🗓️ SlotBook
REPLACES CALENDLY for one price.
Your own booking page, without the subscription. Set the hours you work, create the kinds of appointments you offer — intro calls, consultations, sessions — and share one link. Visitors see only the times that are actually free, in their timezone, and book without creating an account.
$39 one-time. No subscription. Yours forever.

What it does
- Event types. Each kind of appointment gets its own duration, location or meeting link, buffers before and after, minimum notice, and an optional cap on bookings per day. Pause any type without deleting it.
- Your hours, your timezone. A weekly schedule plus date overrides — a day fully off, or custom hours for one date. Everything is stored and computed in your IANA timezone, daylight-saving correctly.
- Slots that are really free. The booking page computes open times from your schedule minus overrides, existing bookings and buffers. A slot that gets taken disappears; booking the same time twice is refused, never double-booked.
- Visitors book in their timezone. Your 9:00 AM is shown to a visitor across the country as their correct local time — including on daylight-saving changeover days.
- Confirmations + a calendar file. Both sides get a confirmation email, and every booking comes with a downloadable .ics calendar file with the exact time.
- A manage link with every booking. Your booker can cancel or reschedule from a private link in their confirmation — no account, no back-and-forth email. Cancelling frees the slot immediately, and the other side is emailed.
Product facts
NEW Beta Web
- Price: $39 one-time · Browser tool
- Version: 1.0.0 · Released 2026-11-09
- Verified platforms: Web
- System requirements: Web — any modern browser
- Privacy: Your schedule, event types and bookings are stored on CertSight scoped to your account; no other account can see them. Your public booking page shows only your display name, event types and free times — never your other bookings or bookers. A booker's manage link is stored only as a hash.
- Known limitations: One person's calendar in v1: no team or round-robin scheduling, no payment for bookings, no Google or Outlook calendar sync (bookings export as .ics calendar files), no reminder emails (confirmations are sent; the .ics file is the reminder path), and no built-in video calls (paste your own meeting link into the event type).
What SlotBook does not do — stated plainly
- No reminder emails. SlotBook sends confirmations, cancellations and reschedule notices — not timed reminders. The .ics calendar file is the reminder path: the booker's own calendar app reminds them.
- No payment for bookings. Booking a slot is free for your visitors; if you charge, you invoice separately.
- No calendar sync. SlotBook does not read your Google or Outlook calendar. Your SlotBook schedule is the source of truth here, and .ics export is how bookings reach your calendar.
- One person's calendar. No team or round-robin scheduling in this version, and no built-in video calls — paste your own meeting link into the event type.
- Not the AI Receptionist. CertSight's AI Receptionist answers calls and chats for a business. SlotBook is the simpler thing: your booking page, your hours, your clients.
