seconds to confirm it caught the update and keep the calendar in sync, or Guesty treats the connection as failed and tries again.
Hostfully vs Guesty side by side: what matters for your booking site
Hostfully is the only one that prints its price at 8 to 25 units, and Guesty is the only one that spells out what happens when a connection drops.

What does Hostfully cost compared to Guesty?
Guesty's $9 Lite plan stops at three listings, so at 8 to 25 units you're forced onto Guesty Pro, which is priced only through a call with sales. Hostfully's own comparison page says Guesty "commonly starts around $35 to $40 per property", a vendor's claim about a rival rather than a figure Guesty prints.
Hostfully takes no cut of your direct money from Pro upward. Growth, the cheaper plan you're usually quoted first, carries a 1% payment gateway fee plus a 0.85% direct booking fee on every direct booking, both printed on Hostfully's pricing page and checked on September 2026.

Nothing, on either line |
| Guesty |
An application fee per transaction, at a percentage it does not publish |
At 20 units, Pro costs $200 a month more than Growth, $500 against $300, and Growth's 1.85% passes $200 once you take about $10,800 a month through your own site. Get the platform fee in writing first, because neither plan publishes it.
On Guesty you cannot do that arithmetic at all. Guesty's help page on gateway fees confirms the fee sits on top of the card processor's charge and that Stripe collects it for Guesty, so it shows in your own Stripe dashboard as a line called Guesty Application Fee rather than on your Guesty invoice, at a percentage on no Guesty page we could read.
How each one handles a dropped connection once your site takes the booking
Say your website goes offline for ten minutes right when a guest books through Airbnb. The two systems handle that gap very differently. Guesty publishes the whole retry schedule: immediately, then 5 seconds, 5 minutes, 30 minutes, 2 hours, 5 hours, 10 hours and 10 hours again, roughly 27 hours of trying, and it stops sending updates entirely once the failures run for 5 days straight. Hostfully's own documentation explains what booking details it sends but says nothing about retrying a missed delivery. On Guesty, that booking still lands on your calendar once the connection comes back, just later than it should have. On Hostfully, going by what its own documentation actually says, that booking would never make it onto your calendar at all.
Maxine and I run MINT @Naschmarkt in Vienna, 18 serviced apartments sold as five apartment types, and Hostfully has run the property side of it for years. Our booking page spent part of last year turning guests away from nights we had free. 5 of 30 nights looked bookable before the fix; 26 of 30 after. The cause was that Hostfully lumped every room of a type together: the moment a guest booked just one physical room, it marked the whole type sold out for that night, hiding every other identical room that was still sitting empty and could have been sold. We already had developers on hand, so rather than wait for Hostfully to change how it counted, we built a layer above the property system that recalculated availability correctly ourselves. Hostfully confirmed that this under reporting is deliberate. It keeps no availability count and no per unit calendar. Guesty instead shows you a running count of how many identical units are free each day.
Guesty's own fee is charged per transaction, so a reservation with one payment and three declines carries a charge on each valid attempt. We priced that risk for our own migration at about 1% to 3.5% in outside examples, unpublished by Guesty itself, billed even on a declined attempt, against a Hostfully Pro plan that charges no per transaction fee on the direct money path at all.
Checking your calendar from your phone
Between check-ins is when this actually matters. Hostfully's own pricing page lists a mobile app as part of what Growth includes, at no separate charge. Guesty's pricing page doesn't list a comparable app feature the same way, so if running things from your phone matters to how you work day to day, ask each vendor to show you directly before you sign.
A ten minute test on your own booking page
- Pick a night where one unit of a type you sell several of is sold and the rest are free.
- Search that night on your own booking page the way a guest would, asking for that type.
- If nothing comes back available, nights like it have been going unsold without anyone telling you.
If Guesty is where you land, how to build a direct booking page on Guesty covers what information it hands your checkout page during a booking.
Is it worth switching from Hostfully to Guesty?
A move to Guesty makes sense once your own website is about to start taking the booking itself, or if Hostfully's habit of lumping identical rooms together might already be hiding rooms you could be selling right now. For most operators at 8 to 25 units, selling almost everything through the platforms, neither one applies yet.
| Your property |
What I would do |
| 8 to 15 units, nearly every booking through the platforms, nobody technical on staff |
Stay on Hostfully Growth at $15 a property a month. A dropped connection or a multi room availability mixup won't change your month at this size, and the 1.85% applies to very little money |
| 15 to 25 units, already taking some money on your own domain |
Run the ten minute test first. If the calendar under reports, fix that before anything else; if it does not, move up to Hostfully Pro and keep your direct money whole |
| Either size, building a custom checkout this year |
Build on Guesty, and carry the application fee as an unknown in the budget, because nobody will show you that number in advance |
If you are still not sure
Our own move is planned in stages. Guesty takes over the calendar first, while payments keep running through our own setup exactly as they do today, and we only hand Guesty more of the work once each piece has proven itself. That first stage takes 4 to 6 weeks of development, then another 2 to 4 weeks running the new setup alongside the old one to prove it works before we trust it fully. We ourselves had first guessed the whole migration would take 3 to 4 months end to end, before we scoped it this closely. Every part of the website a guest actually sees stays ours, because we never need to fall back on the property system's own ready-made booking pages. We run MINT from Austria, where Booking.com doesn't enforce rate parity. Your contract in the United States or Canada is stricter than ours, so these fee lines eat into your bookings more than they eat into ours.
We do the direct booking side for you, sitting over whichever of these two you keep, and it is usually taking bookings within three weeks. Properties at around $350,000 a year of bookings or more are where the commission we save pays for the work. Bring whichever system you are leaning toward and we will say plainly what it will not do for your checkout. Book a call: twenty minutes, prepared for your own unit mix.
