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.

GSD Core

Spec-driven workflow engine for any AI coding runtime. Runs Research → Plan → Execute → Verify → Ship with 65+ slash commands.

GSD Pi

Autonomous local coding agent with TUI, web UI, worktree-isolated Git, and multi-provider model routing.

GSD Browser

Native CDP browser automation with MCP server mode, versioned element refs, and a live human-in-the-loop viewer.
