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
vimcal
Pros
Speed- and keyboard-shortcut-focused design aimed at cutting time spent on scheduling
Unifies multiple Google and Outlook calendars (work and personal) into a single view
Purpose-built EA tier with calendar audits, account handoff, and multi-time-zone tools for people scheduling on someone else's behalf
Free trial with no credit card required
Genuine free tier (iOS-only) in addition to paid plans, so users can try core functionality at no cost
Cons
The free tier is limited to iOS only — desktop and full multi-account features require a paid plan
Enterprise and EA Enterprise tiers use custom/contact-sales pricing with no published rate
The jump from the $20/mo Standard plan to the $75/mo EA Scheduling tier is steep for users who only need a subset of EA features
Publicly documented integrations are limited to Google Calendar and Microsoft Outlook, with no confirmed native integrations for tools like Zoom or Slack on the marketing site
