Validate the app idea before you spend weekends building it Startup Idea Validation Agent is a GitHub repo of AI-agent workflows for indie developers, solo founders, and side-project builders testing B2C startup ideas before they build. It helps you move from “should I build this?” to a structured verdict by routing your prompt through idea generation, validation, market research, or pivot workflows inside Claude Code, OpenAI Codex CLI, or Cursor. Key features: • Tool-ready workflows – quickstart paths are documented for Claude Code, OpenAI Codex CLI, and Cursor • Four use modes – idea generation, idea validation, market deep dive, and pivot optimization • Scored validation memo – checks trend, competitors, desire, pricing, distribution, retention, CAC, and final score • Market signal research – README references TikTok Creative Center, Reddit, X/Twitter, App Store, and Google Trends • Persistent outputs – saves profiles, market insights, ideas, scores, competitors, pricing, and decision memos under memory/ It’s open-source (MIT license).
