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 grinds through calls, accessibility and enterprise auth hooks.
Element X Android ships a versioned release roughly every two weeks, each pairing one small feature with a long tail of fixes. The newest adds active call timeline rendering; before it came scroll-to-unread, forwarding a message to several rooms, and well-known parsing for a custom recovery passphrase. A sustained accessibility push runs through the July releases — TalkBack reading order, screen reader labels on the composer and search, focus indicators on PIN entry.
What is Stalwart?
Stalwart is shipping email's next-generation auth stack while the specs are still in draft.
Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.
Element X Android vs Stalwart: editorial side-by-side
Element X Android
5.0COMMS
Element X Android grinds through calls, accessibility and enterprise auth hooks.
◆ Current state
Element X Android ships a versioned release roughly every two weeks, each pairing one small feature with a long tail of fixes. The newest adds active call timeline rendering; before it came scroll-to-unread, forwarding a message to several rooms, and well-known parsing for a custom recovery passphrase. A sustained accessibility push runs through the July releases — TalkBack reading order, screen reader labels on the composer and search, focus indicators on PIN entry.
◆ Where it's heading
The work splits between finishing the basics the Element X rewrite left out and adding seams for managed deployments: MDM-configured homeservers, homeserver-controlled encryption in Element Pro, custom recovery passphrase parsing, external modules extending developer settings. Calls are the one feature area getting real investment. This is a client being made complete rather than pointed somewhere new.
◆ Prediction
Calls look like the next feature beat given the active call timeline work, with Element Pro configuration hooks continuing to arrive as small per-release additions.
Stalwart
5.0COMMS
Stalwart is shipping email's next-generation auth stack while the specs are still in draft.
◆ Current state
Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.
◆ Where it's heading
The project is building toward being the reference implementation of the modern mail stack — JMAP first, with the classic protocols held at parity rather than left behind. The fix lists have shifted in character over these eight releases: less "feature does not work", more "spec detail is wrong", which is what a codebase looks like as it converges on conformance. Security and multi-tenancy fixes keep appearing alongside the protocol work, indicating real deployments are exercising the newer subsystems.
◆ Prediction
The next releases most likely track revisions to the drafts already implemented — DKIM2, JMAP push and the calendar drafts are all still moving — rather than adding another protocol surface. Expect continued JMAP conformance fixes until the test suite stops producing them.
