What is Chatwoot?

Chatwoot is turning its June voice launch into a channel a team can actually run.

Voice, introduced in June, now has a dedicated Calls area with filtering by inbox and assignee, per-call status and recordings playable in place, instead of calls buried inside conversation threads. Captain, the AI agent, mines already-resolved conversations for suggested FAQs and refreshes its own documents. Reporting charts became clickable, leading from a metric straight to the conversations that produced it.

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.

Chatwoot vs Stalwart: editorial side-by-side

C6.3

Chatwoot is turning its June voice launch into a channel a team can actually run.

◆ Current state

Voice, introduced in June, now has a dedicated Calls area with filtering by inbox and assignee, per-call status and recordings playable in place, instead of calls buried inside conversation threads. Captain, the AI agent, mines already-resolved conversations for suggested FAQs and refreshes its own documents. Reporting charts became clickable, leading from a metric straight to the conversations that produced it.

◆ Where it's heading

The pattern is consolidation rather than expansion. Each recent release takes something Chatwoot already shipped and adds the surface a daily operator needs: a home for calls, a payoff view for Captain, a path from a report number to the underlying threads. The AI work is aimed at reducing manual upkeep of the knowledge base rather than at answer quality.

◆ Prediction

Voice is the obvious place for the next round of automation parity with text, since this release gave it a dashboard but not workflow triggers or Captain participation.

S5.0

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.
