Beeper

Beeper is a universal chat app that brings 12+ messaging networks — WhatsApp, Instagram, Telegram, Signal, Messenger, X, Google Messages, Google Chat, Google Voice, LinkedIn, Discord and Slack — into a single unified inbox across macOS, Windows, Linux, iOS and Android. Built on the Matrix protocol and owned by Automattic, Beeper connects to networks on-device for privacy. For developers Beeper ships the Beeper Desktop API: a local-first REST API and built-in Model Context Protocol (MCP) server that runs entirely on the user's machine, letting agents and apps search chats, read and send messages, react, manage reminders and control the app. Official SDKs are published for JavaScript, Python, Go and PHP, alongside bridges for self-hosting and Android intents/content-providers.

Beeper publishes 7 APIs on the APIs.io network, including Accounts API, App API, Chats API, and 4 more. Tagged areas include Company, Consumer, Messaging, Chat, and Communication.

The Beeper catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Beeper’s developer surface includes documentation, API reference, getting-started guide, authentication, changelog, engineering blog, support, and 22 more developer resources.
