Buyer
Teams that want an autonomous coding agent with open models (OpenRouter / local) and no seat lock-in.
What you get
- Persistent REPL with
/model,/mode auto|plan|build, live OpenRouter catalog - Agent loop: read / write / bash / glob / grep / list_dir
- Permissions: plan = read-only; build = write + bash
- Hybrid routing: fast-open / strong-open / frontier-byok
- Three model paths: OpenRouter (all models), OpenHost (host your own), or local Ollama
- MIT licensed — no seat fee
Quality claim
We sell a strong runtime (tools, permissions, routing, recovery) with open models by default. We do not sell “Opus quality on any open-source model.”
OpenHost is a separate product for hosting models; Harnes is the agent that talks to OpenRouter, OpenHost, or local endpoints.
