Share one booking link.
The rest fold around it.
busyfold does two things for your Google and Microsoft calendars: it privately mirrors your free/busy time across all of them, and it turns your real availability into booking links.
Across Google and Microsoft. We mirror when you're busy — never what you're busy with.
Set it once. Then forget it.
Connect your Google and Microsoft calendars, draw which ones should mirror each other, and busyfold keeps your free/busy time in step — quietly, in the background.
-
Connect your calendars
Authorize the Google or Microsoft accounts busyfold should keep in sync. A calendar can provide availability, receive busy blocks, or do both.
-
Draw your sync connections
On the canvas, connect each source calendar to the calendars that should mirror it. Each calendar's role follows the connections you draw.
-
It protects every slot
When an event lands, busyfold writes a generic busy block across the calendars you chose — without copying the source event's details.
No copies, no clutter — just an honest “busy” wherever you need it.
See it work
Busy in, blocked out.
Wire your calendars together on a canvas, and busyfold mirrors busy time across them. The details are left out of the generated blocks, so connected calendars receive availability instead of source titles or notes.
Connect your calendars
Connect a source calendar to the destinations that should mirror it. Each calendar's role — source, destination, or both — follows the connections you draw.
Mix Google and Microsoft, work and personal — fan one calendar out to many, wired however your week actually works.
How your events appear
Same times, same shape; source titles, guests, and notes are left out of generated blocks.

What everyone else sees
No titles, no guests, no locations — just an honest unavailable.
Tune it to your liking
A few quiet settings decide how those blocks look and when they land.
What sync does
Everything it does, quietly.
Powerful where it counts, invisible the rest of the time.
-
Private by default
Destination calendars receive availability only. busyfold mirrors when you're busy, never the titles, guests, notes, or locations behind it.
-
Near-instant sync
On Google, push notifications refresh your blocks the moment a calendar changes. Microsoft calendars sync on a regular schedule, and sweeps catch anything missed.
-
Never double-booked
Sync skips real events and your own manual blocks, so generated blocks never pile on top of what's already there.
-
Tidy by default
Adjacent busy periods within your gap threshold merge into one clean block, so calendars stay readable.
-
Your window, your rules
Sync as far ahead as you like — from a single day up to 60 days on Pro.
-
Make it yours
Pick the title and colour busyfold paints on destination calendars, and optionally skip weekends.
Turn availability into booking links.
Create reusable meeting types or single-use links. Invitees pick a real open slot, busyfold checks your connected calendars and books the event on your Google or Microsoft host calendar.
Scheduling is included in Pro, with public booking pages, one-time links, and self-service manage links for every confirmed meeting.

How booking works
- Step 1
Create a booking type
Claim your @handle, then set duration, buffers, minimum notice, daily caps, and where you'll meet.
- Step 2
Share your link
Send a reusable page at app.busyfold.cc/b/yourhandle/intro-call, or a one-time link when a meeting needs tighter control.
- Step 3
They pick a real slot
busyfold checks your calendars, books a real event on Google or Microsoft, and sends a manage link for reschedule or cancel.
What booking does
Booking, without the back-and-forth.
Share a link, let invitees pick a real open slot, and let busyfold put it on your calendar — no email tag, no double bookings.
-
Reusable booking links
Publish meeting types on your public handle; share one link and take many bookings.
-
One-time links
Send a single-use link when a meeting needs tighter control; it can expire after it's booked.
-
Real availability
Slots honour your connected calendars, buffers, minimum notice, booking window, and daily caps before anyone can book.
-
Lands on your calendar
Every booking becomes a real event on your Google or Microsoft host calendar, with a Meet or Teams link attached.
-
Self-service changes
Each booking carries a manage link, so invitees reschedule or cancel without another email thread.
-
Timezone-aware
Invitees book in their own timezone; you always see slots in yours.

Compare
How busyfold compares.
busyfold is the rare tool that does both private free/busy sync and booking links — with a real free tier. Here’s an honest look, including where others lead.

Lowest paid tier per user, observed June 2026; some prices assume annual billing (monthly costs more) — always check each vendor’s site.
* Cal.com Teams is the entry paid tier; Cal.com is also free to self-host, if you run and maintain the servers yourself.
† busyfold Pro includes 5 calendars; add more in packs of 5 at $3 / mo each, up to 25 in total.
‡ Apple / iCloud has no OAuth calendar API, so these tools connect it over CalDAV with an Apple-ID app-specific password — clunkier and slower than Google or Microsoft.
§ busyfold’s near-instant updates use Google push notifications; Microsoft calendars sync on a regular schedule.
Native (Google / Outlook) means subscribing one calendar to the other with a secret iCal link: free, but one-way, refreshed only every ~12–24 hours, and the events don’t block your availability — so people scheduling with you still see you as free.
FAQ
Questions, folded out.
The short answers on sync, booking, privacy, and control — before you connect a single calendar.
Does busyfold see my event details?
busyfold needs OAuth access to the calendars you connect so it can sync them. It minimizes what it stores and republishes: destination calendars get a generic busy block, never source titles, guests, notes, locations, or links.
How do I sign up?
Sign in with your Google account. You can connect Microsoft (Outlook) calendars right after signing in — direct Microsoft sign-in is on the way.
How fast does it sync?
On Pro, Google calendars update almost instantly — push notifications refresh your blocks the moment a calendar changes. Microsoft calendars sync on a regular schedule, and the free plan is scheduled for both.
Which calendars can I connect?
Any Google or Microsoft (Outlook) calendars you authorize. A single account can act as both a source and a destination, and you can mix Google and Microsoft freely.
Will it double-book me or clutter my calendar?
No. busyfold won't write over real events or your own manual blocks, and it merges nearby busy periods into one clean block.
Can I customise the blocks it creates?
Yes — choose the title and colour busyfold paints on destination calendars, set how far ahead it syncs, merge nearby blocks, and optionally skip weekends.
Is scheduling free?
Calendar sync has a free tier (up to 2 calendars). Booking links are part of Pro, which also adds more calendars and near-instant Google sync.
What's the difference between a reusable link and a one-time link?
A reusable link is a meeting type on your public handle (app.busyfold.cc/b/yourhandle/intro-call) that people can book again and again. A one-time link is single-use — for when a meeting needs tighter control — and can expire once it's booked.
What happens when someone books a time?
busyfold checks your connected calendars, creates a real event on your Google or Microsoft host calendar (with a Google Meet or Microsoft Teams link if you chose one), and emails the invitee a manage link.
Can invitees reschedule or cancel themselves?
Yes. Every booking includes a manage link, so invitees reschedule or cancel without logging in or starting another email thread.
Sync quietly. Book effortlessly.
busyfold keeps your Google and Microsoft calendars in private sync, and turns your real availability into booking links. Set it once; it runs in the background.
Bookings become real calendar events. Your busy time stays mirrored everywhere else.
