Engineered For Autonomy

Autonomous capabilities that run on your machine

Everything runs as native child processes on your workstation with zero telemetry and full sandboxing.

01 / AUTONOMOUS WORKERS

Subagent tree orchestration for parallel missions

When tackling complex refactors or multi-file features, HermOS decomposes the problem and forks background subagents. One agent investigates schemas while another writes unit tests and verifies fixes.

02 / LOCAL TELEMETRY

Real-time token analytics stored in local SQLite

Monitor token consumption, prompt cache hit ratios, and model execution latency without a single byte of telemetry leaving your computer. All charts are rendered from your embedded SQLite store.

Questions & Answers

Frequently Asked Questions

Everything you need to know about security, API keys, and local execution.

Is HermOS completely free and open source? +
Yes. HermOS is MIT licensed open source software. There are no subscriptions, paywalls, or gated "Pro" tiers. You can read, build, and modify the source code on GitHub.
Does HermOS send any telemetry or project code to a remote server? +
No. HermOS operates with zero telemetry and has no login servers. When you converse with an AI model, queries route directly from your workstation to the configured provider API using your encrypted API key.
Can I use HermOS with local models offline? +
Yes. HermOS connects seamlessly to local inference runtimes including Ollama, vLLM, and LM Studio. When paired with local models, HermOS functions 100% offline with zero internet connectivity.
How are API keys stored on my computer? +
API keys are encrypted with AES-256-GCM and stored locally on your machine — never sent to our servers (there are none). The encryption key is generated per install and never leaves your device.
Where can I get help or report a problem? +
HermOS is developed in the open on GitHub. Bug reports and feature requests go to GitHub Issues, and questions, ideas, or show-and-tell belong in GitHub Discussions.
