Every iMessage cross-platform hack so far had the same catch: you need a Mac running 24/7 as a relay server. BlueBubbles needs it. AirMessage needs it. Hermes Agent’s own previous iMessage support needed it.
Now it doesn’t.
What Happened
Ryan Zhu, the founder of Photon Spectrum, announced the Hermes Agent integration on X this morning. Hermes Agent can now send and receive iMessages through Photon’s managed cloud infrastructure. Works on Linux, Windows, any OS. No Mac required.
If you’ve been running Hermes Agent on a VPS and wished you could reach people on iMessage, this changes things.
What Photon Spectrum Actually Is
Photon Spectrum is an open-source TypeScript framework that connects AI agents to consumer messaging platforms. It’s MIT licensed, has 3.2k GitHub stars, and handles the messy Apple infrastructure on their end.
Photon manages Apple line allocation and abuse prevention on their infrastructure. You don’t have to touch any of it.
It supports iMessage, WhatsApp Business, Telegram, and Terminal today. Phone calls are coming soon.
How the Integration Works
Under the hood, Hermes runs a Node.js sidecar that holds a persistent gRPC stream to Photon’s edge network. Inbound messages flow from the gRPC stream through a loopback HTTP endpoint into Hermes’ Python adapter. Outbound replies go the reverse direction.
The sidecar handles automatic reconnection if the stream drops. SMS and RCS fallback kicks in automatically when iMessage isn’t available.
There’s one caveat: the SDK is TypeScript-only, so Python-based Hermes agents need that Node.js sidecar as a bridge. Extra runtime dependency, but it works.
Setup
Two commands. That’s it.
hermes photon setup --phone +155****4567
hermes gateway start --platform photonThe setup command triggers a device-code OAuth flow. You authenticate with your phone number, and you’re live.
Prerequisites: a Photon account, Node.js 18.17+, and a phone number. No public URL or tunnel needed. New to Hermes? My complete setup guide covers installation and configuration from scratch.
Pricing
Free tier: $0/month. Up to 10 users, unlimited daily messages, 5,000 messages per server per day, 50 new-conversation initiations per day.
Pro: $25/month. Up to 100 users.
Business: $250/line/month. Dedicated number, cold outreach (50/day), group API.
Enterprise: Custom. You own the numbers.
The free tier handles personal use and small bots. The catch: shared numbers mean different recipients might see different sender numbers, though each conversation stays consistent.
BlueBubbles vs. Photon Spectrum
BlueBubbles is the established option. Larger community, Flutter clients, battle-tested. But it requires a Mac running 24/7. If you don’t have Mac hardware, you’re out of luck.
AirMessage is simpler but also needs a Mac and is more Android-focused.
Photon Spectrum: no Mac required, managed infrastructure, free tier. The tradeoff is shared numbers on free versus owning your own Mac with BlueBubbles.
For Hermes Agent users specifically, Photon is the cleaner path. It’s a native integration, not a workaround.
The Real Significance
This is the first time iMessage access is genuinely cross-platform without hardware requirements. Every previous solution required a Mac somewhere in the chain.
Hermes Agent’s messaging gateway now covers 20+ platforms including iMessage. If you’re building automations or bots that need to reach people on iMessage, the barrier just dropped to zero cost and two commands.
You’re trusting Photon’s infrastructure instead of your own Mac. For most personal use cases, that’s an upgrade.
The Caveats
Shared numbers on the free tier could confuse recipients. If someone gets texts from different numbers in different conversations, that’s weird. It’s fine for bot-to-human messaging but not ideal for personal use where you want a consistent identity.
Photon is relatively new, launched around April 2026. Apple’s ToS on third-party iMessage access has historically been aggressive. BlueBubbles has survived so far, but Photon is bigger and newer. No enforcement yet, but it’s worth watching.
The gRPC stream approach is untested at scale compared to BlueBubbles’ direct Mac connection. No benchmarks exist yet.
Bottom Line
If you’re running Hermes Agent on a Linux VPS and want iMessage access, try the free tier. Two commands, zero cost, and you’ll have blue bubbles in minutes. The shared-number thing is a real limitation for personal identity, but for bot-to-human messaging or automations, nothing else comes close.
You’re early though. Photon is new, Apple hasn’t weighed in yet, and reliability at scale is unproven. But it’s free, so kick the tires.
