Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Baïkal
- No web-based calendar or scheduling UI for end users; requires a CalDAV client app
- No public booking page or availability-sharing feature comparable to Calendly
- Development activity has slowed; some sabre/dav edge cases may go unpatched
- HTTPS and reverse-proxy setup is manual and not guided
QloApps
- Scope is hotel-specific; not a general-purpose appointment scheduler
- Channel manager integrations (OTA sync) are limited compared to commercial PMS solutions
- Mobile app for guests/staff is absent out of the box
- PrestaShop heritage makes theming and customisation non-trivial
Bottom line
Choose Baïkal if you want the lower-effort setup; choose QloApps for the larger community and ecosystem. Baïkal has seen more recent development. Open each guide below for deploy steps and the full feature gap.
