Spectrum

Bring agents to all the interfaces people already use

Website photon.codes
Overview

What it is

Nobody is going to download an app or visit a website to use your agent. Spectrum is an open-source framework that connects your agents to iMessage, Telegram, WhatsApp, and other interfaces people use every day, using one unified API. Your agent sends one message, Spectrum handles the formatting, delivery, and platform-specific logic natively, in under 1 second. Spectrum is free to start. Scale to Pro or Enterprise when you're ready.

Intent

I need it when

Reduce latency and improve reliability for real-time agent interactions

Spectrum delivers end-to-end latency under 1 second on Photon's edge-first infrastructure, compared to 500ms–2500ms on traditional CPaaS providers. This low-latency, high-reliability foundation is built specifically for agent-driven conversations at scale.

Build once and deploy agents across multiple messaging platforms with consistent behavior

Spectrum's unified API abstracts platform differences. Developers write one agent server and add providers for each interface (iMessage, WhatsApp, Telegram, Discord, Slack). Spectrum adapts message structure, formatting, and interaction patterns to match each platform's native constraints, ensuring conversations feel natural everywhere.

Scale agent messaging from early experimentation to millions of users without architectural changes

Spectrum handles transparent scaling from first user to production volume. The Business tier offers dedicated iMessage lines with unlimited daily messages and auto-scale capability. Built-in observability, audit logs, and message histories enable teams to monitor behavior and operate at scale with 99.9% uptime on Photon's edge network.

Deploy an AI agent to iMessage without requiring users to download a new app

Spectrum connects agents directly to iMessage, WhatsApp, Telegram, Discord, and Slack—platforms users already use daily. Agents run once on a unified server while Spectrum handles platform-specific formatting, native features (polls, reactions, threaded replies), and message delivery, eliminating the need for users to adopt new software.

Operate agents with security, compliance, and human oversight in production

Spectrum provides SOC 2-ready infrastructure with dedicated, isolated environments, restricted access by default, and secure traffic routing. Built-in human-in-the-loop controls, detailed audit logs, and message histories enable teams to flag conversations for review, monitor agent behavior, and maintain operational control.

Drop

Not a fit when

  • User needs multi-channel support beyond iMessage immediately—WhatsApp, SMS/RCS, Phone Call, and Telegram are listed as 'Coming Soon' and not yet available
  • User requires self-hosted infrastructure without any cloud dependency—Spectrum Cloud service is required for managed iMessage lines; self-hosting is possible but limited to open-source core
  • User needs unlimited group messaging on Free tier—Free plan supports only direct messaging; group messaging API is limited
  • User operates with very high cold outreach volume—Business and Enterprise tiers cap cold outreach at 50 new contacts per day per line
  • User requires sub-second latency with non-Photon infrastructure—Spectrum's <1s latency advantage is specific to Photon's edge network; other providers average 500ms–2500ms
