Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Agenda
- Library only — no UI for managing or viewing scheduled jobs without additional tooling
- Requires MongoDB; not suitable for simple SQLite/Postgres-only stacks
- No native support for distributed locking at high scale
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
Bottom line
Both are a similar lift to self-host; choose Agenda for the larger community and ecosystem. Agenda has seen more recent development. Open each guide below for deploy steps and the full feature gap.
