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.

What is Chatwoot?

Chatwoot is building an AI-first support platform, with Captain gaining audience targeting and macro automation reaching the keyboard-native workflow.

Chatwoot has moved decisively beyond multi-channel inbox. Voice calling launched in June, followed by a dedicated calls dashboard in August. The Captain AI assistant now handles configurable audience segments and schedule windows, and generates FAQ suggestions from resolved conversations. The Help Center gained a proper editorial draft workflow. The pace of major feature additions — at least two sparks in six weeks — signals a product that is shipping aggressively toward a full customer support OS.

Stalwart vs Chatwoot: editorial side-by-side

S6.3

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.

C7.5

Chatwoot is building an AI-first support platform, with Captain gaining audience targeting and macro automation reaching the keyboard-native workflow.

◆ Current state

Chatwoot has moved decisively beyond multi-channel inbox. Voice calling launched in June, followed by a dedicated calls dashboard in August. The Captain AI assistant now handles configurable audience segments and schedule windows, and generates FAQ suggestions from resolved conversations. The Help Center gained a proper editorial draft workflow. The pace of major feature additions — at least two sparks in six weeks — signals a product that is shipping aggressively toward a full customer support OS.

◆ Where it's heading

The Captain AI thread is the most directionally significant. Audience targeting, scheduling, reasoning transparency, self-generated FAQs, and performance metrics together sketch a product vision where support teams supervise AI rather than do first-contact response. WhatsApp integration is being fortified in parallel — BSUID support, guided setup, centralized templates — suggesting that WhatsApp is the primary channel driver for Chatwoot's growth. Voice calling is being hardened one release cycle after launch.

◆ Prediction

Captain will get more sophisticated handoff logic and routing controls. WhatsApp integration will likely expand to Business Calling or catalog features as Meta expands access. Voice calling will get queue-based routing and richer SLA integration.
