A Ralph loop is a technique created by Geoffrey Huntley that solves context rot in AI coding. Instead of one long session where the AI gets confused, each iteration starts with fresh context. The agent works through a structured PRD, logs progress to files, and picks up where it left off. This approach aligns with Anthropic's research on long-running agents using progress files to maintain state across sessions. Learn more →

With Ralpher:
Ralpher is free to download and use. You'll need a Claude Code subscription or API access to run the actual AI coding.
Yes. Ralpher is local-first. All your data stays in your repo under .ralph/. We don't have servers, don't collect telemetry, and never see your code. Your conversations go directly to Claude through your own API access.
Currently macOS only. Windows and Linux support coming soon.
Download Ralpher and let it do the heavy lifting.
