Easy!AppointmentsEveryone points here for open source; it has providers and reminders, but no built-in payments or class workflow.
Picktime FreeThe free plan handles classes and bookings, but reminders and custom intake fields are paid.
Reservio FreeFree means 40 bookings a month and no calendar sync; that is a demo-sized business, not a replacement.

Acuity Scheduling: People pay because a booking tool must never double-book them, leak private events, or send the wrong time to a client. If none of that applies to you, any pick above saves $240 a year.
Is there a free alternative to Acuity Scheduling?
Yes: Appointy Free, Setmore Free, Square Appointments Free and 1 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Acuity Scheduling?
Our verdict is KINDA. The visible appointment scheduling loop is buildable, but a credible replacement needs more than the first screen. Acuity Scheduling earns its keep through OAuth, calendar reliability, so expect a weekend or multi-day build and a narrower personal scope. If you'd rather build, the exact one-shot prompt is free at canivibecodeit.com/acuity-scheduling.
