Atrium Agent Client vs Hermex

Atrium is the iPhone and iPad companion to Atrium for Mac. Follow your Codex and Claude tasks, send prompts, and manage your development work while your Mac runs the agents. • Pair by scanning the QR code in Atrium for Mac or opening a shared pairing link. • Connect to your Mac from any network with end-to-end encryption. • Read live agent replies and send prompts with images or voice transcription. • Choose agent models and reasoning settings. • Browse projects, review Git changes and diffs, and run workspace commands. • Switch between paired Macs and receive task notifications. Atrium for Mac is required. Download the latest macOS release from the link on the pairing screen. Codex and Claude require their respective command-line tools and accounts on your Mac. Optional voice transcription uses your own OpenAI API key.

Hermex is a native iPhone and iPad client for your self-hosted Hermes agent. It connects directly to your Hermes host. Existing Hermes Web UI servers keep working as legacy. Open existing sessions, start conversations, and follow streamed responses, tools, and reasoning as they arrive. Queue, steer, or stop an active run. Review file edits as diffs, browse workspace files, send photos and files, and dictate messages. Switch between Bots and Sessions, manage Kanban boards and Cards, browse Tasks, Skills, Memory, and Usage, and choose models, Profiles, and reasoning settings. Move to Hermes brings a Web UI server’s chats, drafts, and notifications over to your Hermes host. Live Activities keep working runs visible on the Lock Screen and Dynamic Island. Optional notifications let you know when work finishes or needs your attention. The share extension stages content from other apps for you to review and send. Agent execution happens on your configured server, not on the iPhone. Your server owns your conversations, tools, and workspace. Recent sessions and messages may be cached locally for read-only offline viewing; clear that cache from Settings. There is no Hermex-hosted agent backend, tracking, or analytics service. Optional push notifications use an open-source, self-hostable relay. Message previews are encrypted on your Hermes host and decrypted on your iPhone; the relay handles device tokens, notification metadata, and ciphertext, never message text, server URLs, or Hermes server credentials. Push is off until enabled. Hermex has no in-app account creation or in-app purchases. You need your own reachable Hermes server. Not affiliated with Nous Research.
