Stalwart vs Element: at a glance
What is Stalwart?
Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.
Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.
What is Element?
Element rebuilds its timeline with MVVM architecture while cutting legacy OS support in v1.12.28.
Element, the open-source Matrix messaging client, ships on a stable two-week release cadence and is currently at v1.12.28. The project is mid-way through a multi-part Timeline MVVM refactor (parts 1 and 2 in v1.12.26 and v1.12.27), restructuring the core room timeline component. The v1.12.28 release raises the minimum glibc requirement to 2.34, ending support for Debian bullseye and Ubuntu releases older than 22.04.

Stalwart
6.3COMMS
Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.
◆ Current state
Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.
◆ Where it's heading
Stalwart is building toward parity with commercial enterprise mail servers on identity federation and provisioning (SCIM v2, VAPID for web push, DMARCbis/DKIM2 already landed). The pace of RFC implementation is unusually aggressive for an open-source project; the combination of JMAP, CalDAV, IMAP UIDONLY/UIDBATCHES, and SCIM v2 positions it as a viable self-hosted alternative for organizations that need standards compliance without vendor lock-in.
◆ Prediction
WebAuthn/passkey-based authentication and improved multi-tenant administration tooling are the most likely next capability additions, given the current trajectory toward enterprise identity management.
Element
5.0COMMS
Element rebuilds its timeline with MVVM architecture while cutting legacy OS support in v1.12.28.
◆ Current state
Element, the open-source Matrix messaging client, ships on a stable two-week release cadence and is currently at v1.12.28. The project is mid-way through a multi-part Timeline MVVM refactor (parts 1 and 2 in v1.12.26 and v1.12.27), restructuring the core room timeline component. The v1.12.28 release raises the minimum glibc requirement to 2.34, ending support for Debian bullseye and Ubuntu releases older than 22.04.
◆ Where it's heading
The Timeline MVVM series is the defining architectural investment of this window — replacing the legacy timeline rendering with a proper view-model separation. This is foundational work that typically precedes faster feature delivery on the timeline surface (thread UX, call integration, richer message types). Parallel work promoting Custom Themes to devtools and updating bundle configurations signals cleanup of the extension and theming surface alongside the core refactor.
◆ Prediction
A Timeline MVVM part 3 or final integration is the immediate next step; once complete, expect improved thread UX or voice/video call timeline integration as the first beneficiaries of the new architecture.
