Signal Desktop vs Stalwart
A side-by-side editorial comparison of Signal Desktop and Stalwart — release velocity, themes, recent moves, and the top alternatives to consider.
Signal Desktop vs Stalwart: at a glance
What is Signal Desktop?
Signal Desktop's beta returns to fix-only notes a week after its unread-filter release.
Signal Desktop ships a beta roughly weekly, and most builds since September have carried only generic fix notes. v8.32.0-beta.1 was the exception, extending the unread filter into folders and search and making uploads sturdier on poor connections; v8.33.0-beta.1 goes back to boilerplate. The previous visible gain was lighter CPU use in video calls on October 1.
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.
Signal Desktop vs Stalwart: editorial side-by-side
Signal Desktop
5.0COMMS
Signal Desktop's beta returns to fix-only notes a week after its unread-filter release.
◆ Current state
Signal Desktop ships a beta roughly weekly, and most builds since September have carried only generic fix notes. v8.32.0-beta.1 was the exception, extending the unread filter into folders and search and making uploads sturdier on poor connections; v8.33.0-beta.1 goes back to boilerplate. The previous visible gain was lighter CPU use in video calls on October 1.
◆ Where it's heading
After a summer of group-admin features, polls and member search, the desktop app is in a stabilization phase focused on calls, notifications and inbox triage. Visible changes arrive every two or three betas, in small increments rather than a headline release.
◆ Prediction
Expect more fix-only betas with an occasional inbox-organization or reliability tweak; the entries do not show a larger feature in progress.
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.
