OpenMessage

Provides a local inbox that consolidates Google Messages (SMS/RCS), WhatsApp, and Signal into one people-first workspace with one row per person and route tabs per thread, solving fragmented messaging across separate browser mirrors and desktop apps. It is for individual consumers who manage personal conversations across multiple platforms on macOS. It is positioned against cloud-bridged aggregators by keeping messages, contacts, and sessions on-device with no hosted relay, and differentiates as free and open source with a shared local runtime that exposes the same inbox to AI assistants via MCP.
