Open-source agent you run on your own server, reachable on Telegram, WhatsApp, Signal and Slack
Hermes is an AI agent you reach on Telegram, WhatsApp, Slack and Discord. To start, self-host it. It reaches out on a schedule.
How Hermes works
Hermes runs on your own server, takes your messaging accounts, and becomes a persistent agent that learns your projects and reaches you on Telegram, WhatsApp, Slack or Discord. Its own line is that it is not a chatbot and not a copilot, and the distinction it draws is that it lives on your machine.
The model layer is entirely yours. It talks to OpenRouter for two hundred models, to any OpenAI-compatible endpoint, or to a local vLLM running on-premise, so the row for who provides the model has no single answer by design.
Two things are unusual. It writes its own skills: forty are built in and it adds more as it solves problems, and there are community hubs to browse and install from. And it is also an MLOps tool, a platform for generating tool-calling trajectories in parallel, running reinforcement learning experiments and exporting data for fine-tuning. Every other listing here is something you use. This is also something you harvest.
There is no privacy policy, and the site's position is that there is nothing to have one about: your data stays on your machine, no telemetry, no tracking, no cloud lock-in.
