What is Ralph Wiggum?

Ralph Wiggum is a simple way to make AI coding tools keep working on a task until it’s actually done, instead of stopping after one try.

It was created by Geoffrey Huntley in May 2025 as a simple 5-line Bash script and blew up in January 2026. The name comes from Ralph Wiggum, the relentlessly persistent character from The Simpsons who never gives up.

Here’s how it works:

• You give an AI coding tool a task
• It works on it
• When it tries to stop, it gets fed the same prompt again
• The files it just changed are still there, so each iteration builds on the last one

Ralph Wiggum changes how you use AI from “chatting” with AI to managing autonomous “night shifts.” You can define a task before bed and wake up to find it completed (or that’s at least the marketing pitch).

It blew up online in late 2025 when developers started reporting impressive results. One developer reported completing a $50k contract for $297 in API costs 🤯

Ralph Wiggum works with various AI coding tools like Codex. There’s also an official Claude Code plugin for Ralph Wiggum, which helped popularize it.
