hermes-webui

Hermes WebUI is a browser frontend for Hermes Agent, a self-hosted autonomous AI agent that holds memory across sessions, runs scheduled jobs, and integrates with messaging platforms. Free and MIT-licensed.

Setup is moderate. You bring your own LLM API key (OpenAI, Anthropic, Google, DeepSeek, OpenRouter, others) and run the agent plus WebUI on your own hardware or VPS. Once running, the agent persists conversation context, learns from interactions, and can be triggered on a schedule. The web UI mirrors the CLI experience without locking you out when you close the terminal.

For solo developers and small teams who want an AI agent that isn't tied to ChatGPT or Claude.ai, this is a real option. Your conversations, your memory, your hardware. The cost is your LLM API bill, which can climb fast if the agent is making frequent calls. Solo: probably $10 to $50 per month in API spend depending on usage.

The catch is that "autonomous AI agent" is doing a lot of work in the description. These systems still hallucinate, still drift, still need supervision. Don't wire it into anything destructive without guardrails.
