Installation

Install the Core Package

npm install @openharness/core

pnpm add @openharness/core

yarn add @openharness/core

If you’re building a chat UI, install the framework-specific package:

npm install @openharness/react

npm install @openharness/vue

OpenHarness uses Vercel’s AI SDK for model access. Install the provider for your preferred model:

npm install @ai-sdk/openai

npm install @ai-sdk/anthropic

npm install @ai-sdk/google

Any AI SDK-compatible provider works with OpenHarness.

Set the API key for your model provider:

# OpenAI
export OPENAI_API_KEY=sk-...

# Anthropic
export ANTHROPIC_API_KEY=sk-ant-...

# Google
export GOOGLE_GENERATIVE_AI_API_KEY=...
