mautrix-gmessages

Overview

mautrix-gmessages is a Matrix puppeting bridge for Google Messages, written in Go and licensed under AGPL-3.0 (github.com/mautrix/gmessages). It pairs with the Google Messages app on a phone and turns its SMS, MMS and RCS chats into Matrix rooms, so Matrix clients and bots can read and reply. All messages pass through the phone, which has to stay online. Releases ship monthly; the latest is v26.10 (October 16, 2026).

Key features

• Text, photos, video, audio, voice messages and files up to 100 MB
• RCS replies, reactions, typing notifications and read receipts, including read receipts in groups
• Start chats with any phone number and create MMS or RCS group chats
• Rooms for recent chats, with optional history backfill
• Relay mode, double puppeting and optional end-to-bridge encryption
• HTTP provisioning API for logins and starting chats

Pricing

The software is free. You run it yourself next to a Matrix homeserver that supports application services (for example Synapse) and a PostgreSQL database, and you need a phone with Google Messages that stays connected. Login uses your Google account. The docs point to Beeper for fully managed instances.

How it compares to Linq

Linq sells a managed API with its own phone numbers, iMessage, RCS and SMS, signed webhooks and SDKs, with a free Hobby plan (20 contacts) and Pro from $260 a month. mautrix-gmessages has no iMessage, provides no numbers and has no messaging REST API or webhooks: your code talks to Matrix instead. It is free and self-hosted, while Linq is a fully managed service.

Best for

Teams that already run Matrix and want to read and send a phone's SMS and RCS conversations from Matrix clients or bots.
