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 train is mostly fixes; call performance and notification controls are the only visible changes.
Signal Desktop ships a beta every week or two, and most notes read 'small tweaks, bug fixes, and performance enhancements.' The user-facing changes in the last two months: granular notification settings (badge contents, muted-thread behavior, a reset button) in 8.27, and lower CPU use on video calls plus a Windows shortcut to camera permission settings in 8.30. The rest is zoom levels and labeling yourself as 'You' in group search.
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
5.0COMMS
Signal Desktop's beta train is mostly fixes; call performance and notification controls are the only visible changes.
◆ Current state
Signal Desktop ships a beta every week or two, and most notes read 'small tweaks, bug fixes, and performance enhancements.' The user-facing changes in the last two months: granular notification settings (badge contents, muted-thread behavior, a reset button) in 8.27, and lower CPU use on video calls plus a Windows shortcut to camera permission settings in 8.30. The rest is zoom levels and labeling yourself as 'You' in group search.
◆ Where it's heading
The work clusters around everyday desktop friction: notifications, calls, appearance. Nothing in these entries touches the messaging model or adds a new capability. The 8.30 fixes show calling getting attention, a thread to watch.
◆ Prediction
Expect more call-quality and settings refinements across the next betas. These entries give no sign of a larger feature release.
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.
