SyncThemCalendars gives you sync. CalendarPipe gives you sync you can program.
SyncThemCalendars is a solid, straightforward sync tool, priced by how many syncs you run — $3.99 a month for five, up to $17.99 for thirty-six. CalendarPipe takes a different angle: rules you write, so you can filter events, rewrite titles and set visibility per rule, on a free tier that never expires.

Where SyncThemCalendars falls short
SyncThemCalendarshas strengths, but here's what users run into.
No programmable rules
SyncThemCalendars offers rename and privacy controls, but you can't write conditional logic or transform events with code.
Per-sync pricing adds up
SyncThemCalendars charges by sync count — 5 syncs on Basic, 36 on Professional at $18/month. CalendarPipe Pro gives you unlimited syncs for $4/month.
Individual plans only
Published tiers are for individual users. If you need team features or multi-user billing, options may be limited.
No API or developer tools
SyncThemCalendars doesn't offer a REST API or integrations for automations and AI agents.
Why teams switch to CalendarPipe
Rules, not just toggles
Write JavaScript that filters, transforms, and routes events. Use the visual builder or plain English for simple cases. SyncThemCalendars gives you rename and privacy toggles — CalendarPipe gives you a programming language.
4x cheaper for unlimited syncs
CalendarPipe Pro is $4/month for unlimited sync rules. SyncThemCalendars Professional is $18/month for 36 syncs (pricing as of August 2026).
Free forever, with a matching trial
CalendarPipe's free plan never expires — 2 calendars, 1 sync rule. SyncThemCalendars only gives you a 14-day trial, then it's pay or leave. We match the trial length and let you stay free after.
Built for developers
A REST API and installable agent skills. Integrate calendar sync into your workflows and automations.

When SyncThemCalendars is the better choice
We'd rather you pick the right tool than the one we sell.
Your sync is already covered and working
SyncThemCalendars supports Google, Outlook, and Apple with rename and privacy controls. If that is your entire requirement and it runs today, moving to CalendarPipe mostly buys capability you may never use — programmable rules, ICS feeds, an API.
You want fewer choices, not more
CalendarPipe's rules are the point of the product, and even the visual builder assumes you want to shape events. SyncThemCalendars keeps the decisions down to rename and privacy. For a simple sync, fewer knobs is a real advantage.
