Ship complete software features autonomously while sleeping

Developers, product managers, and technical founders who want to accelerate feature development

8-12 hours (overnight)

What Success Looks Like

Wake up to fully implemented, tested, and committed feature ready for review with minimal bugs or edge cases

Steps to Execute

Write comprehensive PRD describing desired feature and user flows

Use AI agent to convert PRD into atomic user stories with acceptance criteria

Set up Ralph bash script with project configuration

Run Ralph script before sleep, letting it iterate through stories

Wake up to completed feature, test manually for edge cases

Fix any discovered bugs with AI assistance

Deploy feature to production

Checklist

PRD covers all user scenarios and edge cases

Each user story has clear, testable acceptance criteria

Stories are ordered by logical dependency

Ralph script configured with correct file paths

Git repository is clean before starting

Agents.md files exist in relevant directories

Browser testing integration configured if needed

Inputs Needed

Clear feature requirements and user flows
Existing codebase with proper structure
AI agent access (Claude Opus 4.5 recommended)
Ralph script and configuration files
Token budget (~$30 for typical feature)

Outputs

Fully implemented feature code
Git commits for each completed user story
Updated agents.md files with learnings
Progress log documenting implementation decisions
Updated PRD JSON with completion status

Example

“E-commerce founder wants product review system. Writes PRD covering review submission, display, moderation. Converts to 12 atomic stories covering database schema, API endpoints, UI components, validation rules. Runs Ralph at 10pm, wakes up at 6am to find complete review system ready for testing.”
