Hermes WebUI: Phone-First Frontend for a Self-Hosted Agent

Hermes WebUI trending today on GitHub: 11.1K stars, +984 in a single day. It's the official web and phone frontend for Hermes Agent, the autonomous self-hosted agent that's been quietly growing on the Anthropic-adjacent stack. Three-panel browser layout: sessions on the left, chat in the middle, workspace files on the right. Voice input via Web Speech API, WebAuthn passkeys, optional password auth, persistent memory across sessions.

The product hook is mobile parity. Most agent CLIs assume you're at a desk with tmux open. Hermes WebUI gives you near-CLI feature parity from a phone. You can talk to your self-hosted agent, watch a long-running scheduled cron job complete while you're offline, browse the workspace, switch profiles. Built with Python backend and vanilla JS (no build step), drops on top of an existing Hermes install.

This category is filling out fast. Most chat-style frontends assume an assistant. Hermes is an autonomous agent that runs cron jobs and owns a workspace, and the UI for that didn't really exist. Hermes WebUI staking that ground at +1K stars/day is a signal. The next year of agent UX is mobile + voice + persistent workspace, not 'better terminal UI'.

The self-hosted angle is the other interesting bit. Cloud agent products (Manus, Devin, ChatGPT Agent) all bundle the agent with the runtime. Hermes' design assumes you bring your own infra and keys, which keeps the UI thin and lets the same WebUI front any LLM. For privacy-sensitive deployments and for hobbyists running their own stack, this is the right factoring.
