Element X Android vs Stalwart
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 vs Stalwart: at a glance
What is Element X Android?
Element X Android ships steady, feature-rich Matrix-client releases on a near-weekly beat.
The feed is genuine GitHub release notes for the Matrix client, and the cadence is brisk and substantive: message forwarding to multiple rooms, image crop/rotate before sending, custom notification sounds, avatar previews, and a security fix for an OIDC callback crash. Feature flags for shipped capabilities are being removed.
What is Stalwart?
Stalwart keeps hardening its mail server with standards conformance and at-rest encryption.
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.
Element X Android vs Stalwart: editorial side-by-side
Element X Android
5.0COMMS
Element X Android ships steady, feature-rich Matrix-client releases on a near-weekly beat.
◆ Current state
The feed is genuine GitHub release notes for the Matrix client, and the cadence is brisk and substantive: message forwarding to multiple rooms, image crop/rotate before sending, custom notification sounds, avatar previews, and a security fix for an OIDC callback crash. Feature flags for shipped capabilities are being removed.
◆ Where it's heading
Element X is in steady maturation — closing UX gaps against mainstream messengers (media editing, notifications, forwarding), hardening security, and promoting flagged features to default-on. Calling (Element Call) work recurs across releases.
◆ Prediction
Expect continued UX-parity and calling improvements with periodic security patches, and more feature flags retired as capabilities stabilize.
Stalwart
5.0COMMS
Stalwart keeps hardening its mail server with standards conformance and at-rest encryption.
◆ Current state
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.
◆ Where it's heading
The work points toward production maturity: closing JMAP spec gaps, adding high-availability primitives (Redis Sentinel coordination), and tightening TLS, DANE, and encryption. Stalwart is positioning itself as a standards-faithful, deployable alternative to legacy mail stacks rather than chasing new user-facing features.
◆ Prediction
Expect continued point releases that finish protocol conformance and expand operational features—high-availability backends, certificate handling, and encryption options—rather than a major feature pivot.
