Amelia vs Stalwart
A side-by-side editorial comparison of Amelia and Stalwart — release velocity, themes, recent moves, and the top alternatives to consider.
Amelia vs Stalwart: at a glance
What is Amelia?
Amelia keeps sanding down booking friction — sync, staffing, and now pre-booking intake.
Amelia is a mature WordPress appointment and event booking plugin shipping on a roughly monthly point-release cadence. Recent work concentrates on the friction points of scheduling: calendar sync across Google and Outlook, employee availability rules, and payment flexibility. The newest move extends the product past scheduling into structured intake, letting businesses collect details before a booking is confirmed.
What is Stalwart?
Stalwart keeps hardening its JMAP stack while moving early on emerging email-auth standards.
Stalwart is an all-in-one mail and collaboration server — JMAP, IMAP, SMTP, CalDAV and OIDC in one binary — shipping point releases every week or two. The last five releases pair an aggressive JMAP conformance drive with steady expansion of standards coverage. It reads as a project optimizing for correctness and completeness rather than new product surface.

Amelia keeps sanding down booking friction — sync, staffing, and now pre-booking intake.
◆ Current state
Amelia is a mature WordPress appointment and event booking plugin shipping on a roughly monthly point-release cadence. Recent work concentrates on the friction points of scheduling: calendar sync across Google and Outlook, employee availability rules, and payment flexibility. The newest move extends the product past scheduling into structured intake, letting businesses collect details before a booking is confirmed.
◆ Where it's heading
The arc is steady consolidation rather than reinvention — each release closes a gap in the booking-to-payment loop instead of opening a new category. Integrations (IvyForms for intake, Outlook and Google calendar sync) are becoming the growth surface, positioning Amelia as the scheduling hub other WordPress tools plug into. Early AI admin tooling ('Angie') has appeared but stays peripheral to the core booking flow.
◆ Prediction
Expect the next releases to keep deepening integrations and calendar management, with the IvyForms intake pattern likely extended to more form and CRM tools. Whether the AI admin tooling grows into anything customer-facing is unclear from these entries.
Stalwart
5.0COMMS
Stalwart keeps hardening its JMAP stack while moving early on emerging email-auth standards.
◆ Current state
Stalwart is an all-in-one mail and collaboration server — JMAP, IMAP, SMTP, CalDAV and OIDC in one binary — shipping point releases every week or two. The last five releases pair an aggressive JMAP conformance drive with steady expansion of standards coverage. It reads as a project optimizing for correctness and completeness rather than new product surface.
◆ Where it's heading
Two arcs run in parallel: closing JMAP spec gaps to pass conformance suites, and adopting fresh email-authentication standards (DKIM2, DMARCbis, VAPID web push) ahead of most competitors. Platform reach (FreeBSD) and at-rest encryption round out a hardening push. The direction is a standards-maximal, production-grade mail server, not a feature-led one.
◆ Prediction
Expect more 0.16.x point releases that finish the JMAP conformance work and stabilize the new DKIM2, DMARCbis and web-push paths, with fixes continuing to outnumber features.
