Superhuman rebuilt its mobile apps and wired every inbox into AI assistants — the email client is becoming a suite.
A side-by-side editorial comparison of Element X Android and Stalwart — release velocity, themes, recent moves, and the top alternatives to consider.
Element X Android ships steady maintenance releases; no directional move in the last 90 days
Element X Android ships on an approximately weekly cadence, with releases dominated by bug fixes, translation syncs, and infrastructure work. Visible new capabilities over the last three months are genuinely incremental: multi-answer polls, user status indicators, live location share push notifications, and a richer call participant list. The product's identity remains an open-source Matrix client focused on protocol compliance and enterprise configurability rather than consumer feature parity with Signal or WhatsApp.
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.

The project is building toward enterprise-ready deployment, not consumer growth. The enforce_element_pro FOSS flag, wellknown-based enterprise configuration, and notification reliability fixes all point to an MSC implementation-first strategy aimed at organizations self-hosting Matrix homeservers. There is no visible consumer-side push in this changelog — no major UX overhaul, no onboarding rethink, no third-party integration surface.
The next meaningful change is likely completion of pending MSC protocol work — the live location share notification implementation (MSC4505) and session verification reliability fixes suggest the team is working through a protocol backlog. A user-visible capability push is not visible from the current trajectory.

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.
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.
