What is Proton Bridge?
Proton Bridge is in pure maintenance: security patches and RFC compliance fixes dominate 2026
Proton Bridge has shipped six releases since February, none of which introduce user-visible features. The work is security vulnerability patching (August 2026 CVEs), RFC3501 IMAP compliance fixes, Go toolchain upgrades, and bug fixes in the Gluon IMAP server component. The v3.24.0 cycle added IMAP connection limiting and buffer pooling for message decryption — the most substantive user-affecting work in the reviewed period.
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.
Proton Bridge vs Chatwoot: editorial side-by-side
Proton Bridge
5.0COMMS
Proton Bridge is in pure maintenance: security patches and RFC compliance fixes dominate 2026
◆ Current state
Proton Bridge has shipped six releases since February, none of which introduce user-visible features. The work is security vulnerability patching (August 2026 CVEs), RFC3501 IMAP compliance fixes, Go toolchain upgrades, and bug fixes in the Gluon IMAP server component. The v3.24.0 cycle added IMAP connection limiting and buffer pooling for message decryption — the most substantive user-affecting work in the reviewed period.
◆ Where it's heading
Proton Bridge is in a sustain phase. The Gluon subsystem is getting more robust error reporting, CPU/memory bounds on the RFCP parser, and feature flags for controlled rollouts — signals of hardening a component that has historically caused reliability issues. No new end-user capabilities are visible in the roadmap from the changelog alone.
◆ Prediction
The next release will likely be another security or compatibility patch. Meaningful feature expansion would require Proton to signal a direction change for Bridge publicly, and nothing in this changelog points toward one.
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.
