Stalwart vs Wire: at a glance
What is Stalwart?
Stalwart races to implement the newest email standards across its all-in-one server
Stalwart is an open-source, all-in-one mail and collaboration server (SMTP/IMAP/JMAP/CalDAV) shipping a fast 0.16.x point-release train. Recent releases are dominated by standards implementation and protocol-conformance work, layered over steady security hardening and a long tail of targeted bug fixes.
What is Wire?
Wire turns on call-audio processing and WebSocket recovery by default while extending Collabora editing.
Wire is a secure-messaging client that has spent 2026 investing in call reliability, accessibility, and in-app document collaboration through its Collabora integration. Its July 6 release enables enhanced call audio processing (automatic volume, echo cancellation, noise suppression) and WebSocket recovery by default, and speeds up in-conversation and people search. Between substantive releases it ships unlabeled production rollups with no public notes.
Stalwart vs Wire: editorial side-by-side
Stalwart
5.0COMMS
Stalwart races to implement the newest email standards across its all-in-one server
◆ Current state
Stalwart is an open-source, all-in-one mail and collaboration server (SMTP/IMAP/JMAP/CalDAV) shipping a fast 0.16.x point-release train. Recent releases are dominated by standards implementation and protocol-conformance work, layered over steady security hardening and a long tail of targeted bug fixes.
◆ Where it's heading
The product is doubling down on being the most standards-complete self-hosted mail server: early DKIM2 and DMARCbis authentication, IDN support, encryption-at-rest for S/MIME, and a sustained push to pass the JMAP test suite. Security hardening runs alongside — DANE downgrade-attack defenses, auto-ban fixes, binary attestation on every build.
◆ Prediction
Expect continued rapid 0.16.x releases advancing draft email-authentication standards and JMAP conformance; a larger 0.17 or 1.0 milestone becomes likely once the JMAP suite fully passes and the DKIM2/DMARCbis drafts stabilize.
Wire
5.0COMMS
Wire turns on call-audio processing and WebSocket recovery by default while extending Collabora editing.
◆ Current state
Wire is a secure-messaging client that has spent 2026 investing in call reliability, accessibility, and in-app document collaboration through its Collabora integration. Its July 6 release enables enhanced call audio processing (automatic volume, echo cancellation, noise suppression) and WebSocket recovery by default, and speeds up in-conversation and people search. Between substantive releases it ships unlabeled production rollups with no public notes.
◆ Where it's heading
The arc runs from Collabora editor integration earlier this year toward reliability-by-default: audio processing, WebSocket message recovery, and MLS call-join fixes are now defaults rather than opt-ins. Accessibility (screen-reader support for entropy entry, self-deleting messages) is a recurring thread. E2EI certificate management continues to surface in the devices and update flows.
◆ Prediction
Expect continued reliability hardening and deeper Collabora document workflows; the next notable release likely extends default-on call quality or E2EI certificate handling. The frequent no-notes production rollups make a specific feature prediction unreliable.
