Understanding iMessage Number Types

  • Open Source: Run Spectrum on your own Mac and it automatically uses your iCloud account as your agent's iMessage number. Perfect for exploring and building locally before going production.
  • Managed Shared: Photon maintains a large pool of numbers and assigns each of your users a fresh one they have never received a message from before. Everything is handled for you with no infrastructure to worry about.
  • Dedicated Number: Numbers allocated just for your project. All your users text the same number and get connected to your agent. Nothing is shared with other tenants, giving you full control over your messaging identity.

Open-Source First by Design

  • Spectrum is built on a foundation of open source. The core system is fully open-sourced - you can self-host using first-party and community platform adaptors, no Spectrum Cloud service required. Choose our hosted service and we handle the rest, from configuration to scaling, so you can focus on building.
