Kyllene

Kyllene is a free, open-source Android app (8.0+) that connects directly to a Hermes Agent dashboard running on your own server, homelab, VPS, or Tailnet. It lets you chat with your agent, approve commands before execution, and monitor work in progress—all from your phone with no Kyllene account or cloud service required.

Features include streaming replies with markdown and code syntax highlighting, voice and file support, command approval via notification, offline access to recent chats, and optional encrypted push notifications. Built with Kotlin Multiplatform, it prioritizes privacy by keeping all communication between your phone and your gateway, with no analytics or tracking.
