Photon
Photon provides an open-source framework called Spectrum that lets developers connect AI agents to consumer messaging platforms like iMessage, WhatsApp, Telegram, and Slack through a unified API. The platform handles platform-specific authentication, event streaming, and native features, with managed infrastructure delivering sub-second latency and 99.9% uptime. Photon offers tiered pricing from a free tier to enterprise plans with dedicated iMessage lines.

Problem
Developers building AI agents must integrate each messaging platform (iMessage, WhatsApp, Slack, Discord, etc.) separately, handling distinct authentication, event models, and message formats. This fragmented approach increases development time, maintenance overhead, and limits the ability to reach users on the channels they already use.
Solution
Spectrum, an open-source framework from Photon, provides a unified API that connects a single agent server to multiple consumer messaging interfaces. By abstracting each platform into a "provider," Spectrum handles authentication, event streaming, and native feature exposure, allowing the same agent logic to operate across iMessage, WhatsApp Business, Telegram, Slack, Discord, Instagram, and more. The framework runs on Photon's low-latency edge network, delivering messages in under one second with high reliability. Developers can route messages automatically or specify fallback channels, and they can send rich content such as styled text, images, files, and interactive components that adapt to each platform's constraints. Management options include a web dashboard, REST API, and CLI for configuration, deployment, and analytics.
Target Audience
Primary customers are developers and product teams building AI-driven conversational agents who need to reach users across multiple consumer messaging platforms without maintaining separate integrations.
