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.
Authorize the Google or Microsoft accounts busyfold should keep in sync. A calendar can provide availability, receive busy blocks, or do both.
On the canvas, connect each source calendar to the calendars that should mirror it. Each calendar's role follows the connections you draw.
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
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 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.
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.
A few quiet settings decide how those blocks look and when they land.
What sync does
Powerful where it counts, invisible the rest of the time.
Destination calendars receive availability only. busyfold mirrors when you're busy, never the titles, guests, notes, or locations behind it.
Push notifications refresh your blocks the moment a calendar changes — on both Google and Microsoft (Pro). Sweeps still catch anything missed.
Sync skips real events and your own manual blocks, so generated blocks never pile on top of what's already there.
Adjacent busy periods within your gap threshold merge into one clean block, so calendars stay readable.
Sync as far ahead as you like — from a single day up to 60 days on Pro.
Pick the title and colour busyfold paints on destination calendars, and optionally skip weekends.
Connect any MCP-compatible AI assistant to your availability via a first-party OAuth server — agents see busy/free only, never your event details.
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 starts on the free plan with one basic booking page. Pro adds a custom handle, unlimited booking types, one-time links, and self-service reschedule and cancel links for every confirmed meeting.

How booking works
Claim your @handle, then set duration, buffers, minimum notice, daily caps, and where you'll meet.
Send a reusable page at app.busyfold.cc/b/yourhandle/intro-call, or a one-time link when a meeting needs tighter control.
busyfold checks your calendars, books a real event on Google or Microsoft, and sends a manage link for reschedule or cancel.
What booking does
Share a link, let invitees pick a real open slot, and let busyfold put it on your calendar — no email tag, no double bookings.
Publish meeting types on your public handle; share one link and take many bookings.
Send a single-use link when a meeting needs tighter control; it can expire after it's booked.
Slots honour your connected calendars, buffers, minimum notice, booking window, and daily caps before anyone can book.
Every booking becomes a real event on your Google or Microsoft host calendar, with a Meet or Teams link attached.
Each booking carries a manage link, so invitees reschedule or cancel without another email thread.
Invitees book in their own timezone; you always see slots in yours.
Team scheduling
On Pro, invite collaborators and bring their Google or Microsoft calendar in as a booking host or an availability source — all under a shared team handle. Each team starts with 3 contributed calendar slots and scales with $10 add-on packs (+3 team slots each); booking types can rotate across a pool of hosts (round-robin) or require the whole panel to attend (collective), giving teams real flexibility without over-promising strict per-host schedules.
Bring a collaborator's Google or Microsoft calendar in as the booking host — their availability drives the slots, the event lands on their calendar.
Connect a teammate's calendar as an availability source, so slots only appear when both of you are free.
Publish booking pages under a shared team handle with a single name and brand identity visible to invitees.
Let an assistant run booking pages that land on an executive's calendar — the assistant manages the page, the exec hosts the meeting.
Connect any MCP-compatible AI system — such as Claude — to busyfold. It checks when you're free and books meetings for you, and it never sees a single event title, guest, or note. Your assistant gets your availability; the LLM never gets your private life.
It's what makes a privacy-preserving personal assistant possible: point Hermes, OpenClaw, or NanoClaw at busyfold and it can run your whole calendar — every request hands back only your free/busy times and open slots, never the private details behind them.
Agent access is a Pro feature. Your assistant connects once over OAuth 2.1 (PKCE) — straight to busyfold, with no third-party broker and no tokens to paste — and you can revoke it at any time.
Find 30 minutes with Priya next week and book it.

The privacy boundary
busyfold answers every agent request with times — never the contents of your calendar. The split is enforced server-side, on every single call.
Same guarantee as calendar sync: agents get the exact busy/free signal busyfold mirrors — and nothing more.

Compare
busyfold puts private free/busy sync and booking links in one simple Pro plan, with add-ons when you need more capacity — not a per-seat team tier just to schedule together. Here’s an honest look, including where others lead.
Do the math
Pick a team size and the section shows the real unit first: people covered. Calendars and booking slots sit beside it as capacity, then the price comparison follows.

busyfold does private sync AND booking — one subscription, not two.
busyfold = flat Pro ($8/mo, or $80/yr — 2 months free) plus add-on packs ($10/mo, or $100/yr each) — each pack adds 3 more team booking slots (your 5 personal calendars are included and stay flat), so team capacity scales as far as you need; collaborators contribute calendars at no extra charge. Annual figures bill the per-seat rival at 12× its $16/seat/mo annual rate — a real team round-robin tier from the comparison table below (others run $12–$15/seat), verified June 2026.

Team scheduling is where busyfold’s value shows most: round-robin and collective booking types are included in Pro at $8 / mo — for up to 3 hosts, then $10 / mo per +3 — with no per-seat fees. Rivals charge per seat for the same — Calendly round-robin needs the Teams plan ($16 / seat / mo on annual billing, $20 monthly), Cal.com needs Teams ($12 / seat / mo), and Reclaim round-robin needs the Business plan (~$15 / seat / mo). A 9-host team runs roughly $108–$144 / mo there, versus $28 / mo on busyfold (Pro + two $10 packs). Calendly’s collective type is one tier down on Standard ($10 / seat); OneCal includes collective on Starter ($5 / seat) but documents no round-robin; Cal.com’s team features are also free if you self-host.
* Cal.com Teams is the entry paid tier; Cal.com is also free to self-host, if you run and maintain the servers yourself, which carries additional costs.
† busyfold Pro is $8 / mo and includes 5 personal calendars plus a 3-slot team space; each add-on pack ($10 / mo) adds 3 more team slots, so team capacity scales as high as your team needs.
‡ 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.
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.
§ busyfold’s MCP server (Pro) lets any MCP-compatible AI assistant read your busy/free availability via OAuth 2.1 PKCE. Event details are never exposed. Reclaim.ai has community-built MCP servers but no official one.
¶ Webhook notifications for booking events fire when a meeting is created, rescheduled, or cancelled. Calendly requires a Standard plan or above; Reclaim requires a Business plan or above. Cal.com includes webhooks on all plans, including free.
FAQ
The short answers on sync, booking, privacy, and control — before you connect a single calendar.
busyfold needs OAuth access to the calendars you connect so it can sync them. While the access allows it to read the content of your events, it does not do so, nor does it store any of the information contained therein. Destination calendars only get a generic busy block, never source titles, guests, notes, locations, links or any other information.
Sign in with your Google account. You can connect Microsoft (Outlook) calendars right after signing in — direct Microsoft sign-in is on the way.
On Pro, both Google and Microsoft calendars update almost instantly — push notifications refresh your blocks the moment a calendar changes. The free plan uses scheduled sync for both.
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.
No. busyfold won't write over real events or your own manual blocks, and it merges nearby busy periods into one clean block.
Yes, as a Pro subscriber! Choose the title and colour busyfold paints on destination calendars, set how far ahead it syncs, merge nearby blocks, and optionally skip weekends.
Partly. busyfold Free includes private sync for up to 2 calendars and one basic booking link — a single reusable booking type on a busyfold page. A custom handle, unlimited booking types, one-time links, booking guardrails, and team scheduling are part of Pro, which also adds more calendars and near-instant sync.
A reusable link is a meeting type on your public handle (e.g. app.busyfold.cc/b/johnny/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.
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.
Yes. Every booking includes a manage link, so invitees reschedule or cancel without logging in or starting another email thread.
No. The MCP server gives AI agents read-only access to your availability — the same busy/free signal as calendar sync. Event titles, attendees, notes, locations, and all other details are never shared with agents. MCP access is available on the Pro plan.
Connect Claude or any MCP-compatible assistant to busyfold's first-party MCP server. It authorizes once over OAuth 2.1 (PKCE) — straight to busyfold, with no third-party broker and no tokens to paste — and can then check your free/busy times, find open slots, and create, reschedule, or cancel bookings on your behalf. It only ever receives times, never your event details, and you can revoke its access at any time. Agent access is a Pro feature.
Yes. One busyfold Pro subscription lets you create a team with 3 calendar slots, then fill those slots with your own calendars or invite collaborators to bring theirs. Team booking pages publish under a shared handle, and add-on packs add 3 more team slots each — your personal calendar allowance stays the same.
Yes. Round-robin and collective team booking types are included in busyfold Pro — no separate team tier and no per-seat host pricing. That cost difference gets large fast: a small round-robin pool stays one flat busyfold subscription (Pro, plus a $10 add-on pack per 3 extra hosts), while per-seat schedulers charge again for every host in the pool.
Round-robin rotates each new booking across a pool of team hosts — exactly one host runs each meeting, with availability drawn from anyone in the pool who is free. Collective scheduling requires every selected host to attend the same meeting, with availability drawn from the times everyone is free. What isn't there yet: capacity or group events with many invitee seats, and separate per-host schedules; a booking type shares one schedule timezone across the pool.
Zoom suport is one of the top requested features and is planned for later in 2026.
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.
