Where LineMerge fits
Scheduling tools split into two camps: ones that sync calendars to each other, and ones that publish a booking page. If you run more than one line you currently need both.
| Capability | Calendar-sync tools | Booking-page tools | LineMerge |
|---|---|---|---|
| Merge several calendar accounts into one view | Yes — that's the product | Usually one primary calendar, plus conflict checks | Yes |
| Public booking page with slot rules | No | Yes — that's the product | Yes |
| Per-calendar public/private controls | Varies | Not the model | Yes — private calendars show busy time only, to everyone but you |
| Source tag on every busy block | Sometimes | No | Yes |
| Calendars with no server API (iCloud, Exchange) | Rarely | No | Bridged from the phone |
| Merged availability as a subscribable feed | Sometimes | No | Yes |
| Several businesses on one bill, each with its own page | No | Rarely | Yes — up to 10 on Team |
| Questions, screening and routing on the booking page | No | Yes | Yes |
| Group sessions and weekly repeats | No | Yes | Yes |
| Webhooks / Zapier, insights, client records | Rarely | Yes | Yes |
| One subscription, one bill | Second tool | Second tool | One |
Compared by capability category rather than by naming a competitor's feature list, because those change often and a stale comparison table is worse than none. Categories are representative, not exhaustive — check any specific tool's current docs.
By name
Booking-page tools include Calendly, Cal.com, SavvyCal, Acuity, Zoho Bookings and Microsoft Bookings. Calendar-sync tools include OneCal, CalendarBridge, SyncGene and Reclaim's calendar sync. LineMerge is an alternative to running one from each list: it merges every calendar you own into one availability and publishes the booking page itself.
Both kinds of tool are good at their half. LineMerge exists for the person who needs both halves and would rather run one thing.
What the merge looks like
Every busy block shows which line it came from. The booking page never shows any of this — it only offers the gaps.
The honest version
If you have one calendar and want a booking link, a booking-page tool is a fine answer and probably cheaper in effort. LineMerge earns its place when you genuinely run more than one line and the merge — plus keeping the private one private — is the hard part.
That's the whole bet: one tool instead of two, with per-calendar privacy that starts at "only me" and stays wherever you set it.
