A side-by-side editorial comparison of Easy!Appointments and Monica — release velocity, themes, recent moves, and the top alternatives to consider.
Easy!Appointments 1.6 lands video conferencing, GDPR tools, and a serious security overhaul across its CalDAV and booking stack.
Easy!Appointments, an open-source self-hosted scheduler, is shipping its 1.6 major version through a long pre-release cycle that has introduced Jitsi and Google Meet integration, CAPTCHA and ALTCHA anti-abuse protection, GDPR features, and a rebuilt CalDAV synchronization stack. The 1.6.1 security hardening pre-release then landed a concentrated batch of serious vulnerability fixes: LDAP injection in directory search, SSRF in CalDAV URL handling, cross-account appointment takeover, provider credential exposure to secretary accounts, and CAPTCHA bypass — a set that suggests the expanded surface area of 1.6.0 brought corresponding security debt.
v5 'Chandler' rewrite stalled in beta — newest release is over a year old
Monica's entire recent history is the v5.0.0 'Chandler' rewrite, a ground-up rebuild first released in June 2023 and progressing through five betas. The latest, beta.5 (April 2025), added a Typesense search connector and Keycloak/Kanidm SSO among many fixes. But it is now the newest entry by more than a year, with no stable v5 or further beta since.

The 1.6 release line is expanding Easy!Appointments from a simple booking page into a more complete scheduling platform: video conferencing links, richer calendar sync, GDPR compliance tooling, and hardened multi-provider access controls all move it closer to commercial alternatives. The security work in 1.6.1-beta.1 is as important as the features — self-hosted deployments that serve real customer data need these fixes before anyone should run 1.6 in production.
A stable 1.6.1 release is the next step, clearing the pre-release label once the security fixes are confirmed across the beta testing community. After that, the CalDAV and video conferencing integrations will likely expand — CalDAV push notifications or two-way Google Calendar sync are the natural follow-ons.

But it is now the newest entry by more than a year, with no stable v5 or further beta since.
The arc is a long, slowing beta cycle that appears to have stalled. Early betas shipped broad feature sets; later ones narrowed to incremental fixes and self-hoster conveniences (SSO, search backends, DAV sync). The gap since April 2025 is the dominant signal: momentum on the rewrite has visibly stalled and a stable v5 has not materialized.
Hard to call given the year-plus silence — either a long-delayed v5 stable cut or continued dormancy. The entries don't support confidence either way; the absence of recent activity is itself the most telling data point.
