FreeBusy vs OnceHub (2026): which should you pick?

Pick FreeBusy if

• Fits if you keep work, home and client calendars and want one free-time view
• Works for recruiters or sales teams that send availability links

Look elsewhere if

• Skip it if you need team scheduling on the free plan, as Personal is for individuals only
• Pricey if you add a team: Business is $10 per registered user a month
• Watch out: the comparison does not show which plan includes each feature
• Watch out: SSO, BYOK and VPN options are listed but not tied to a plan, and Enterprise is quoted on request

Pick OnceHub if

• Fits if your sales or service team qualifies leads before anyone gets a slot
• Works for advisors, coaches and clinics whose clients book by phone as well as online

Look elsewhere if

• Pricey if you only want round robin, which starts on Route at $19 a seat a month billed annually
• Tight if you're staying free and need a second calendar or a second booking link
• Pricey if you want chatbots, which need Engage at $39 a seat, or SSO and HIPAA, a $5-a-seat add-on on top
• Watch out: text notifications need SMS credits, plans include only 1 to 3 phone numbers, and extras are $4 a month
• Not for you if you want a phone app, as it's web and a browser extension only
