About harnessrouter

HarnessRouter Community Edition: the self-hosted, Apache-2.0 edition of the unified interface for agent harnesses. Run Codex, Claude Code, Hermes, PI, DSH, and more through one API, with sessions, streaming, files, cancellation, and failure handling. Implements the Unified Harness Protocol (UHP), an open standard. Your keys, your infrastructure.

harnessrouter is one of 118 projects listed under Models & Routing on DSHToolkit. Model providers, routers, API key managers and proxies. Point DSH at DeepSeek, Kimi, Qwen, or anything else.

Installation

git clone https://github.com/HarnessRouter/harnessrouter.git
cd harnessrouter
# follow the README for install steps

Most DeepSeek Harness plugins install as npm packages or DSH extensions. After installing, restart DSH so the plugin registers. If the project ships a desktop client or a plugin market, you can install it with one click instead.

Install and configure harnessrouter

git clone https://github.com/HarnessRouter/harnessrouter.git
cd harnessrouter
pip install -e .
# then point DeepSeek Harness at the local package per its README

Python projects here ship as importable packages, so an editable install keeps your checkout and the runtime in sync while you evaluate it.

Configuration

# dsh.config.py — typical registration shape
plugins = [
    # confirm the exact import path in the README before using this
    "harnessrouter",
]

Registration shapes vary between plugins. The snippet above shows the common case — " copy the exact name from the README rather than trusting this example verbatim.

Is it the right choice?

• Choose it if you want something established but not ubiquitous — 3,263 stars is enough for real usage, small enough that the maintainer still answers issues.
• Licensing is Apache-2.0, which is permissive enough to vendor into a commercial product without a legal review.
• Stack: written in Python. If your team does not work in that language, every fix becomes a research task.

Things that commonly go wrong

• Version drift. DSH is young and moves fast. A plugin that worked three months ago may target an API that has since changed. Check the last commit date before you plan around it.
• No sandbox guarantee. Plugins run with the runtime's permissions. Read the source of anything that touches your filesystem, shell or API keys before installing it.
• Single maintainer risk. Most projects here are one person's side work. That is fine for a utility, risky for infrastructure you depend on.
