Comparison
Free appointment scheduling software — the honest comparison
Most 'free' scheduling tools have asterisks. Here's what each one actually gives you for free, and where they push you to pay.

Almost every scheduling tool calls itself "free" — but the asterisks differ. Common patterns:
- Free for one event type only.
- Free, but the booking page has the vendor's branding watermark.
- Free, but you can't send reminder emails.
- Free for 14 days, then auto-converts to paid.
- Free, but bookings cap at N per month.
That's not necessarily bad — vendors need to make money. But it makes comparing "free" plans across tools confusing on purpose. Here's what each actually offers in 2026.
Calendly (free plan)
- One active event type at a time.
- Booking page has "Powered by Calendly" branding.
- No removing branding, no team scheduling, no Workflows on free.
- Google and Outlook calendar sync included.
- Best for: a single recurring event type with no customization needs.
Cal.com (hosted free plan)
- Unlimited event types and bookings.
- Booking page has "Powered by Cal.com" branding.
- Most integrations free; some advanced features (analytics, teams, routing) on paid plans.
- Multi-calendar support: Google, Outlook, iCloud, CalDAV.
- Best for: technical users comfortable with workspace-style configuration.
SimplyBook.me (free plan)
- Up to 50 bookings/month.
- One custom feature included; additional features are paid à la carte.
- Best for: very low-volume service providers willing to manage feature add-ons.

- Built into Google Calendar; create a booking page directly in your calendar.
- Limited customization; no embed widget for your own site without iframe hacks.
- Best for: someone happy to share a Google-hosted booking page link.
- See our dedicated comparison: Google Calendar booking page vs website widget.
circleit (free, forever, for individuals)
- Unlimited event types and bookings.
- Unlimited installs across as many sites as you want.
- No required branding watermark (we ask, we never force).
- One-line embed: copy, paste, done.
- Google Calendar at launch; Outlook/iCloud on the roadmap.
- Best for: small business owners who want the simplest possible booking widget on their existing website.
How to pick
Honest decision tree:
- If you need Outlook calendar sync today: Calendly free or Cal.com hosted.
- If you want self-hosting and full control: Cal.com self-hosted.
- If you want built-in payment collection now: Calendly paid (or wait for circleit's v1).
- If you're a non-technical small business owner who wants the simplest possible widget on your existing site: circleit.
- If you're happy sending people a Google-hosted booking link (not embedded on your own site): Google Calendar appointment schedule.
No "best" — just fits. Pick the one whose tradeoffs match what you actually need.
