A side-by-side editorial comparison of Easy!Appointments and Double — release velocity, themes, recent moves, and the top alternatives to consider.
Easy!Appointments makes CalDAV sync failures explain themselves.
Easy!Appointments ships slowly through alpha and beta pre-releases. The 1.6.0 cycle added Jitsi meeting links for appointments booked on the public page, a meeting-link field, and a dedicated Google Calendar integration section. The 1.6.1 pre-releases tighten input validation and make CalDAV sync usable on local networks, with failures explained on the calendar page.
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.

The scheduler is building out integrations (Google Calendar, CalDAV, Jitsi) and then hardening them so self-hosters can diagnose problems without reading logs. Cadence is slow, with months between pre-releases, and the 1.6.0 notes are repeated across three cuts.
A 1.6.1 stable release with the CalDAV and validation work is the likely next step; the entries don't show new integrations queued behind it.

Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
