개요

Ralph is an autonomous AI agent loop that runs AI coding tools (Amp or Claude Code) repeatedly until all PRD items are complete. Each iteration is a fresh instance with clean context. Memory persists via git history, progress.txt, and prd.json. Based on Geoffrey Huntley's Ralph pattern. The tool uses a workflow where you create a PRD, convert it to Ralph format, and then run Ralph to implement the stories. Ralph can be integrated with Amp or Claude Code, and the tool provides features such as automatic handoff and quality checks. To use Ralph, you need to install one of the AI coding tools (Amp or Claude Code) and a git repository for your project. You can set up Ralph by copying the files to your project, installing skills globally, or adding it as a Claude Code Marketplace. Key Files: ralph.sh: The bash loop that spawns fresh AI instances (supports --tool amp or --tool claude) prompt.md: Prompt template for Amp

사용 사례

Automated PRD Implementation

Feed a product requirements document to Ralph and let it iteratively run Amp or Claude Code until every item in the PRD is implemented.

Overnight Coding Runs

Kick off long-running autonomous coding sessions that loop without manual intervention, using git history to track progress and maintain context across iterations.

Backlog Burn-Down

Point Ralph at a list of outstanding tasks or features and let it grind through them sequentially, leveraging Claude Code or Amp to write and commit changes.

Solid for our team

We rolled this out across the team last quarter and it is genuinely easy to set up. The core workflow fits neatly into how we already work, and the onboarding removed a step we used to do by hand. A few rough edges remain, which is the main caveat, but it has held up under daily use.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the onboarding, and the value for money is strong caught me off guard. still, I'd recommend giving it a real trial.

Years in this space

I've evaluated a lot of these over the years. What stands out here is the onboarding — handled better than most — and it saves real time. The mobile experience lags is my one real gripe. Worth the time if this is your use case.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the dashboard, and the value for money is strong caught me off guard. still, I'd recommend giving it a real trial.

Compared a few options

Evaluated this against two competitors. Where it wins: the core workflow and it saves real time. On balance the feature set — especially the onboarding — justifies the 5 stars for our use case.

Does the job

Pretty happy overall. The API just works and it saves real time. A few rough edges remain can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Q&A

What is Ralph and how does it work?

Ralph is an autonomous AI coding loop that repeatedly runs Amp or Claude Code until all items in a Product Requirements Document (PRD) are completed. It uses git history as its memory to track progress across iterations.

Which AI coding agents does Ralph integrate with?

Ralph is designed to work with Amp or Claude Code, running them in a loop to autonomously complete tasks defined in your PRD.

What is the main use case for Ralph?

Ralph is best suited for developers who want to automate completion of a full PRD by letting an AI coding agent iterate continuously, using git commits as persistent memory between runs.
