Proton Bridge vs WATI
A side-by-side editorial comparison of Proton Bridge and WATI — release velocity, themes, recent moves, and the top alternatives to consider.
Proton Bridge vs WATI: at a glance
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 WATI?
WATI's feed is WhatsApp-commerce SEO content; its AI agent and MCP are referenced, not shipped here.
WATI's crawled feed is its marketing blog — WhatsApp-for-Shopify guides, seasonal message templates, competitive explainers (Meta Business Agent), and agent how-tos. Product capabilities surface only as topics: the Wati MCP server (build and audit agents from Claude), the "Astra" AI agent, and native WhatsApp voice calling. None are release notes.

Proton Bridge
2.5COMMS
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.
WATI
7.5COMMS
WATI's feed is WhatsApp-commerce SEO content; its AI agent and MCP are referenced, not shipped here.
◆ Current state
WATI's crawled feed is its marketing blog — WhatsApp-for-Shopify guides, seasonal message templates, competitive explainers (Meta Business Agent), and agent how-tos. Product capabilities surface only as topics: the Wati MCP server (build and audit agents from Claude), the "Astra" AI agent, and native WhatsApp voice calling. None are release notes.
◆ Where it's heading
The content bet is squarely on AI agents over WhatsApp — building and auditing agents from Claude via MCP, CRM-connected agent pipelines, and native voice. WATI is marketing itself as the WhatsApp-API layer beneath AI assistants, but because this feed is SEO, it tracks content cadence rather than shipped features.
◆ Prediction
Expect more agent- and MCP-centric content; confirming actual Astra, MCP, or voice releases will need WATI's product changelog instead of this blog.
