What is Proton Bridge?

Proton Bridge has re-accelerated, with a quality-and-security pass across error UX, FIDO2, and Go modernization.

After a long pause through mid-2025, Proton Bridge resumed steady releases in early 2026 and has now shipped four versions in five months (v3.22 through v3.25). The work is uniformly internal: friendlier error messages, a Go 1.26 toolchain bump, FIDO2 path fixes, IMAP robustness, certificate-chain validation tightening, and the March 2026 security-patch sweep. Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.

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).

Proton Bridge vs Chatwoot: editorial side-by-side

P2.5

Proton Bridge has re-accelerated, with a quality-and-security pass across error UX, FIDO2, and Go modernization.

◆ Current state

After a long pause through mid-2025, Proton Bridge resumed steady releases in early 2026 and has now shipped four versions in five months (v3.22 through v3.25). The work is uniformly internal: friendlier error messages, a Go 1.26 toolchain bump, FIDO2 path fixes, IMAP robustness, certificate-chain validation tightening, and the March 2026 security-patch sweep. Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.

◆ Where it's heading

The product is in active maintenance mode rather than feature expansion. Investment is going into making the local sync layer more robust — mailbox conflict resolution, IMAP IDLE kill switch, vault retries on Linux — and the auth surface harder, with FIDO2 polish and TLS pin scoping. The arc reads as catching up on technical debt and shoring up security posture after a quieter year, not reshaping the product.

◆ Prediction

Expect the v3.2x cadence to continue with similar bug-fix and security flavor: more Go toolchain work, incremental IMAP edge-case handling, and continued error-UX tightening. The release notes do not surface anything that would hint at a v4 reshape or a meaningful new capability in the near term.

C6.3

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.
