Self-hosted AI agent with persistent memory, a built-in learning loop, and 20+ messaging platform integrations.
Hermes Agent is an open-source, self-improving AI agent from Nous Research. It runs on your own server 24/7, remembers what it learns across sessions, and gets more capable the longer you use it. It turns successful workflows into reusable skills, connects to 15+ messaging platforms (Slack, Discord, Telegram, and more), and works with any LLM provider. All data stays local in a SQLite database. MIT-licensed and free, with costs limited to optional VPS hosting and LLM API calls.
Hermes Agent is an open-source autonomous AI agent by Nous Research. Unlike coding copilots or chatbot wrappers, Hermes has a built-in learning loop: it creates skills from experience, improves them during use, and builds a deepening model of who you are.
Hermes Agent itself is completely free and open source under the MIT license. There are no subscription fees or usage limits. Users only pay for optional infrastructure costs such as VPS hosting and the LLM APIs they choose to connect. Costs vary depending on the selected model and usage volume.
You can use virtually any LLM. Supported providers include Nous Portal, OpenRouter (200+ models), OpenAI, NVIDIA NIM, Hugging Face, Xiaomi MiMo, Kimi/Moonshot, MiniMax, and any OpenAI-compatible endpoint. Switch between models with a single command.
Yes — Hermes runs on a $5 VPS, on your laptop, or on serverless infra like Modal and Daytona that costs near zero when idle.
Hermes Agent focuses on long-running workflows, persistent memory, messaging platforms, and autonomous task execution. Tools like Claude Code and Cursor focus more heavily on software development workflows inside an IDE or terminal environment. Many users combine them for different tasks.Many developers use Hermes for automation and workflows alongside a dedicated coding tool.
The learning loop automatically creates reusable skill files from completed tasks. These skills can be loaded in future sessions and edited or removed by the user, helping Hermes improve efficiency on recurring workflows over time.
Hermes supports multi-user workflows and isolated environments via Docker and other backends. Team usage is possible, but users should configure permissions and security settings carefully depending on production needs.
