The self-hosted SimplyBook.me alternative
Slotly — Appointment & Booking System (PHP + MySQL, Self-Hosted) — Self-hosted appointment booking engineered so it can't double-book. Own it once, run it on your own server, and stop paying SimplyBook.me every month.
SimplyBook.me Basic EUR 11.9/mo billed annually (free tier exists) Slotly — Appointment & Booking System (PHP + MySQL, Self-Hosted) is $99.00 once, runs on your own server, and never invoices you again.
How SimplyBook.me pricing grows with you
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
What SimplyBook.me does that we don't
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
Who should stay with SimplyBook.me
If you need to collect online payments and deposits directly at booking, stay with SimplyBook.me — Slotly does not process card payments, deposits are only tracked in admin. Full honest limitations are on the product page.
Why owning beats renting SimplyBook.me
- One payment. No monthly, per-seat, or per-location fees — the license is perpetual.
- Your data stays on your server. It never lives in SimplyBook.me's cloud.
- No plan ceilings. Records and users are limited by your hosting, not a pricing tier.
- It keeps working if the vendor doesn't. Self-hosted software can't be sunset or price-hiked out from under you.
Fair trade-offs: you host it, back it up, and apply updates yourself — see the product page for honest limitations, and the full Slotly — Appointment & Booking System (PHP + MySQL, Self-Hosted) vs SimplyBook.me comparison.
