The self-hosted Acuity Scheduling alternative

Slotly: Self-hosted appointment booking that refuses a second booking for a slot already taken, even when two people try at the same moment. Own it once, run it on your own server, and stop paying Acuity Scheduling every month.

How we counted: Flat per-account Starter tier; annual billing saves 20%.

How Acuity Scheduling pricing grows

Acuity Scheduling's plans are tiered by how many staff or location calendars you need, scaling from a single calendar on Starter up to many more on higher tiers.

What Acuity Scheduling does that we don't

Acuity Scheduling puts its customer service on every plan rather than reserving it for the upper tiers.

Who should stay with Acuity Scheduling

If you need two-way calendar sync with Google Calendar, Outlook, or iCloud, stay with Acuity Scheduling — Slotly has no calendar sync and only knows about bookings made inside itself.

What Slotly deliberately doesn't do is on its product page.

Why owning beats renting Acuity Scheduling.

One payment

No monthly, per-seat or per-location fees. The license is perpetual.

Your data stays on your server

It never lives in Acuity Scheduling's cloud.

No plan ceilings

Records and users are limited by your hosting, not by a pricing tier.

It keeps working if the vendor doesn't

Self-hosted software can't be sunset or repriced out from under you.

The fair trade-offs: you host it, back it up and apply updates yourself. See the product page for its limits, and the full Slotly vs renting comparison.

Questions about moving off Acuity Scheduling.

Does it take payment online?
Yes, if you switch on card payments with your own Stripe account: a service can take its deposit, or the full price, by card while the customer books, on Stripe's own page, and the money goes from Stripe to your bank. Slotly never sees the card and takes no cut. Without card payments, deposits are quoted and tracked in admin, and your own payment link (Stripe, PayPal or any page) is shown beside the amount due.
What do automatic reminders need?
One cron line enables them. Email goes through SMTP or PHP mail(), and texts, for customers who ask, through your own SMS gateway.
Can I run group classes?
Yes — set a capacity and multiple people can book the same slot.
MySQL or SQLite?
Either — MySQL for shared hosting, SQLite for a local trial.
