Comparison
BusyWait and Calendly
These are not the same kind of product, and most comparisons between them are unhelpful because they pretend otherwise. Calendly is a scheduling platform: its centre of gravity is the booking experience, the forms in front of it and the workflows behind it. BusyWait is a calendar sync tool that also gives you a booking link.
The distinction matters most if you have several calendars. Calendly can check more than one calendar for conflicts before it offers a slot. It does not keep those calendars in step with each other — book something directly in your personal calendar and your work calendar still shows the time as free to anyone looking at it. That gap is the thing BusyWait exists to close.
Credit where it is due
What Calendly does better
Written first, because a comparison that never concedes anything is not worth reading.
- Scheduling depth. Routing forms, screening questions, workflows, reminder sequences, group and collective events, embedded booking on your own site — Calendly has years of that and BusyWait has none of it.
- Integrations. If a booking needs to create a CRM record, fire a webhook into a tool you already run, or take a payment at the point of booking, Calendly does that and BusyWait does not.
- Teams at scale. Round-robin across a large group, admin controls, seat management and reporting are built for organisations rather than for one person with too many calendars.
- Being known. Sending a Calendly link needs no explanation. That is worth something real when the person booking is a stranger.
Side by side
The differences that decide it
| Calendly | BusyWait | |
|---|---|---|
| What it is for | Letting other people book time with you, at depth | Keeping your own calendars in step, with a booking link on top |
| Sync between your calendars | Checks calendars for conflicts; does not mirror events between them | Two-way mirroring, so a booking in one blocks the time in all of them |
| Calendar providers | Google, Outlook and iCloud | Google, Outlook, iCloud and any CalDAV server, including Fastmail and Proton |
| Pricing shape | Per seat, with the useful features on the higher tiers | Flat: free for two calendars, £7/month for one person, £24/month for five |
| AI features | Being added across the product | None, and none planned |
Which one
How to decide
Choose Calendly
Choose Calendly if the booking experience is the product for you — if you need routing, payments, embedded scheduling on a website, deep integrations, or scheduling administered across a team. It does all of that properly and BusyWait does not attempt any of it.
Choose BusyWait
Choose BusyWait if your actual problem is that you have four calendars and no way to reconcile them, and a booking link is the second half rather than the first. Also choose it if you would rather the times crossing between your calendars carried nothing but a start, an end and the word busy.
FAQ
Questions about the two
- Does Calendly sync my calendars with each other?
- No. Calendly can check several connected calendars for conflicts before offering a slot on your booking page, but it does not mirror events between them: an event created directly in one of your calendars is not copied into the others, so those calendars still show that time as free to anyone looking at them or booking through a different route. Keeping calendars in step with each other is a separate job, which is what a calendar sync tool such as BusyWait does.
- Can I use BusyWait and Calendly together?
- Yes, and it is a sensible setup. BusyWait keeps your calendars mirrored so every one of them shows the same busy picture, and Calendly reads whichever calendar you have connected to it. Because the blocks BusyWait writes are ordinary calendar events, Calendly treats them as conflicts like any other and stops offering those times.
