Developer Crazh Holmes built Passive-Gen, a CLI tool that creates reproducible passive income ideas without APIs or internet connectivity. The TypeScript-based tool targets platforms like Gumroad and Etsy with deterministic output.

Most existing idea generators rely on fragile third-party APIs, creating unpredictable results. Holmes wanted something offline, inspectable, and repeatable. Passive-Gen produces structured JSON and markdown outputs using seed-based generation for consistent results.

The tool appeals to indie hackers and prompt engineers who want to build on stable foundations. While it doesn't guarantee success, it provides a clean starting point for niche research and product ideation. Holmes plans to expand into niche analysis and scoring improvements.

Boring tools often outlast flashy alternatives.
