The self-hosted SimplyBook.me 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 SimplyBook.me every month.
Stop renting SimplyBook.me.
SimplyBook.me Basic EUR 11.9/mo billed annually (free tier exists) Slotly is $99 once, runs on your own server, and never invoices you again.
SimplyBook.me prices by booking volume rather than by seat, bundling a set number of staff providers into one flat monthly fee per tier.
“SimplyBook.me uses booking-volume pricing rather than per-user pricing, with each plan including a set number of staff providers at a single flat monthly fee.”, their own page, read 2026-08-11
SimplyBook.me's free plan includes real booking capacity and app access, not just a stripped-down demo.
“Yes, SimplyBook.me offers a free plan that includes up to 50 bookings per month, 1 premium custom feature, basic email reminders, and access to the booking widget and client app.”, their own page
If you want online payments and deposits taken at booking without holding your own Stripe account, stay with SimplyBook.me — Slotly takes them by card only through your own Stripe account, when you switch card payments on; otherwise deposits are only tracked in admin.
What Slotly deliberately doesn't do is on its product page.
Why owning beats renting SimplyBook.me.
No monthly, per-seat or per-location fees. The license is perpetual.
It never lives in SimplyBook.me's cloud.
Records and users are limited by your hosting, not by a pricing tier.
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.
