Bring your agents to the interfaces millions already use

About Spectrum

Spectrum is an open-source framework that connects your agents to iMessage, Telegram, WhatsApp, X, Discord, Instagram, and other interfaces people use every day. It serves developers and product teams who want to reach customers on the channels their users already use, enabling agents to live where conversations happen.

Key Features

To understand how Spectrum fits into workflows, consider its core capabilities for cross-channel agent integration and management:

Cross-Channel Connectors

Connect your agents to iMessage, WhatsApp, Telegram, X, Discord, Instagram, and other interfaces people actually use.

Channel Scoping

Narrow a generic space to channel-specific capabilities, with event handlers like onMessage and onLocationUpdate.

Real-time Event Hooks

Subscribe to live updates such as messages and location sharing to react in real time.

Developer-friendly API

Use a concise, modular syntax (Spectrum(providers, config)) to compose agents and attach handlers, with open-source tooling and examples.
