Bookslot — Self-Hosted Scheduling & Booking Page

$39

Self-hosted Calendly alternative. Pay once, book forever.

Bookslot is the Calendly you actually own: a self-hosted booking page on your own domain. Calendly Standard is $10/user/month — $360 over three years — for a calendar grid and an email. Bookslot is $39 once. Visitors pick a time in their own timezone on a clean dark-mode page and get a confirmation email with a calendar invite; you manage everything from a password-protected admin panel.

For coaches, consultants, barbers, and freelancers who are done renting their booking link.

  • Event types with duration, description, color, buffers before/after, minimum notice, and max days ahead — each with its own public link like /book/intro-call

  • Weekly availability editor plus one-off blocked dates and times

  • Timezone-correct slot math: stored in UTC, computed in your timezone (DST-safe and unit-tested), displayed in the visitor's

  • Double-booking protection re-checked inside a SQLite transaction

  • Email confirmations with .ics calendar attachment, owner notifications, cancellation emails (BYO SMTP, optional)

  • Private tokenized cancel/reschedule link in every confirmation

  • Admin view of upcoming and past bookings; cancel with a reason

  • Zero telemetry, single SQLite file, trivial to back up

Runs as a Windows desktop app or on a $5 VPS (Docker included).
