What is Relay Studio?

Relay Studio is an open-source desktop application that wraps AI coding agents (Claude Code, OpenAI Codex) into a structured, visual build workflow. It automates the full cycle: planning, task decomposition, code generation, and review in a Kanban-style interface.

How to use Relay Studio?

  1. 1Launch Relay Studio and choose your engine (Claude Code CLI, OpenAI Codex CLI, or Anthropic API key).
  2. 2Create or open a project folder.
  3. 3Click 'New Feature', describe the feature, use @ to reference files.
  4. 4Choose to generate a specification or brainstorm interactively.
  5. 5Review the spec and approve it to decompose into tasks.
  6. 6Select build mode (Pause for Review, Auto-Pilot, Continuous) and start the agent.
  7. 7Watch the agent build each task; review diffs and approve/reject.
  8. 8Run your project, run code review, and create a PR.
