What is Chatwoot?
Chatwoot adds voice to close the last channel gap in its omnichannel support suite
Chatwoot is an open-source omnichannel customer-support platform spanning live chat, email, WhatsApp, social channels, and a help center, with an AI agent called Captain. The headline recent move is voice: phone and WhatsApp calls now run in beta, closing the one major channel gap in an otherwise text-complete product. Around it, steady investment in Captain (auto-syncing knowledge base, Custom Tools to call external APIs, mobile AI Assist), help-center depth (a documentation layout, LLM-aware articles, bulk and translation tooling), and agent-workflow polish (assignment policies, a Participating view).
What is Stalwart?
Stalwart keeps hardening its mail server with standards conformance and at-rest encryption.
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.

Chatwoot adds voice to close the last channel gap in its omnichannel support suite
◆ Current state
Chatwoot is an open-source omnichannel customer-support platform spanning live chat, email, WhatsApp, social channels, and a help center, with an AI agent called Captain. The headline recent move is voice: phone and WhatsApp calls now run in beta, closing the one major channel gap in an otherwise text-complete product. Around it, steady investment in Captain (auto-syncing knowledge base, Custom Tools to call external APIs, mobile AI Assist), help-center depth (a documentation layout, LLM-aware articles, bulk and translation tooling), and agent-workflow polish (assignment policies, a Participating view).
◆ Where it's heading
Chatwoot is rounding out into a complete omnichannel support suite — adding voice to become genuinely all-channel while making Captain more capable and self-maintaining through fresh knowledge bases, external tool calls, and handoff tuning. The throughline is cutting manual upkeep and channel-switching for support teams, and pushing AI deeper into both answering and knowledge management.
◆ Prediction
Expect voice to mature out of beta with call routing and reporting (the team flagged these as next), and Captain to keep gaining agentic capability, given the voice-beta roadmap notes and the Custom Tools and auto-sync cadence.
Stalwart
5.0COMMS
Stalwart keeps hardening its mail server with standards conformance and at-rest encryption.
◆ Current state
Stalwart is an open-source all-in-one mail and collaboration server (JMAP, IMAP, SMTP). Recent releases focus on standards conformance and security hardening: passing the JMAP test suite, adding IMAP and OAuth protocol extensions, international domain names, and now encryption-at-rest for S/MIME. It is a steady point-release cadence aimed at correctness and interoperability.
◆ Where it's heading
The work points toward production maturity: closing JMAP spec gaps, adding high-availability primitives (Redis Sentinel coordination), and tightening TLS, DANE, and encryption. Stalwart is positioning itself as a standards-faithful, deployable alternative to legacy mail stacks rather than chasing new user-facing features.
◆ Prediction
Expect continued point releases that finish protocol conformance and expand operational features—high-availability backends, certificate handling, and encryption options—rather than a major feature pivot.
