Pros & Cons
DAViCal
Pros
Completely free and open source under the GPLv2 license
Full control and ownership over calendar and contact data via self-hosting
Implements open CalDAV/CardDAV standards, ensuring broad client compatibility
Mature, long-standing project with a stable feature set for group calendaring
Cons
Requires manual setup and maintenance of a PHP and PostgreSQL server stack
Administrative interface is functional but visually dated compared to newer alternatives
No official commercial support channel; relies on community and third-party providers
Less actively developed than some newer self-hosted alternatives like Baikal or Nextcloud
Akiflow
Pros
Consolidates tasks and calendars from many different tools into one planning workflow
Time-blocking approach encourages realistic daily scheduling rather than open-ended to-do lists
Available across web, desktop (Mac/Windows), and mobile (iOS/Android) with sync
Backed by Y Combinator with an active product development pace
Cons
No free perpetual plan — only a 7-day free trial before requiring payment
Monthly pricing ($34/month) is relatively high compared with some task-management competitors
Small team size may mean slower feature rollout or support response versus larger productivity vendors
