FAQ
What is a Ralph loop?
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 →
Why use Ralpher instead of Claude Code directly?
Claude Code is powerful, but running Ralph loops manually has friction:
Claude Code alone:
- • Terminal-based, no visual progress
- • Context lost if session crashes
- • Manual bash loop setup
- • One project at a time
- • You babysit the process
With Ralpher:
- • Visual board with story progress
- • Crash recovery, picks up where it left off
- • One-click loop execution
- • Manage multiple projects from dock
- • Walk away, come back to commits
Is Ralpher free?
Ralpher is free to download and use. You'll need a Claude Code subscription or API access to run the actual AI coding.
Is my code private?
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.
What platforms are supported?
Currently macOS only. Windows and Linux support coming soon.
