# Open GSD: AI-Powered Development Workflow Suite

> Open GSD helps you plan, implement, verify, and ship software with AI agents. Three tools cover the full dev lifecycle: GSD Core, GSD Pi, and GSD Browser.

Open GSD is a suite of AI-powered developer tools designed to make working with AI coding agents fast, structured, and reliable. Whether you're wiring an AI runtime into a spec-driven pipeline, running an autonomous local coding agent, or giving an AI agent a powerful browser to work with — Open GSD has a tool for it.

  <Card title="GSD Core" icon="layer-group" href="/core/introduction">
    Spec-driven workflow engine for any AI coding runtime. Runs Research → Plan → Execute → Verify → Ship with 65+ slash commands.
  </Card>

  <Card title="GSD Pi" icon="robot" href="/pi/introduction">
    Autonomous local coding agent with TUI, web UI, worktree-isolated Git, and multi-provider model routing.
  </Card>

  <Card title="GSD Browser" icon="browser" href="/browser/introduction">
    Native CDP browser automation with MCP server mode, versioned element refs, and a live human-in-the-loop viewer.

## Get Started

<Steps>
  <Step title="Choose your tool">
    **GSD Core** if you already have an AI coding runtime (Claude Code, Cursor, Gemini CLI, etc.) and want a structured workflow on top of it. **GSD Pi** if you want a full standalone coding agent you run from your terminal. **GSD Browser** if you need browser automation for AI agents or CI pipelines.
  </Step>

  <Step title="Install in seconds">
    All three tools install with a single command:

    <CodeGroup>
      ```bash GSD Core theme={null}
      npx @opengsd/gsd-core@latest
      ```

      ```bash GSD Pi theme={null}
      npx @opengsd/gsd-pi@latest
      ```

      ```bash GSD Browser theme={null}
      npm install -g @opengsd/gsd-browser
      ```
    </CodeGroup>
  </Step>

  <Step title="Start your first project">
    Run the project initializer for your chosen tool and follow the interactive prompts to set up your first project.
  </Step>
