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 chasing mail RFCs and its own storage layer at the same time
Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.

Chatwoot
6.3COMMS
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.
Stalwart
5.0COMMS
Stalwart is chasing mail RFCs and its own storage layer at the same time
◆ Current state
Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.
◆ Where it's heading
Two threads run through every release. One is RFC coverage across IMAP, JMAP, CalDAV and WebDAV, implemented close to the specification including drafts. The other is a long tail of protocol-conformance fixes, many of them cases where JMAP and IMAP disagreed about the same state. The newest release adds a third: memory and scheduling limits, which is what a server codebase starts doing when deployments get large enough for defaults to hurt.
◆ Prediction
Expect continued RFC additions across the JMAP and IMAP surfaces, with more of the storage-tuning work that v0.16.18 started as RocksDB deployments scale.
