What you give up vs Calendly

  • Focused on group availability polling rather than one-on-one booking pages, so it does not replace Calendly's personal booking links.
  • No direct calendar-availability checking or two-way calendar sync to auto-block busy times.
  • No built-in payment collection or paid-appointment support.
  • Requires PostgreSQL and SMTP configuration to self-host; not a single-binary deploy.

What you gain

  • • Full data ownership — self-host Rallly on your own infrastructure.
  • • No per-seat SaaS bill (Calendly: per-seat fees for multiple event types).
  • • Open-source code you can audit and extend (AGPL-3.0).
