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.
What is Mailu?
Mailu ships one pinned release per issue, and most of them are Roundcube's.
The 2024.06 branch releases on demand: an issue or PR comes in, a pinned version goes out, and the changelog is one or two lines. Four of the six most recent releases are webmail-driven — three Roundcube bumps in this window alone, the latest to 1.6.18 clearing a TLS-configuration warning, an earlier one to 1.6.17 closing two CVEs. The remainder are Mailu's own code: an X-Forwarded-By header fix tied to a published advisory, sieve field escaping that repaired autoreplies and closed an injection path, and two admin-UI form flow corrections.
Chatwoot vs Mailu: editorial side-by-side
Chatwoot
7.5COMMS
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.
Mailu
5.0COMMS
Mailu ships one pinned release per issue, and most of them are Roundcube's.
◆ Current state
The 2024.06 branch releases on demand: an issue or PR comes in, a pinned version goes out, and the changelog is one or two lines. Four of the six most recent releases are webmail-driven — three Roundcube bumps in this window alone, the latest to 1.6.18 clearing a TLS-configuration warning, an earlier one to 1.6.17 closing two CVEs. The remainder are Mailu's own code: an X-Forwarded-By header fix tied to a published advisory, sieve field escaping that repaired autoreplies and closed an injection path, and two admin-UI form flow corrections.
◆ Where it's heading
This is a maintenance branch behaving exactly as a maintenance branch should, and the pinned-version model is the product: operators get upstream security work packaged and tagged without tracking Roundcube themselves. The security items divide cleanly — most arrive from bundled components, a minority from Mailu's own code, and the project patches both on the same cadence. Nothing in this window suggests new capability is being developed on this branch.
◆ Prediction
Expect the next release to follow the same trigger: a Roundcube advisory or a client compatibility report producing a single-line changelog and a new pinned tag. Any feature work would be happening on the main version, which this feed does not cover.
